1. Introduction

Gartner Lee Limited is pleased to submit our draft Users’ Guide to the Surface Water Inventory of the Whitehorse Valley, prepared for the City of Whitehorse, Engineering Services in accordance with our letter proposal of February 2000. This Surface Water Inventory consists of updated waterbody mapping and accompanying geographic information system (GIS) data.

1.1 Background

In the winter of 1999/2000, the Department of Indian Affairs & Northern Development’s (DIAND) Water Resource Division initiated a Water Resource Inventory project for the Upper Yukon River. This initiative was started with a number of small projects in partnership with the Government of Yukon and the City of Whitehorse. This report and accompanying maps and digital mapping data on CD-ROM is a surface water features inventory at 1:20,000 scale and represents the City of Whitehorse’s contribution of the Water Resources Inventory initiative.

The City of Whitehorse is the largest population centre in the Yukon. As the City grows, and in an increasingly semi-rural fashion, there are increasing demands for and stresses on surface water resources in the region. The Yukon River is also the source of the City of Whitehorse’s urban water supply. In order to plan for and protect these urban and rural water supplies, environmental and fishery resources, an inventory and understanding of the surface water features is required.

This project provides a detailed surface water drainage network (streams, lakes and wetlands) with appropriate watershed identification. Existing 1:50,000 mapping is too coarse for City scale planning and often has an incomplete or incorrect hydrology network. Furthermore, the 1:20,000 scale mapping which already exists within the City boundaries suffers from lack of field verification. This project addresses these issues at a 1:20,000 scale.

The study area encompassed in this project is the four 1:20,000 orthophoto map sheets created by Triathlon Mapping Corp. for YTG in 1996 using aerial photography from 1994. This study area covers the Yukon River Valley from the Lewes River Bridge to Lake Laberge (Figure 1).

1.2 Objectives/Purpose

The propose of the Whitehorse Valley Surface Water Inventory project are as follows:

1. To identify watersheds of the City of Whitehorse and surrounding area. 2. To develop a more reliable stream network for the City of Whitehorse and surrounding area. 3. To identify a consistent nomenclature (toponomy) for streams and lakes in the Whitehorse area that are not identified in the Gazetteer of Canada Yukon Territory. 4. To provide data as a series of hardcopy maps (presented at 1:25,000 scale) depicting surface water features of the study area. 5. To provide surface water inventory data (watersheds, lakes, streams, wetlands and bibliography) in a digital format suitable for usage in a variety of mapping and geographic information systems (GIS). 6. To identify potential upstream impacts, or stressors, on the quality of the City of Whitehorse’s surface water supply.

1.5 Physiography

The following brief discussion of the study area physiography is modified from the Soil, Terrain and Wetland Survey of the City of Whitehorse (Mougeot GeoAnalysis and Agriculture and Agri-Food Canada 1997).

The Yukon River is the major drainage system which drains the study area. Tributaries of the Yukon River include Cowley Creek, Wolf Creek, McIntyre Creek and Croucher Creek as well as several unofficially named creeks and gullies that drain into the Yukon River. The larger lakes in the study area are well known to residents: Long Lake, Chadburn Lake, Schwatka Lake, Ear Lake and Cantlie Lake.

The Yukon Valley is a broad, terraced landscape. This area is composed of low relief glaciolacustrine, fluvial and aeolian material dissected by the Yukon River. Elevations of the valley floor ranges between 660m and 690 m above sea level.

The landforms of the Whitehorse area are attributable to the last ice age estimated to have existed between 35,000 and 10,000 years ago. The Whitehorse area has a complex sequence of glacial, glaciofluvial and glaciolacustrine deposits that are typical of deglaication in mountains terrain. These deglaciation features substantially affect and control surface water features observed in the study area today.

Gartner (20911-3ra0418.doc-05/01/01) 5 Lee Whitehorse Surface Water Inventory Users’ Guide

2. Watersheds (twhs_wsh)

Watersheds for the study area were identified for all major streams at 1:20,000 scale and are shown on Figure 2. Watersheds were delineated by selecting the mouth of a major stream and using the 1:20,000 topographic mapping to determine contributing area. Where watersheds extended outside the extent of the 1:20,000 scale mapping study area, 1:50,000 NTS topographic data was used to delineate that watershed. The watersheds are shown on Figure 2.

Some areas of Whitehorse do not have defined surface drainage, but rather consist of a series of closed depressions with no surface water outlets. These areas are primarily the hummocky kame and kettle topography of the Chadburn Lake and Long Lake areas. These areas of closed topography were delineated as discrete watersheds even though there is no regular surface drainage pattern.

Many of the watersheds in the Whitehorse valley are controlled by the presence of meltwater channels. There are relict stream valleys that were formed parallel to the main valley. In Whitehorse, the meltwater channels generally flow from south to north. These valleys are often incised into bedrock and oversized for the size of the stream they convey today. The present channels greatly influence the surface watershed, distorting them from traditional dendritic patterns. Furthermore, while surface water may be moving parallel with the valley wall contours, groundwater could potentially be moving perpendicular to the surface contours, and therefore, the surface watersheds identified as part of this inventory may not directly correspond to groundwater catchment areas and flow directions.

Deglaciation features such as kettle topography and meltwater channels significantly impact the surface water flow regimes and watersheds in the Whitehorse Valley. These surface features introduce a significant degree of complexity to the local hydrological regime. The complexity may result in surface watersheds which do no correspond to groundwater catchment areas. Therefore, when evaluating hydrologic conditions, both surface watersheds and groundwater flow systems should be considered together.

A more detailed discussion of Whitehorse’s physical geography and deglaciation features is presented in Mougeot GeoAnalysis and Agriculture and Agri-Food Canada’s excellent report entitled “Soil, Terrain and Wetland Survey of the City of Whitehorse”, prepared for the City of Whitehorse in 1997.

A summary of the watersheds is presented and discussed in section 2.2.

2.2 Discussion of Watersheds

The following sections provide a summary and discussion of the watersheds identified as part of this project. The watershed ID character is listed in brackets behind the watershed name.

2.2.1 Yukon River South (A)

Area: n/a This watershed represents the area of direct runoff to the Yukon River. For the purposes of this study, the Yukon River is divided into a north and south half, divided at Schwatka Lake and the City of Whitehorse’s water supply intake.

2.2.2 Cowley Creek (B)

Area: 21,270 ha The Cowley Creek watershed is a major drainage at the south end of the City of Whitehorse. The creek is controlled by a large meltwater channel or spillway created during deglaciation of the Carcross Valley. The upper half of the creek flows through a series of ponds created by melting permafrost (called themokarst) which have been modified by beaver dams. The upper most reach of Cowley Creek (upstream of Cowley Lakes) is called Dugdale Creek. This watershed also includes Kookatsoon Lake and the tributaries flowing from the northwest flank of Mt. Lorne. Tributaries in Mt. Lorne area are poorly understood and require further field assessment.

2.2.3 Cowley Lakes Subwatershed

Area: 4,020 ha This small subwatershed encompasses Cowley Lake, a large C shaped lake created by fluvial damming of the meltwater channel at this point. This lake is similar to Mary Lake in that there is no regular surface drainage from the lake to the nearby creek. Discharge from the lake is likely via the subsurface.

Figure 3. Cowley Lakes

2.2.4 Mirers Creek (C)

Area: 4,640 ha Mirers Creek joins the east side of the Yukon River just upstream from the Whitehorse City limits. This creek appears to be heavily controlled by meltwater channels. The mapping of this creek is very poor and require further field assessment. The name of the creek was found on an 1898 map of the Yukon produced by George M. Dawson.

2.2.5 Wolf Creek (D)

Area: 18,130 ha

Gartner (20911-3ra0418.doc-05/01/01) 9 Lee Whitehorse Surface Water Inventory Users’ Guide

Wolf Creek is the second major watershed at the south end of the City of Whitehorse. This stream comes from Coal Lake located west of the study area near Mount Granger. The upper reaches of the creek appear to be a large glacial spillway, where the mid-reaches of the creek cross-cut meltwater channels to join the Mary Lake meltwater channel.

This watershed forms the Wolf Creek Research Basin which is the focus of a long-term multidisciplinary research project that started in 1992. Originally, the Wolf Creek project concentrated on water research. Now research activities have expanded to include climate and climate change, vegetation, forestry, fisheries and wildlife. The lower reaches of Wolf Creek have also been the focus of salmon habitat enhancement activities by Fisheries and Oceans Canada

Mary Lake Subwatershed Area: 1,820 ha This small subwatershed of Wolf Creek represents the capture area of Mary Lake. Mary Lake’s origin is similar to Cowley Lakes in that it was formed by a shallow alluvial fan damming off a meltwater channel. In this case Wolf Creek has dammed the large Mary Lake meltwater channel (see Figure 4). There appears to be no regular surface drainage from the lake to Wolf Creek; discharge from the lake is interpreted to be via subsurface flow. Mary Lake has also been called Ruth Lake and Church Lake.

2.2.6 Cantlie Lake (E)

Area: 1,680 ha The Cantlie Lake watershed is a small closed watershed on the east side of Grey Mountain and has no surface outlet. The lake is stocked with Arctic Char by the Government of Yukon for sport fishery.

2.2.7 Sowdon Lakes (F)

Area 230 ha This watershed represents a small area of closed depressions (kettle topography) in the Wolf Creek subdivision area. There is no surface drainage for this area, and flow is interpreted to discharge via subsurface to a set of small springs to the east. These springs are located along the base of the terrace which forms the eastern edge of the Pineridge country residential subdivision. The lakes have been named after Wilf Sowdon, the first resident of the Wolf Creek area, prior to development of the subdivision. The kettles are formed by melting ice blocks that were deposited by the retreating glaciers. Outwash sand and gravel from the Mary Lake meltwater channel likely buried these blocks of ice in the Wolf Creek subdivision area.

Figure 4: Mary Lake

2.2.8 McRae Creeks (G)

Area: 6,110 ha The McRae Creeks area represents a series of small creeks, wetlands and beaver ponds that flow from Golden Horn and McIntyre Mountains eastward to the Yukon River. Sima Creek is located in the upper portions of this watershed and has been of interest lately for use as a water source for snow making at the Mt. Sima ski area. The watershed is interesting in that between the Copper Haul Road and the Alaska Highway, the creeks flow through a series of benches or terraces and wetlands. Recent beaver activity at the western (upstream) portion of the area has diverted the creek out of its original course (McRae Creek #2) to a more southerly course, forming McRae Creek #1. This diversion has dried up many of the wetlands and beaver ponds in this area. McRae Creeks #1 and #2 join at the Alaska Highway and flow through the Meadow Lakes Golf Course to the Yukon River.

Gartner (20911-3ra0418.doc-05/01/01) 11 Lee Whitehorse Surface Water Inventory Users’ Guide

Sowdon Creek Subwatershed Area: 1,780 ha Sowdon Creek is a subwatershed of McRae Creeks and represents an ephemeral (seasonal) stream that flows through the Wolf Creek country residential subdivision. The creek appears to flow only during spring freshet.

2.2.9 Basalt Creek (H)

Area: 850 ha Basalt Creek is a small stream which flows eastward across the Alaska Highway, north of the McRae industrial area. No historic name could be identified for this creak and so the proposed name is derived from the interesting columnar basalt cliffs that form the creek valley walls just west of the highway.

2.2.10 Chadburn Lake Complex (I)

Area: 4,070 ha This “watershed” represents an area of pitted outwash and kettle lakes (Figure 5) created by burial and subsequent melting of orphaned blocks of glacier ice during the last deglaciation. There is no developed surface drainage. This “watershed” represents the area contributing to the Selkirk Well Field. The Selkirk Well Field provides the City of Whitehorse’s winter groundwater supply. The lakes of this area are hydraulically connected to the Yukon River and Schwatka Lake. This is demonstrated by the water level rise observed in Hidden, Chadden and Chadburn Lakes after the completion of the Whitehorse Rapids Hydroelectric project and the creation of Schwatka Lake.

Figure 5: Pitted Outwash and Kettles of the Chadburn Lake “Watershed”

2.2.11 Copper Creek (J)

Area: 610 ha Copper Creek is a small closed watershed that flows from the former Whitehorse Copper Mine, through Crater Lake (just north of Mt. Sima Road) to Lower Crater Lake near the Alaska Highway. There is no outlet to Lower Crater Lake, which is a glacial kettle. Discharge is interpreted to flow subsurface through the outwash gravels and basalt bedrock to the Yukon River upstream of Miles Canyon. The name “Copper Creek” comes from operation and decommissioning plans of the Whitehorse Copper Mine. (Gadsby Consultants Ltd. 1991)

2.2.12 Canyon Creek (L)

Area: 560 ha Canyon Creek is another small watershed and flows just north of the Canyon Crescent subdivision. The creek originates from a set of wetlands just east of the ‘B’ valley tailings dam of Whitehorse Copper Mine and flows eastward toward the Yukon River. The creek discharges to a small pond with no outlet near the Miles Canyon Road. The pond is assumed to discharge via the subsurface to the Yukon River.

2.2.13 McLean Lake Creek (L)

Area: 2,110 ha McLean Lake Creek watershed is a very interesting watershed located on the western side of the Whitehorse valley. The upper reaches of the watershed are strongly controlled by meltwater channels that collect surface water from the eastern side of Mt. McIntyre. The creek originates from the McLean Lakes which are located near the mouth of several large meltwater channels.

An obscure diagram was located during the bibliographic research for this project that shows that a dam across the creek was located downstream of McLean Lake. This dam directed water into a ditch which conveyed the creek to Ice Lake which is located just north of the Lobird Trailer Park. This water was apparently used as coolant for airforce radar equipment installed at the location of the present day Lobird subdivision.

Today the creek flows to Hobo Lake which is a kettle lake located just west of Ear Lake. There is no outlet to Hobo Lake, and so flow from McLean Lake Creek likely infiltrate from Hobo Lake into the surrounding outwash gravels. There is no direct surface flow from McLean Lake Creek to Ear Lake.

2.2.14 Yukon River North (M)

Area: n/a This watershed represents the downstream or northern portion of the Yukon River watershed. The watershed represents areas of direct runoff to this portion of the Yukon River.

2.2.15 Hillcrest Meltwater Channel (N)

Area: 1,110 ha This watershed represents a large meltwater channel west of the Granger and Hillcrest subdivisions area. Waterbody features in the meltwater channel consist of a series of wetlands, but no continuous streams have been identified. Water from this watershed likely flows via subsurface to emerge as springs at the head of Baxter Street Gulch and Spook Creek. This area was investigated as a potential groundwater source for the City in a report prepared by Stanley Associates (1978).

2.2.16 Long Lake Complex (O)

Area: 1,930 ha The Long Lake Complex represents another area of pitted outwash and kettles similar to the Chadburn Lake Complex. This “watershed” area has no developed surface drainage and consists of a series of internally drained depressions and pothole lakes.

2.2.17 Croucher Creek (P)

Area: 11,200 ha The Croucher Creek watershed is a major stream on the eastern side of the Yukon River and drains an area east of Grey Mountain. The lower reaches of Croucher Creek have been investigated extensively by the Department of Fisheries and Oceans for salmon spawning and habitat. The mid to upper reaches of Croucher Creek branch and flow through a series of wetlands and beaver ponds. The exact location of the stream and its tributaries is poorly mapped and identified. Further field work is required to better understand the mid to upper portions of this watershed. Croucher Creek has historically been called Bell Creek.

2.2.18 McIntyre Creek (Q)

Area: 12,600 ha McIntryre Creek is the third major watershed on the west side of the Whitehorse valley. The headwaters of McIntyre Creek is Heather Lakes which are a picturesque set of lakes located along the Copper Haul Road near McLean Lake. The creek also receives discharge from Yukon Electrical Company’s micro- hydroelectric project that diverts flow from Fish Lake to McIntyre Creek via a pair of generating stations located along the Fish Lake Road. Much of the channel of McIntyre Creek is controlled by a set of large meltwater channels.

Reservoir Lake Subwatershed Area: 9,410 ha This subwatershed of McIntyre Creek represents the upstream area of the reservoir and intake for the lower half of the hydroelectric project. These watersheds do not include the Fish Lake watershed.

Upper Intake Subwatershed Area: 7,410 ha This area represents the portion of the watershed upstream of the upper intake of the McIntyre Creek Hydroelectric project.

2.2.19 Porter Creek (R)

Area: 940 ha The Porter Creek watershed represents a small perennial creek that flows from near McIntyre Creek to Hidden Lake in the Porter Creek subdivision. The upper portions of the creek are strongly controlled by meltwater channels. The creek flows parallel to the Alaska Highway, northward through Rabbit Foot Canyon. The creek discharges to Hidden Lake, which is another glacial kettle lake with no surface outlet. The 1:250,000 scale NTS mapping erroneously shows Porter Creek discharging to the Yukon River near the mouth of Macaulay Creek. A significant portion of flow into Porter Creek is controlled by discharge from Icy Water’s Fish Farm located on the Fish Lake Road. This flow is intern provided by a

Gartner (20911-3ra0418.doc-05/01/01) 15 Lee Whitehorse Surface Water Inventory Users’ Guide portion of the discharge from Yukon Electrical Company Ltd.’s upper stage of their micro-hydroelectric project. This discharge forms the headwaters of the creek.

2.2.20 Laberge Creek (S)

Area: n/a Laberge Creek is a large watershed that flows from the northeastern portion of the study area directly into Lake Laberge near the site of Upper Lebarge village. Swan Lake discharges to this creek. Much of this watershed lies outside of the study area.

2.2.21 Macaulay Creek (T)

Area: 1,660 ha Macaulay Creek is an interesting watershed formed by a series of small creeks flowing from behind the Kulan Industrial and Crestview Subdivisions. This creek’s interesting feature is that flow from a series of wetlands north of the Kulan Industrial Subdivision discharges in two different directions, depending on the season. The main creek flows northward around the Crestview residential subdivision. Seasonally, some flow discharges eastward, around the McKenzie RV Park. This secondary creek flows east across the Alaska Highway and into a closed depression behind MacDonald Road. From here, the water seeps into the ground and emerges as a series of springs to the east of a dividing ridge as shown on Figure 6.

The name Macaulay Creek was identified from a 1957 riverboat chart of the Yukon River. Macaulay Creek has been erroneously called Porter Creek and 9-Mile Creek in a variety of reports and water licences.

Yukon Spring bottled water operation draws their supply water from a well near the mouth of Macaulay Creek.

Figure 6. Macaulay and Tavern Creeks

Tavern Creek Subwatershed Area: 960 ha Tavern Creek is a subwatershed of Macaulay Creek. Tavern Creek flows from near the War Eagle Pit northward and across the Alaska Highway near Trail North truck stop. The creek flows into a closed depression between Centennial and Willow Roads. It is interpreted that the water seeps into the ground, flows under Macdonald Road Industrial Subdivision, to emerge as part of the Macaulay Creek springs to the north (see Figure 6). The name Tavern Creek was obtained from a 1982 Reid Crowther report of the War Eagle Landfill.

2.2.22 9-Mile Creek (U)

Area: 500 ha 9-Mile Creek is a small creek north of the Crestview Subdivision. It is not known if the creek flows perennially. The creek name was obtained from the 1957 riverboat chart and was likely named such due to its mouth being nine miles downstream from Whitehorse.

2.2.23 Little Takhini Creek (V)

Area: 2,575 ha Little Takhini Creek is the northern watershed in the City of Whitehorse before the Takhini River. The creek flows through the intersection of the Alaska and North Klondike Highways. In the past this creek has been erroneously referred to as Cousins Creek and 9-Mile Creek.

2.2.24 Takhini River (X)

Area: n/a The Takhini River is the largest major tributary of the Upper Yukon River. The Takhini flows from Kusawa Lake to the west to join the Yukon River at the north end of the City of Whitehorse. The river is interesting in that its morphology consists of a series of tortuous meanders as opposed to the Yukon River which is relatively straight.

2.2.25 Fish Lake (Z)

Area: 16,918 ha Fish Lake watershed is outside of the study area. Discharge from the lake is controlled by Yukon Electrical Company’s McIntrye Creek hydroelectric project. Originally, Fish Lake discharged to the Ibex River valley, but the hydroelectric project diverts flow to McIntyre Creek via a series of two penstocks and turbines.

3. Streams (twhs_str)

For the purposes of this study, a stream is defined as a reach or series of reaches of a watercourse having a continuous channel bed that is:

1. scoured by water flowing on a perennial basis, or 2. containing any mineral alluvium deposited by water that has flowed on a perennial or intermittent basis including a channel that may not be visible throughout its entire length due to overhanging or bridging vegetation or soil mats.

The primary feature for determining whether a watercourse is a stream under this project is the presence of a continuous channel bed. Water flow in the channel may be perennial, ephemeral (seasonal), or intermittent (spatially discontinuous).

The basic procedure for stream mapping in this project was the assessment and verification of watercourses portrayed on the 1996 1:20,000 scale mapping (Triathalon Mapping Corp.) of the Whitehorse area. Although this mapping is best regional mapping of the City and surrounding area, it is notoriously poor for its portrayal of streams which have not been field checked or verified. Therefore, this project focused on correcting these problems. Verification of stream locations was conducted by:

♦ limited field checking;

♦ local knowledge;

♦ review of larger scale mapping (ie. orienteering maps, etc.); and

♦ interviews with rural residents and trail users.

Based on this assessment stream locations were corrected and classified as follows:

1. definite (present and with interpreted perennial flow); 2. ephemeral (seasonal flow); 3. connectors (where the stream flows through a lake or wetland); 4. pipelines or penstocks; and 5. not present (deleted from mapping and database).

Streams that could not be verified or assessed as part of this project, usually due to remote locations, were placed in a separate data layer (twhs_sti). No reliance on the location or presence of the indefinite streams should be made until the indefinite stream has been verified in the field.

Gartner (20911-3ra0418.doc-05/01/01) 19 Lee Whitehorse Surface Water Inventory Users’ Guide

Following identification of stream, streams were divided into reaches. The following is the definition of a reach and is adapted from the Fish-stream Identification Guidebook, British Columbia Forest Practices Code (1998):

A reach means any water course that has a continuous channel bed that is at least 100 m in length, measured from the following locations to the next of any of the following locations:

1. Significant changes in stream channel form or confinement (and/or coupling), such as the change from a single channel to braided, multiple channels, or at the change from a wide floodplain to a confined canyon; 2. Significant changes in gradient; 3. Significant changes in streambed and bank materials, such as a change from erodible to non-erodible materials; and 4. Significant tributary confluences.

On the accompanying maps (Map 1 & 2) a reach break marks the boundary between adjoining reaches. Each reach on a stream is assigned a unique number in an upstream ascending order, the first being the reach closest to the mouth of the stream.

3.1 Data Description

Stream mapping data is contained in data files twhs_str and located in the \data directories on the CD- ROM. Stream lines contain the following attribute data:

Table 2. Stream Attribute Data Fields Stream Data Field Description StreamID This field is blank but should be used for the stream Watershed Code which is currently being developed by the Dept. of Fisheries and Oceans Type Type of stream, for example, definite, ephemeral, connector or pipeline.

Gartner (20911-3ra0418.doc-05/01/01) 20 Lee Whitehorse Surface Water Inventory Users’ Guide

Indefinite, or not-verified stream data, as portrayed on the 1996 1:20,000 scale mapping, is contained in the data files twhs_sti and located in the \data directories on the CD-ROM. Since these indefinite streams are not verified and should be used only for general presentation purposes, the line data contains no meaningful attribute data. The user is strongly cautioned when using this data layer since the data has not been vetted.

Data fields are described in more detail in the following sections. Much of the following material is adapted from the B.C. Resource Inventory Committee’s Reconnaissance (1:20 000) Fish and Fish Habitat Inventory: Standards and Procedures (1998).

Appendix B provides the stream attribute data in tabular format.

3.1.1 StreamID

This field is currently not used. The space should be used for a unique stream identifier code. Currently, Fisheries and Oceans (Yukon region) is developing a Watershed Code system. This watershed code system is based on the B.C. system of stream identification and will give every stream and waterbody a unique numeric identifier. Once DFO has completed the system, the waterbody codes should be incorporated into this database.

3.1.2 Type

Type is a one-letter code that describes the basic stream classification. Stream type codes are as follows:

Table 3. Stream Type Codes Type Code Description d Definite (perennial) stream e Ephemeral (seasonal) stream p Stream flows in pipeline (ie. hydroelectric penstocks) w Water link or connector – used to connect streams and build hydrology network when streams flow through lakes, wetlands or large rivers.

This field is useful for thematically mapping the streams layer in a geographic information system.

3.1.3 Reach Number

Reaches are segments of streams that show similar geomorphic characteristics, including discharge, channel pattern, channel confinement, gradient, and streambed and bank materials. Stream reaches were identified using the existing topographic mapping and limited airphoto interpretation.

Gartner (20911-3ra0418.doc-05/01/01) 21 Lee Whitehorse Surface Water Inventory Users’ Guide

A reach break marks the boundary between adjoining reaches. Each reach on a stream is assigned a unique number in an upstream-ascending order, the first being the reach closest to the mouth of the stream.

Like stream reaches, lakes and connected wetlands are numbered. For lakes and wetlands, each reach is assigned a unique number in a sequential, upstream-ascending order, consistent with the stream reach numbering system. Figure 7 illustrates reaches, reach breaks and related attribute data.

Figure 7. Watershed With Stream Reaches, Lakes, and Related Attribute Data.

3.1.4 Name

This field provides the name of the stream. Stream names were identified from the published names on NTS topographic maps. Many of the streams in the study area do not have a gazetted name, and therefore names were identified from historical documents or local reference. Appendix E provides a summary of stream and lakes names identified during this project and the source of that name.

Gartner (20911-3ra0418.doc-05/01/01) 22 Lee Whitehorse Surface Water Inventory Users’ Guide

3.1.5 Order

Order is a method used to describe the relative size and topology of a stream in a network. The determination of order should include all identified channels (including intermittent channels), as shown in Figure 8. Order provides a relative measure of stream size. For example, very small streams such as the headwaters of Macaulay Creek are first order streams, where the lower end of Wolf Creek is a 5th order stream. Figure 8. Comparison of stream magnitude and order (from R.I.C. 1998)

3.1.6 Elev_up

The field provides the upstream elevation (in meters above sea level) for the particular reach. Elevations were estimated from the 5 meter contour mapping.

3.1.7 Elev_dn

The field provides the downstream elevation (in meters above sea level) for the particular reach. Elevations were estimated from the 5 meter contour mapping.

3.1.8 Length

This field provides the horizontal length (e.g. not slope length) of the stream reach, measured in meters.

3.1.9 Gradient

Gradient is the slope (in percent) or rate of vertical drop per unit of land of the channel bed. Gradient is calculated using map-based measurements of upstream and downstream elevations of a reach, and reach length. Gradient is an important stream characteristic when looking at potential for fish and fish habitat.

3.1.10 Pattern

Pattern describes the path of the channel banks in relation to a straight line. Stream channel pattern is an important factor in determining channel stability. Pattern types were assessed using existing topographic mapping and airphoto interpretations. Pattern types are shown in Figure 9:

Figure 9. Stream channel patterns (from R.I.C. 1998)

3.1.11 Confinement

Confinement is a visual assessment of the degree to which the lateral movement of a river channel is limited by relic terraces or valley walls, as illustrated in Figure 10:

4. Lakes (twhs_lks)

A very general lake inventory was also completed as part of the Whitehorse Surface Water Inventory. Work consisted primarily of identifying attribute data for lakes as portrayed on the 1996 1:20,000 scale mapping (Triathalon Mapping Corp.). Basic attribute data was added to each lake, such as name (if known), area, elevation, genesis, etc. Each lake is assigned a Lake Group code which uniquely identifies the lake, lake cluster or interconnected lakes.

Under the Canadian system of wetland classification developed by the National Wetlands Working Group (1988), a small body of standing water with a depth less than 2 meters is a shallow open water wetland. A lake is an open waterbody with a depth greater than 2 m and with less than 25% of its surface area covered with wetland vegetation. By default, any open waterbody less than 2 m deep is a wetland. Due to the limited scope of this project, it was not possible to distinguish shallow, open wetlands from lakes using airphotos and existing information; therefore, further field work and studies should be conducted to distinguish the “lakes” identified as part of this project from shallow open water wetlands. Wetlands used in this project were from Mougeot GeoAnalysis and Agriculture and Agri-Food Canada (1997)—see section 5 of this report.

4.1 Data Description

The lake mapping database is contained in data files twhs_lks and located in the \data directories on the CD-ROM. In the digital mapping data, lake polygons contain the following attribute information:

Data fields are described in more detail in the following sections. Much of the following material is adapted from the B.C. Resource Inventory Committee’s Reconnaissance (1:20 000) Fish and Fish Habitat Inventory: Standards and Procedures (1998).

Appendix C provides the lake attribute data in tabular format.

4.1.1 LakeID

This field is currently not used. The space should be used for a unique waterbody identifier code currently being developed by the Yukon section of the Department of Fisheries and Oceans. This watershed code system is based on the B.C. system of waterbody identifying and will give every stream and waterbody a unique numeric identifier. Once DFO has completed the system, the waterbody codes should be incorporated into this database.

4.1.2 Name

This field provides the name of the lake. Lake names were identified from the published names on NTS topographic maps. Most of the lakes in the study area do not have a gazetted name, and therefore names were identified from historical documents or local reference. Appendix E provides a summary of stream and lakes names identified during this project and the source of that name.

4.1.3 Stream_Name

This field is used if a stream flows through the lake. The name and reach of that stream is identified in the stream_name and reach fields. This relationship is illustrated in Figure 7. These fields are left blank if the lake has no stream inlets or outlet.

4.1.4 Reach

This field is used if a stream flows through the lake. The name and reach of that stream is identified in the stream_name and reach fields. These fields is completed with “0” if the lake has no stream inlets or outlet.

4.1.5 Lake_Group

All lakes in the study area are assigned a two-letter lake group code. Lake Groups are clusters or series of interconnected lakes. Lakes, which are isolated because of barriers or do not have inlets or outlets, constitute one-member lake groups (Figure 11). Clusters of pothole lakes (ie. Hidden Lakes) are assigned one lake group code even though they are not interconnected by streams. All lakes within a group are designated as primary or secondary. The first letter in the two-letter lake code is the WatershedID of the watershed in which the lake lies. For example, Hidden Lake in the Porter Creek

Gartner (20911-3ra0418.doc-05/01/01) 27 Lee Whitehorse Surface Water Inventory Users’ Guide subdivision is lake group RB, and therefore located in the Porter Creek Watershed (R). and “B” is the unique letter code for the Hidden Lake group. An example of this grouping numbering system with respect to watersheds is illustrated in Figure 7. A list of watersheds and watershed IDs is presented in Section 2.2 and Appendix A of this report.

4.1.6 Lake_Class

All lakes within a group are designated as primary or secondary (P or S respectively). In general, primary lakes are: 1. Lakes that play a dominant role. These generally have the largest surface areas, and (or) are central in a cluster or chain of lakes. 2. Lakes that represent the physical characteristics of most of the lakes in the group. Only one lake in a group is designated as primary; all other lakes in the group are designated as secondary lakes. Figure 11 illustrates primary and secondary lakes and lake groups. Primary lakes are shaded in this illustration. Lake group A contains a cluster of seven lakes. Lake group B is an isolated lake. Lake group C represents a series of two lakes.

4.1.7 Genesis

This field provides an interpretation of the genesis, or formation of the lake. The lake genesis identified as part of this project are based on airphoto interpretation and local knowledge of geomorphological conditions only. No field work was conducted for identification of lake genesis, and therefore more detailed research may identify different lake formation mechanisms from that presented in this study. The mechanisms for lake genesis are adapted from Hutchinson’s Treatise on Limnology (1957). The user is referred to this publication for further information on lake genesis. Table 5 provides a summary of the lake genesis encountered in the study area and some basic summary information. A total of 428 “lakes” were identified in the study area Table 5.

Anthropogenic Lakes (AL) Lakes formed as a result of human action--specific actions not specified. For example, several lakes, including Swamp and Murray Lakes, were formed by building of the railway and damming of small streams. Sewage treatment lagoons are included in this category. Lakes formed in quarries and as water reservoirs are classified as AQ or RV lakes respectively.

Gartner (20911-3ra0418.doc-05/01/01) 29 Lee Whitehorse Surface Water Inventory Users’ Guide

Quarry Lakes (AQ) These are lakes formed when retired gravel pits or open pit mines fill with water and are large and deep enough to be called lakes. Examples include Keewenaw pit near Wolf Creek or War Eagle Pit.

Beaver Dam Lakes (BV) These are lakes formed as a result of beaver dams, (e.g. Marwell Ponds). Although often relatively small in size, beaver dam lakes are one of the most common type of lake in the Whitehorse valley, comprising almost 25% of the lakes in the study area.

Many beaver dam lakes may have another genesis, but when the lake appears to have been substantially altered by beaver activity, it has been classified as a beaver dam lake. For example, there are a series of ponds created by melting of permafrost along Cowley Creek (near Cowley Lakes). However, these ponds have been taken over and modified extensively by beavers and their dams. Many of the small ponds found in meltwater channels appear to have been created by beavers.

Dead Ice Complex Lakes (DC) These are lakes formed as a very large section of valley glacier melts. Dead ice complex lakes, often known as “pothole” lakes, are formed when outwash (gravels and sands) deposited around a large block of glacial ice forms a basin after the ice has melted. However, compared to kettle lakes, the kame terrace surrounding the dead ice complex lake may be of more variable height, and they may have eskers running across them and they always have multiple basins. Chadburn Lake, Long Lake and Hidden Lakes are dead ice complex lakes—see Figure 5. The largest lake within the City of Whitehorse of this type is Chadburn Lake.

Alluvial Fan Dam Lakes (FD) Alluvial fan dam lakes are formed when a stream deposits an alluvial fan across a valley, damming it to form a lake. Often a tributary creek will block a meltwater channel, forming a lake in the meltwater channel (see Figure 4). Large examples include Mary Lake and Cowley Lakes. Many of the small ponds found in the meltwater channels along Mount McIntyre are likely caused by small alluvial fan dams blocking the channel.

Glacial Kettle Lakes (GK) Glacial kettle lakes, often known as “pothole” lakes, are formed when outwash (gravels and sands) deposited around a large block of glacial ice forms a basin after the ice has melted. Though breakup of the ice-block could have resulted in the formation of more than one basin, the kame terrace is at the same general level around the lake. For example, Hidden Lake in Porter Creek, Pothole and Harmon Lakes near the Livingstone Trail Sewage Treatment facility are examples of kettle lakes. Glacial kettle lakes,

Gartner (20911-3ra0418.doc-05/01/01) 30 Lee Whitehorse Surface Water Inventory Users’ Guide along with dead ice complex lakes, are the most common lake type in the Whitehorse valley, together comprising 28% of the lakes in the study area.

Moraine Lakes (GM) These are lakes formed by unconsolidated, glacially derived materials such as esker and moraines that are deposited in a narrow point, in a valley or other depression and act as a dam. Many of the lakes in the Miners Range north of Takhini Hotsprings are likely of this type. Mud Lake just north of the study area, is a good example of a moraine dammed lakes. Also, some “ground moraine” lakes which are lakes filling basins created on the glacial till surface are included in this category. Examples of this include Paddy’s Pond and Ice Lake.

Glacial Scour Lakes (GS) These are lakes formed in basins scoured into rock. Glacial sours form the very large linear lakes of the Southern Yukon. These type of lakes form the largest lakes in the study area, including Lake Laberge and Cantlie Lake. Cantlie Lake is the largest lake in the study area at 215 hectares.

Landslide Lakes (LL) These are lakes formed by mass movement dams. It is interpreted that several small ponds in high elevation meltwater channels on the slopes of Mount McIntyre may have formed by this process. Potentially over steepend meltwater channel walls, or permafrost rich soils may have flowed into the channel, creating a dam and small lake. Only four such lakes were identified as part of this study, and further research could be conducted to confirm this interpretation.

Levee Lakes (LV) Levee lakes are formed when a levee deposit, along the banks of the main channel, traps water. This processes is interpreted to be responsible for the creation of Swan Lake. Furthermore, it is interpreted that the growth of the Yukon River delta into Lake Laberge may be creating levees that are annexing Shallow Bay from the rest of the lake.

Other Lakes (OT) This is a catchall category for anomalous lakes. These include Kookatsoon Lake which the author interprets to be a deflation lake (created by winds scouring a depression), and Crater Lake which may be formed as a plunge pool by meltwaters pouring off the Miles Canyon Basalt flows.

Oxbow Lakes ( OX) Oxbow lakes are formed when an avulsion cuts off a portion of the meandering channel between two bends. A good example is the oxbow lake on the north side of the Takhini River, approximately 5 kilometers upstream from the confluence with the Yukon River.

Gartner (20911-3ra0418.doc-05/01/01) 31 Lee Whitehorse Surface Water Inventory Users’ Guide

Reservoir Lakes (RV) These are lakes formed when areas are dammed, for example, for electric power or water supply for industry, agriculture, domestic use, or wildlife. Examples include Hotsprings Pond, Reservoir Lake and Icy Waters’ Pond.

Themokarst Lakes (TK) These are small ponds created by melting of permafrost rich soil, causing collapse and small ponds. Good examples of these are in the Cowley Creek valley near Cowley Lakes (see Figure 3). Many of these ponds have been utilized and modified by beavers.

5. Wetlands

Wetlands of the City of Whitehorse were mapped by C. Mougeot, S. Smith and C. Kennedy for the City of Whitehorse Planning Department in 1996. The results of this mapping are reported in Soil, Terrain and Wetland Survey of the City of Whitehorse (Mougeot GeoAnalysis and Agriculture and Agri-Food Canada 1997). The wetlands were digitized and attribute databases were built for the City by Gartner Lee Limited in 1997. This wetland mapping has been included in this data set for reference. For a more detailed discussion of wetlands in the Whitehorse area, the reader is referred the 1997 Mougeot GeoAnalysis report.

It is important to note that this 1996/97 wetland mapping does not encompass the entire study area, but only the southern three quarters of the City of Whitehorse. Areas not mapped within the City Limits include north from Cousins Airfield to the Takhini River and east of the Yukon River, north of Croucher Creek.

5.1 Data Description

The wetland mapping database is contained in data files twhs_wet and located in the \data directories on the CD-ROM. Wetland polygons contain the following attribute data:

Table 6. Wetland Attribute Data Fields Wetland Data Field Description WetlandID Unique wetland identifier number Class1 General type of wetland Form1 Define the morphological type, or form of the wetland Type1 The vegetation within the wetland Class2 If two wetland types exist within a polygon, this field may be used to describe it Form2 When a second wetland class is present, this field may be used to define its form Type2 When a second wetland class is present, this field may be used to define its vegetation Modifier This field contains additional modifying information about the wetland Air_Photo This field is used to indicate the air photo used to evaluate the wetland Site# This field is used by Agriculture Canada to indicate their site plot number

Complete descriptions of the attribute fields can be found in Digital Surficial Mapping of the City of Whitehorse Data Design Document (Gartner Lee Limited 1997).

Appendix D provides the lake attribute data in tabular format.

6. Spatial Bibliography

As part of the research conducted for this project, a surface water bibliography was created. This bibliography contains a listing of many of the surface water related studies, research, water licences, and water monitoring reports. The bibliography is not exhaustive, but does contain reference to records maintained by:

♦ DIAND Water Resources

♦ Environment Canada, Water Survey

♦ Department of Fisheries and Oceans

Where possible, these reports have been associated with a point location. This geographically related, or spatial bibliography is included in the GIS data set. The spatial bibliography database is contained in data files twhs_bib and located in the \data directories on the CD-ROM.

Appendix F provides the bibliography database in tabular format. Note that some of the reports listed in Appendix F may refer to several waterbodies, or may not be point specific, and therefore are not in the spatial (GIS) bibliography. These include reports such as those prepared as part of the Alaska Highway Gas Pipeline in the 1970s.

7. Data Structure and Formats

This section of the report provides a summary of the digital data provided in the accompanying CD- ROM. This disk presents the surface water inventory data sets in digital format for the Whitehorse area which was compiled as part of this project. The data includes new stream networks, lakes, wetlands and watersheds. Much of this data was previously available in digital format; but has been extensively elaborated on or field verified as part of this project. A subset of a public domain 1:20,000 topographic data provided by the City of Whitehorse and the Government of Yukon is included for georeference purposes.

All data is provided in the UTM, Zone 8 coordinate system (NAD 83) which is commonly used by the City of Whitehorse for accurately plotting data at the local scale. Data files are also presented in several different file formats to allow easy importing of data into commercial GIS software:

♦ MapInfo Tables (*.tab),

♦ ArcView® Shapefiles (*.shp),

♦ ARC/INFO® Interchange (*.e00), and

♦ CAD interchange (*.dxf))

This CD-ROM also includes ArcExplorer®, a geographic data explorer for Microsoft Windows, developed by Environmental Systems Research Institute, Inc (ESRI). The software can be freely distributed and used (subject to their licensing requirements). The ArcExplorer data viewer can be installed to a PC directly off the CD-ROM. The program can display, print, and query the *.shp files. This provides an opportunity for those without specialized GIS software to explore the Whitehorse Valley Surface Water Inventory databases on their own PC.

7.1.1 Directories

The top level or root directory of the CD, contains the following files, primary directories and subdirectories as shown on Table 7:

7.2 Data Layers

Data files are stored within each of the \data subdirectories, i.e. \MapInfo, \Arc, \DXF, or \e00, and are based on the data format type.

Each subdirectory contains the project data with each data type as a unique file or set of files which is often referred to as a layer or theme. Each data file(s) has been given a unique name derived from a concatenation of codes for the four parameters: data scale, geographic extent, theme, and its file type (extension). These codes are summarized in Table 8 and a few examples are given below.

Examples:

♦ Twhs_lks.tab: twenty thousand scale data of all the Whitehorse area, lakes data and in tab (MapInfo table) format.

♦ Twhs_str.shp: twenty thousand scale data of all the Whitehorse area, stream data and in shp (ArcView and ArcExplorer shapefile) format.

8. Watershed Stressors Inventory

As part of this project, a preliminary inventory of potential impacts on the City of Whitehorse water supply was conducted. These potential impacts, or stressors, consist of natural and anthropogenic activities upstream of the City’s water intake at Schwatka Lake.

The results of the watershed stressors inventory are shown on Map 3: Watershed Stressor Map which is contained in the map pocket at the back of this report.

8.1.1 Watershed Stressor Study Area

For the purposes of the watershed stressor inventory, the study area selected consisting of the Yukon River watershed upstream of the City’s water intake located at Schwatka Lake. In order to keep the scope of the inventory manageable, the study area is limited to activities as far upstream as the Tagish River. The watershed stressor inventory study area is also illustrated on Figure 1.

8.2 Stressor Types

8.2.1 Float Plane Base

This float plane base poses a risk of hydrocarbon spills related to fuel storage and aircraft refueling. This location is of particular concern because of its proximity to the City’s water intake (a distance of less than 250 m). The City currently has a Lake Waterfront Policy (1999) that states that all handing of fuel must be in compliance with Yukon Regulations. Furthermore, fueling can only occur at one site along Schwatka Lake. The City is currently in the process of updating and strengthening these policies (Natural Resources Canada 2001)

8.2.2 Giardia

Giardiasis, or “Beaver Fever” is caused by waterborne cysts. Giardia is found naturally occurring in the northern environment and is carried and transmitted by humans and animals. Giardia can cause the illness known as giardiasis, an intestinal illness which can cause nausea, anorexia, fever, and severe diarrhea. The symptoms last for several days only and the body can naturally rid itself of the parasite in one to two months. However, for individuals with weakened immune systems the body often cannot rid itself of the parasite without medical treatment. All surface water sources of drinking water are susceptible to giardia and other parasites (Minister of National Health and Welfare 1993) and therefore is a potential concern for the City of Whitehorse and its residents. The City currently samples for giardia monthly as part of its water licence requirements. Giardia is found throughout the landscape and Yukon’s watersheds and therefore, giardia cannot be mapped to a specific area and is not shown on the Watershed Stressor Map.

Gartner (20911-3ra0418.doc-05/01/01) 40 Lee Whitehorse Surface Water Inventory Users’ Guide

8.2.3 Highways

As part of the mapping, highways within 500 meters of Yukon River or a major tributaries were highlighted. These sections of highway are highlighted in red on the Watershed Stressor Map. These areas are identified as portions of the watershed that are susceptible to spills related to highway accidents. The Alaska and Klondike Highways are major transportation routes for hydrocarbon, fuels and other chemicals. 48% of the 108 kilometers of Yukon Highways within the study area are within 500 meters of the Yukon River or a major tributary.

8.2.4 Rural Residential Areas

The concern with rural residential areas is the discharge from septic systems. Specifically this would be bacteriological and nutrient related concerns. Rural residential areas are shown in dark yellow on the Watershed Stressor Map (Community Services Branch 2001). These areas are primarily clustered in two areas: 1) at the south end of the City of Whitehorse and all are perennial residences; and 2) along the east shore of Marsh Lake and consist mostly of recreational/seasonal cabins. Some of the residences in the Marsh Lake area are inhabited year round, but the number of permanent residences is unknown at this time. The relative concern with this type of development is low because of the low density and extent of the rural residential development relative to the watershed size and as well as the assimilative capacity of the Yukon River system. Less than 0.5% of the study area is developed as rural residential areas.

8.2.5 Agricultural Areas

Agricultural development within the City of Whitehorse’s immediate water supply watershed is very limited. Agricultural activities are found just east of the Golden Horn subdivision and also in the M’Clintock River valley (Community Services Branch 2001). This agriculture consists of either non-soil based agriculture (ie. greenhouses) or as low-intensity farming of feed crops such as oats or hay. Agricultural development is regulated by the Government of Yukon’s Agriculture Branch and new agricultural development is conducted through agricultural applications to the Branch. Currently 9.8 square kilometers of the study area (0.1%) is identified as agricultural land. An additional 4.1 square kilometers of new agricultural applications are being processed or developed. Agricultural lands are shown in purple on the Watershed Stressor Map.

8.2.6 Forestry

Currently there is no active commercial forestry in the Whitehorse water supply watershed study area. Prior to any commercial forestry, forestry planning areas need to be developed by DIAND Forestry. The only forestry planning areas in the Whitehorse area are in the Lubbock Valley (Little Atlin Lake) and a small area near Crag Lake. Both of these areas are outside the study area. The concern with forestry is related to increased erosion caused by deforestation and subsequent increase in sediment load in the surface water.

Gartner (20911-3ra0418.doc-05/01/01) 41 Lee Whitehorse Surface Water Inventory Users’ Guide

The Watershed Stessor Map shows areas that have been commercially harvested since 1990 (3.7 km sq.) and the areas of currently merchantable timber (Indian and Northern Affairs 2000). The merchantable timber does not imply there are any harvest plans or if harvesting the timber is feasible, it is only a generalized representation of the distribution of currently merchantable forest. Again, this is a very small portion of the watershed with only 87 km sq. (or 2.5% of the study area) being covered with currently merchantable timber. This data was provided by DIAND Forestry and is based on their preliminary timber supply analysis models.

8.2.7 Waste Sites (dumps, sewage lagoons).

Currently there are three active waste sites in the Whitehorse water supply watershed study area, these are the Mile-9 dump (in the hamlet of Mt. Lorne), the Marsh Lake dump and the Marsh Lake Sewage Lagoon. All of these facilities are operated by the Government of Yukon’s Engineering & Development Branch. The dumps are regulated under solid waste permits (Yukon Solid Waste Regulations) and the sewage lagoon has a Water Licence under the Yukon Waters Act. The concerns with these site are leachate generation from the dumps and bacterialogical and nutrient loading from the sewage lagoon. All three of these site are very small and serve very small populations relative to the size of the watershed.

8.2.8 Mines and Mineral Deposits

Mineral deposit locations are shown on the Watershed Stressor Map with the crossed hammers symbol (Indian and Northern Affairs Canada 1999). The concern with mineral deposits is increased sedimentation and erosion from the development of the deposit or metal effluent from the mining and milling of the mineral deposit. There are no active mines in the City’s watershed. There are two small open pits that were mined for copper in the late 1960’s at the south end of the City. There is only one un- mined mineral deposit in the study area, the Cowley Park copper deposit just south of the Whitehorse city limits.

8.2.9 Gravel Pits and Quarries

Gavel pits and quarries are identified as a concern due to the low potential for increased erosion and sediment generation related to development and operation of the pit or quarry. The major active gravel pits are in the City of Whitehorse near Ear Lake and McLean Lake. There are numerous current and abandoned gravel pits along the Alaska Highway as shown on the Watershed Stressor Map (Transportation Maintenance Branch, pers. comm., 2000). Presently there are no major highway development in the study area, and as such no significant work occurring in any of the current highway gravel pits.

9. Conclusions and Recommendations

9.1 Conclusions

1. Watersheds of the Whitehorse Valley have been identified and mapped at 1:20,000 scale. Thirty watershed areas have been identified. Eleven of these are closed watersheds (no surface outflow), for example Chadburn Lake complex, Copper Creek, and Porter Creek. Surface water flow is strongly controlled by the presence of meltwater channels, for example McLean Creek watershed and McIntyre Creek. 2. Updated mapping of the stream network in the Whitehorse valley has been completed at 1:20,000 scale. 3. Stream and lake attribute data has been developed, including consistent toponomy. 4. 130 lake groups have been identified in the study area consisting of 429 discrete lakes (including shallow open water wetlands). Of these,

♦ 28% of lakes in the study area are glacial kettle lakes or dead ice complex lakes;

♦ 25% of lakes are beaver dam ponds;

♦ 13% of lakes are glacial moraine lakes; and

♦ 10% of lakes are fluvial dammed lakes 5. A watershed stessor inventory of the City of Whitehorse’s surface water supply watershed has been completed. This inventory identifies potential impacts, consisting of natural and anthropogenic activities upstream of the City’s water supply intake at Schwatka Lake.

9.2 Recommendations

1. The updated stream mapping should be used for future mapping and planning exercises conducted by the City of Whitehorse. The toponomy identified as part of this project should be adopted by the City and other agencies to standardize reference to surface water features.

2. Further fieldwork should be conducted to determine stream locations in areas of poor coverage. Areas requiring significant work include the upper reaches of Cowley Creek (Dugdale Creek), creeks flowing from Mt. Lorne, and the mid and upper reaches of Croucher Creek.

3. The streams and lakes identified in this study should be assigned Watershed Codes when the Dept. of Fisheries and Oceans Canada have completed and implemented their Watershed Code system.

4. In order to address the watershed stressors identified in this project, it is recommended that a Wastershed Stressor Assessment be conducted to determine the need for Stressor Management Strategies in order to protect the City’s water supply.
