EXECUTIVE SUMMARY
This report documents the findings of the Dawson Creek Limited Watershed Assessment conducted by Hemmera Envirochem Inc, (“Hemmera”) on behalf of the Dawson Creek Watershed Society. The Dawson Creek Watershed is located near the City of Dawson Creek, in northeastern BC. The watershed supports a number of land uses and economic activities including: urban development, agriculture, oil and gas exploration, and recreation and tourism activities. Human development activities in the watershed have altered Dawson Creek. The Dawson Creek drainage basin covers an area of 274 km2, has a mainstem length of 43.5 km and includes several tributaries (Ski Hill Creek, South Dawson Creek, Frondizi Creek, plus many un- named tributaries). The watershed drains from west to east, through the City of Dawson Creek and empties into the Pouce Coupe River.
The purpose of the watershed assessment is to develop an understanding of the baseline watershed conditions. It is intended that this information will be used to assist the Dawson Creek Watershed Society in developing strategies for restoring and managing the watershed. The assessment methodology involved research of existing baseline information; compilation of baseline information onto GIS maps; discussion of baseline conditions and identification of preliminary issues and recommendations.
Based on the limited watershed assessment, the following key issues were identified:
• Barrier to fish passage at Snake Pit Road (Rolla Road) Crossing;
• Water quality concerns (i.e., coliform bacteria, water temperature and dissolved oxygen), and potential leachate issues near the “old” Dawson Creek Landfill;
• Low water flow potentially linked to water licenses within the watershed; and,
• Requirement for further studies to confirm fish presence/absence upstream of the Rolla Road crossing.
The findings of the Limited Watershed Assessment (LWA) may be used in a number of ways to address land and water use issues that may potentially challenge ecosystem functions within the
Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - ii - January 2006
Dawson Creek Watershed. The following are some of the ways that the findings from the LWA could be used.
• Develop “Issue Specific” Action Plans – The results of the LWA are not confirmed or supported by field studies. As such, an appropriate use of the findings of the LWA would be to undertake field level studies to confirm one or more of the key issues identified above and collect information to support a better problem definition of such issues. This information would support the development of issue specific action plans.
• Develop a Watershed Management Plan – The findings of the report could be used as a foundation document that supports a process to develop a watershed management plan (WMP). Such a plan, would likely be developed in collaboration with key stakeholders with an interest in the health of the watershed and would include long term goals and objectives for protection and enhancement of the watershed. The WMP would support, guide and prioritize issue specific action plans discussed above.
The advantage of focusing on issue specific action plans is that it allows for immediate action on a fairly well defined set of issues and potentially provides for some early successes for the group. Having some early success is important in building support for longer term watershed planning and management activities. In addition, the collaboration required between stakeholders in advancing issue specific action plans can help to build working relationships necessary for developing a WMP and the structure necessary for its long term implementation.
The disadvantage of this approach, is that the issue specific action plans would not be guided by a long term vision for the watershed. At the same time, it is possible to initiate the development of a WMP after the development of issue specific action plans and there are advantage to doing so as outlined above.
Regardless of what approach is decided upon, it is essential that the decision-making process involve all stakeholders with an interest in the watershed. This will ensure that decisions made, regarding next steps are supported by stakeholders with an interest in the long-term health of the watershed.
Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - iii - January 2006
As such, the recommended next steps are to organize stakeholder consultation meetings to decide how the findings of the LWA are best applied in the short term, establish an appropriate scope of work for 2006 and discuss potential funding sources to support the 2006 workplan.

1.0 INTRODUCTION
This report documents the findings of the Dawson Creek Limited Watershed Assessment conducted by Hemmera Envirochem Inc, (“Hemmera”) on behalf of the Dawson Creek Watershed Society. The Dawson Creek Watershed is located near the City of Dawson Creek, in northeastern BC, as shown on Figure 1. The watershed supports a number of land uses and economic activities including: urban development, agriculture, oil and gas exploration, and recreation and tourism activities. Human development activities in the watershed have altered Dawson Creek. The Dawson Creek drainage basin covers an area of 274 km2, has a mainstem length of 43.5 km and includes several tributaries (Ski Hill Creek, South Dawson Creek, Frondizi Creek, plus many un-named tributaries). The watershed drains from west to east, through the City of Dawson Creek and empties into the Pouce Coupe River.
Based on background information provided, the Dawson Creek Watershed is a relatively disturbed watershed as a result of a variety of historical activities. Particular concerns within the watershed include: urban impact from the City of Dawson Creek; past landfill activities adjacent to the stream (the landfill is currently deactivated); adjacent agricultural land use in the headwaters; and stream disturbance and bank stability issues due to channel re-routing.
The Dawson Creek Watershed Society is a local stewardship group tasked with the goal of improving, and hopefully rehabilitating, the City’s namesake creek. The Society has currently received funding from the City of Dawson Creek start this process.
1.1 PURPOSE
The purpose of the watershed assessment is to develop an understanding of the baseline watershed conditions. It is intended that this information will be used to assist the Dawson Creek Watershed Society in developing strategies for restoring and managing the watershed. Given the budget limitations, a Limited Watershed Assessment has been conducted for the watershed, that involved collection of specific baseline information, within the current funding limit.
Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - 2 - January 2006
It is anticipated that the results of the Limited Watershed Assessment will be used to develop a Watershed Management Plan for the Dawson Creek watershed. The relationship of these two studies is discussed further in Section 5.0 – Next Steps.
1.2 LIMITED WATERSHED ASSESSMENT PROCEDURE
The methodology for conducting the Limited Watershed Assessment for the Dawson Creek watershed is outlined below according to the following tasks:
• Information collection;
• Mapping; and
• Reporting.
1.2.1 Information Collection
One of the first steps of the watershed assessment consists of gathering all available baseline information on the watershed, including data documenting resource uses within the watershed. Baseline information includes physical watershed characteristics, biological resources, land use, infrastructure and water resources in the watershed. The following information was acquired: airphotos, land use maps, digital base maps, water licence information, climate/hydrology data and any available water quality data. In addition, historical stream/fisheries information was researched (including anecdotal data).
The information sources are listed in the next section, Section 2.0 – Information Sources.
1.2.2 Mapping
The data collected during the information collection phase described above were compiled and mapped on digital GIS maps, as shown on Figures 2 through 8.
The airphotos and digital topographic maps were used to classify stream reaches within the Dawson Creek watershed through a desktop stream reach mapping exercise, shown on Figure 8. A desktop sediment source survey was also carried out to identify potential large sediment sources within the watershed (Figure 7).
Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - 3 - January 2006
Reach Break Methodology A reach is a channel segment with relatively repetitious and homogenous sequence of physical processes and habitat types (e.g., homogenous slope, discharge, habitat, channel type, and riparian features). Lakes and wetlands are also considered reaches for the purpose of planning. A reach number is the number given to individual reaches.
Reach breaks were established through map and aerial photo interpretation. Topographic maps, at a 1:20,000 scale, were used for the initial reach break analysis, and initial reach breaks were placed where the changes were observed in:
• Hydrological regime - such as where large tributaries enter;
• Gradient - including slopes reaching greater than 20%;
• Channel meander; and,
• Channel confinement or obvious channelling.
Orthophotos of the watershed from 1996 (black and white, 1:40,000 scale) were then reviewed to confirm or revise initial reach break selection. Changes in physical features of the creek and adjacent land areas, such as channel confinement and abrupt changes in adjacent vegetation and land use, were used to determine and confirm the reach breaks.
Reach breaks are mapped on Figure 8, with detailed reach break information contained in Appendix B (Tables B1 and B2).
Sediment Source Mapping Methodology Sediment sources were identified using 1996 black and white aerial photographs at a scale of 1:40,000. Small, un-vegetated areas along the streambed, which appear to have the potential to contribute sediment to the stream are marked with SS as shown on Figure 7 and assigned a number. A description of the sediment source is provided in Tables B1 and B2, in as much detail as possible, given the scale of the photographs.

1.2.3 Reporting
The Limited Watershed Assessment report contained herein presents and provides discussion on the aforementioned data and compiled GIS maps. The report also provides recommendations for building on this baseline information and moving forward towards developing a watershed management plan and eventually towards watershed rehabilitation. These next steps are discussed further in Section 5.0 – Next Steps.

3.0 EXISTING ENVIRONMENTAL CONDITIONS
This section presents and discusses available baseline information collected for the Dawson Creek Watershed.
3.1 PHYSICAL SETTING
The mainstem of Dawson Creek runs through the City of Dawson Creek, located in northeastern BC. The mainstem of Dawson Creek is approximately 43.5 kms long, starting from the Kitskatinaw River – Dawson Creek watershed divide and flowing east towards the Pouce Coupe River (Figure 1 and Figure 2).
The entire Dawson Creek Watershed covers approximately 274 km2 and can be divided into three main (sub) watersheds, as shown on Figure 2 and listed below:
• Dawson Creek Main Watershed;
• Dawson Creek South Watershed;
• Ski Hill Creek Watershed.
Within these watersheds, additional sub-basins have been defined as shown on Figure 3 and listed below in Table 2. The sub-basins were defined where third order streams become fourth order streams or higher.

Reach breaks for the entire Dawson Creek Watershed are also shown on Figure 8, which can be cross-referenced with Tables B1 and B2, located in Appendix B, for further stream reach and sub-basin information, including the elevation, length, slope and stream order of each tributary, reach and sub-basin. The following sections provide a general overview of the general physical watershed characteristics, discussed by the three watersheds: Dawson Creek Main Watershed; South Dawson Creek Watershed; Ski Hill Creek Watershed.
3.1.1 Dawson Creek Main Watershed
The Dawson Creek Main Watershed is located in the northern part of the Dawson Creek Watershed, as shown on Figure 2 and Figure 3. The main stem flows west to east with an average stream gradient of 0.3% in the main valley, with slightly steeper gradients in the upper
Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - 9 - January 2006
sub-basins (average gradient approximately 2 – 3 %). The overall aspect of the Dawson Creek Main Watershed is to the west.
As shown on Figure 8, the mainstem of Dawson Creek is divided into 11 reaches starting at the confluence with Pouce Coupe and ending in the Dawson Creek Main West sub-basin at the western edge of the Dawson Creek / Kiskatinaw watershed divide. Reaches 1-4 were classified predominantly based on changes in land use, as Dawson Creek meanders extensively through the developed parts of the City of Dawson Creek. The divide between reach 4 and 5 occurs at the point where South Dawson Creek (a 5th order stream), enters the mainstem, changing the hydrology of the creek. Reaches 5 through 8 were assigned based on land-use changes and stream meander patterns. The divide between reach 8 and 9 occurs at the point where the North Arm and Dawson Creek Main West Sub-basins come together. Reaches through the North Arm and DC Main West were divided into four and three reaches respectively, based primarily on hydrological changes.
3.1.2 Dawson Creek South Watershed
The Dawson Creek South Watershed is located in the southeastern part of the Dawson Creek drainage basin, as shown on Figure 2 and Figure 3. The main stem flows west to northeast with an average gradient of 1 – 2 % on the mainstem, with steeper gradients (5-10%) in the upper sub- basins that end along the Dawson Creek/Kitskatinaw River watershed divide located along the western boundary of the watershed. The overall aspect of the South Dawson Creek Watershed is to the north.
As shown on Figure 8, the breaks between the four reaches of Dawson Creek South were primarily located where large tributaries converge; areas of expected hydrological change. The larger tributaries were also divided into reaches within the Dawson Creek South, Frondizi Creek, ST10, ST10F and ST10G sub-basins. Within the sub-basins of the southwest side of the watershed, reach breaks were based largely on gradient for areas at the southern edge of the watershed divide where the topography is steep, and on hydrological and land-use changes otherwise.
Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - 10 - January 2006
3.1.3 Ski Hill Creek Watershed
The Ski Hill Creek Watershed is located in the southern part of the Dawson Creek drainage basin, as shown on Figure 2 and Figure 3. The main stem flows south to north with an average stream gradient of 3% with steeper gradients in the headwaters (10-20%). This is the steepest watershed in the drainage basin. The local Bear Mountain Ski Hill is located near the top of this northern aspect watershed.
The mainstem of Ski Hill Creek (‘Tributary 8’ to the Dawson Creek mainstem) was divided into three reaches based primarily on land-use changes along the stream. One of the main tributaries to this creek (T8F) was divided into four reaches. The breaks between these reaches were based on both hydrological and gradient changes.
3.2 CHANNEL CHARACTERISTICS
3.2.1 Channel Morphology
A site visit was outside the scope of the Limited Watershed Assessment. However, based on the 1:40,000 airphotos, topographic maps, and photos from the 1999 Water Quality Program, the following general comments on channel morphology within the Dawson Creek drainage basin can be made.
Although the different reaches within the Dawson Creek Watershed may have differing morphological characteristics, the majority of the streams within the drainage basin can be classified generally as C3 stream type, based on the Rosgen stream classification system.
C3 streams generally meet the following criteria:
Table 3: C3 Stream Type Delineative Criteria1
Landform/soils: Broad alluvial and glaciated valleys, Holocene terraces generally present. Soils are glacial deposition and alluvium. Channel materials: Predominantly cobble with lesser amounts of gravel and sand. Banks are finer in material size than channel bed material. Slope range: <0.02 (< 2%) Entrenchment Ratio: >2.2 Width/depth ratio: >12 Sinuosity: >1.2

Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - 11 - January 2006
3.2.2 Sediment Source Survey
As shown on Figure 7 and described in Appendix B (Tables B1 and B2), the main sediment sources consist of large unvegetated areas (by anthropogenic activities) adjacent to the creek and include the landfill area (SS1), as well as several main road crossings, and altered areas of riparian vegetation.
Although also influenced by anthropogenic activities, unvegetated stream banks that border on agricultural areas were not labeled as sediment sources on the map, because they were not considered point sources and are numerous in the watershed where they border considerable sections of the stream and tributaries. Even though these agricultural fields were not marked as sediment sources on the map, it should be noted that fields may contribute to sediment entering Dawson Creek. Following site specific assessment of potential sediment sources, measures to minimize this source (establishment of vegetation buffers or fencing) should be considered in any sediment reduction plan, if warranted.
Field observations of potential sediment sources (such as bare soil and bank erosion) were measured as part of the 1999 Water Quality Program with the following findings, “Throughout the creek we have seen very little bare soil or bank erosion.” The water quality program findings are discussed in more detail in Section 3.6.3.
3.3 CLIMATE
An Environment Canada climate station (Dawson Creek A #1182285) is located within the Dawson Creek watershed, as shown on Figure 6. The 1971 to 2000 climate normals for this station are presented in Table A1 located in Appendix A. The yearly average temperature is 1.6 C, with the highest temperatures occurring in July and August (average 14 to 15 C, extreme maximum 34.5 C recorded on August 9, 1981), and the lowest temperatures occurring in December and January (average –12 to –15 C, extreme minimum –49.2 C recorded on December 29, 1992). The annual rainfall is 325.6 mm, with the wettest months occurring May through September, and the driest months occurring in September and October. The annual snowfall is 174 cm, with the largest snowfalls typically occurring in December and January.

3.4 HYDROLOGY
Although there are no active flow metering stations within the Dawson Creek watershed, there were two historical Water Survey of Canada stations located in the watershed in the past 20 years, see Table 4 below and Figure 7.
Table 4: Water Survey of Canada Hydrology Stations
Station Name Station # Basin Period Years of Comments Area of Record (km2) Record South Dawson Creek at the 07FD016 85.2 1981-1985 5 Seasonal flow only Mouth Dawson Creek above South 07FD015 116 1981-1995 16 Seasonal flow only Dawson Creek
When active, these hydrology stations recorded seasonal flow only (stream flow from April through to October (non-winter conditions)).
The South Dawson Creek hydrology station has too short of a record (5 years) to analyze the data with any confidence. However, the data shows a trend that suggests the highest flows occur through May, June and July (freshet due to snowmelt), with flows dropping considerably in August, September and October (see Table A2 located in Appendix A).
The Dawson Creek hydrology station, with 16 years of record, shows a similar trend with the highest flow occurring through May, June and July (average daily flow between 0.2 m3/s and 0.4 m3/s). The highest daily flow was recorded to be 35.8 m3/s, which occurred on June 12, 1990, and the highest monthly mean flow was recorded to be 3.82 m3/s for June. The lowest flow typically occurs in late summer / early fall, where it is not uncommon for the flow rate to drop to zero. During these times of zero flow, there is still water in the creek, however very little to no measureable flow, (see Table A3 in Appendix A).
The flow regime within the watershed is natural, meaning that the flow is not regulated by a dam, reservoir or other water storage structure. The City of Dawson Creek domestic water
Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - 13 - January 2006
supply comes from the Kitskatinaw River watershed, which is to the west of the Dawson Creek drainage basin. However, there are several water licences within the watershed that may influence flow rates within the creek. Water licences are discussed further in Section 3.5 – Land Use and Resource Use.
3.5 LAND USE AND RESOURCE USE
This section describes the land use and resource use of the watershed by sub-basin. The information was collected through a review of regional planning studies, resource and industry websites and databases, and government resources. The information was compiled and mapped using GIS, as shown on Figures 2 through 7.
3.5.1 Dawson Creek Main Watershed
The Dawson Creek Main Watershed includes the majority of the City of Dawson Creek municipality. Dawson Creek runs through an urban corridor within the municipality and is also subject to storm water and wastewater effluent inputs. Municipal effluent data is discussed further in Section 3.6.3 Water Quality.
Outside of the city limits, the land use is classified as being within the Agricultural Land Reserve (ALR land), (Figure 5). The ALR is provincial zone in which agriculture is recognized as the priority use and is encouraged, and other land uses are controlled (ALC 2004). Local and regional governments, as well as other provincial agencies, are expected to plan in accordance with the provincial policy of preserving agricultural land. The Agricultural Land Commission Act sets the legislative framework for the establishment and administration of the agricultural land preservation program. This legislation takes precedence over, but does not replace other legislation and bylaws that may apply to the land. The ALR is administered in favour of agriculture by the BC Provincial Agricultural Land Commission (ALC), which is an independent provincial agency.
A small area of Ministry of Forest Grazing tenure exists in the western corner of the North Arm sub-basin (Figure 4). Grazing tenures can be defined as the use and control of range land (crown land) for cattle grazing purposes.
Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - 14 - January 2006
Land use, as designated in the 1986 Peace River Regional District Official Community Plan (OCP), is shown on Figure 6. Although somewhat dated, this is the most recent OCP for the watershed.2 Land use in this watershed is primarily agricultural (approximately 80 % of the Dawson Creek Main Watershed is within the ALR) and municipal (the majority of the City of Dawson Creek city limits fall within the Dawson Creek Main Watershed). There are two main industrial areas in the Dawson Creek main watershed: one located northeast of the city limits along Highway 97; and one located northwest of the city limits (landfill) (shown as red areas on Figure 6). In addition, there are two industries within the municipal limits that are in close proximity to Dawson Creek: Emporium Investments (a wood processing facility) and Lawrence’s Abattoir (both shown on Figure 6).
The landfill was closed between 2000 and 2002. Waste from the Municipality of Dawson Creek is now disposed of in a landfill located in the Besboro farming community, located outside of the municipality3. Closure of the landfill followed a detailed Closure Plan, which involved covering the landfill with an intermediate cover, followed by a final cover cap of clay, 2 to 3 ft thick4. The Closure Plan also prescribed annual groundwater monitoring (groundwater water quality results are discussed in Section 3.6.3 Water Quality).
There are 10 water licenses in the Dawson Creek Main Watershed, with 5 licenses located on the mainstem, and the remaining 5 licenses located in the North Arm sub-basin (Figure 3).
There are 19 gas exploration wells located in the Dawson Creek Main Watershed, with 15 of the wells located in the headwaters of the DC Main West and North Arm sub-basins (Figure 3).
3.5.2 Dawson Creek South Watershed
The Dawson Creek South Watershed includes a small portion of the City of Dawson Creek municipality near the confluence with Dawson Creek mainstem. Outside of the city limits, the land use is primarily classified as being within the Agricultural Land Reserve (ALR land), (Figure 5).

Ministry of Forest Grazing tenure exists in the southwestern corner of the Dawson Creek South sub-basin, located outside of the ALR and along the Dawson Creek / Kitskatinaw River watershed divide (Figure 4).
Land use, as designated in the 1986 Peace River Regional District OCP, is shown on Figure 6. Land use is primarily municipal, rural and small holdings – agriculture, with smaller areas designated as gravel resource (along the eastern boundary of this watershed) and public recreation (along the western boundary of this watershed (the Dawson Creek/Kitskatinaw River watershed divide)).
There are 13 water licenses in the Dawson Creek South Watershed, with 7 licenses located on the mainstem (Figure 3). Also shown on Figure 3, there are 10 gas exploration wells located in the Dawson Creek South Watershed, with six of the wells located near the western boundary of the watershed, along Bear Mountain ridge.
3.5.3 Ski Hill Creek Watershed
The Ski Hill Creek Watershed includes a portion of the City of Dawson Creek municipality at the northern portion of the watershed, near the confluence with the main stem of Dawson Creek. Outside of the city limits, the land use is classified as being within the Agricultural Land Reserve (ALR land), (Figure 5). As well, the following land-use designations as per the OCP apply (Figure 6): small agricultural holdings; rural residential; public use or public recreation (the Bear Mountain Ski Hill; and future rural residential
No Ministry of Forest grazing tenures exist in this watershed (Figure 4).
There are 6 water licenses in the Ski Hill Creek Watershed, with 4 licenses located on the mainstem (Figure 3). Also shown on Figure 3, there are 2 gas exploration wells located in the Ski Hill Creek Watershed.

3.6 BIOLOGICAL RESOURCES
3.6.1 Fish Presence
According to the Freshwater Fisheries Society of BC Fish Wizard database, fish species found within the Dawson Creek watershed include the following:
• Brook Stickleback (Culaea inconstans)
• Burbot (Lota lota)
• Lake Chub (Couesius plumbeus)
• Lake Whitefish (Coregonus clupeaformis)
• Longnose Sucker (Catostomus catostomus)
• Minnow (General) (Hybognathus)
• Redside Shiner (Richardsonius balteatus)
• Sucker (General) (Notropis)
• White Sucker (Catostomus commersonii)
In addition to data listed in the Freshwater Fisheries Society of BC Fish Wizard database, a 1997 fisheries field survey conducted on Dawson Creek (Peace Fisheries Field Report (Harvey, 1997)), documents fish observed in Dawson Creek. As part of the 1997 study, a one-day sampling program was conducted at two sampling locations:
• Rolla Road: just downstream of the point where Rolla road crosses the creek, which is located east of the town of Dawson Creek, and just east of the rail crossing which marks the break between reaches 1 and 2 on the Dawson Creek mainstem (see Figure 7).
• Landfill Site: downstream of the landfill (see Figure 7).
A total of 110 fish were captured and identified at the Rolla Road site: 29 longnose suckers, 10 white suckers; 3 burbot and 68 lake chub. The sampling program conducted at the upstream
Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - 17 - January 2006
Dawson Creek station located at the landfill site did not result in any fish catches. It is important to note that this field survey was limited to a one-day field visit at each site. A copy of the 1997 fisheries report is included in Appendix C.
According to the Fish Wizard database, a 3.8 metre diametre, 38 metre long culvert exists on Dawson Creek and is considered a barrier to fish passage, due to high velocities and the outfall drop. It is assumed that this barrier is at the Rolla road crossing, which is noted to be an impassable barrier in the 1997 fisheries field report (Harvey, 1997).
Based on anecdotal information, a “long nose sucker” was observed in “Rotary Lake” in 20025. “Rotary Lake” is located near the northern limits of the City of Dawson Creek, approximately 5 kms upstream of the “old” municipal landfill site. Fingerlings were also observed throughout Dawson Creek during the 1999 Water Quality Program.
As discussed previously, Dawson Creek flows into the Pouce Coupe River. Therefore, a search of fish species observed in the Pouce Coupe River was also conducted, as these species may be of interest if rehabilitation activities within Dawson Creek are planned.
In addition to the fish species noted on the Fish Wizard database for Dawson Creek, five additional species are also found in the Pouce Coupe River:
• Flathead Chub, (Platygobio gracilis)
• Longnose Dace, (Rhinichthys cataractae)
• Northern Pike, (Esox lucius Linnaeus)
• Troutperch, (Percopsis omiscomaycus)
• Yellow Perch (Perca flavescens)
Overall, the information collected, including an informal web search for information relating to fishing opportunities within the Dawson Creek area, indicates that Dawson Creek and its tributaries do not currently support large or commercially viable fish populations. However fish

species have been recorded within the watershed and there may be potential to increase fish presence within the watershed through rehabilitation measures.
3.6.2 Vegetation
A detailed vegetation study was not conducted as part of this limited watershed assessment. The watershed is located in the “Boreal White and Black Spruce” biogeoclimatic zone6. Biogeoclimatic zones are large geographic zones that share a similar climate within the province. There are 14 biogeoclimatic zones in the province.
Based on a review of the 1:40,000 airphotos, the majority of the watershed consists of primarily agricultural land. There is very little forest cover within the Dawson Creek watershed.
3.6.3 Water Quality
Water quality information for the Dawson Creek watershed is available from three different studies, however much of the data is limited in its scope. The programs include: the 1999 Dawson Creek Water Quality Program; the Dawson Creek Landfill Groundwater Monitoring Program; and the City of Dawson Creek water quality program.
3.6.3.1 1999 Dawson Creek Water Quality Program
A one-year water quality program was conducted in 1999 on the mainstem of Dawson Creek as part of the Dawson Creek Restoration Project. The water quality information presented in this section has been summarized from the following report:
Water Quality Program Final Report – 1999. Prepared for the Dawson Creek Restoration Project, the Peace Liard Science Council of BC, Youth Services Canada, and the City of Dawson Creek.
The program involved collecting water quality and stream health information at 10 sites in the Dawson Creek watershed, as shown on Figure 7. Photos of the sites are included in Appendix D. The water quality program looked at the following parameters:

• Bare soil and bank erosion
• Soil and water odor
• Water appearance and turbidity
• Coliform Bacteria, Dissolved Oxygen, Biochemical Oxygen Demand (BOD 5- day)
• Nitrate, pH and Phosphate
• Temperature
The program was limited to one sample collected at each site for semi-quantitative analysis, with only one of the ten samples submitted for major ions and total metals quantitative analysis at an analytical lab. For comparison purposes, tests were also run on “control sites,” that included: municipal tap water,7 rainwater cistern water and local dugout water (near Bonanza, Alberta).
The sampling sites are described below in Table 5, highlighting any “poor” or “fair” water quality ratings based on the 1999 report (if the parameters are not noted below, then they were considered “good” or “excellent” during the 1999 program).

Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - 21 - January 2006
The 1999 - Water Quality Program Final Report identified the following “Problem Areas and Recommendations:”
1. Coliform Bacteria – identify potential sources and perform quantitative tests to establish severity of threat;
2. Dawson Creek Landfill – phosphate tests indicate landfill leachate entering the creek. Perform more tests to identify contaminants;
3. Refuse and Garbage in the Creek – more clean up and public education required to keep the creek refuse-free;
4. Testing – testing with the GREEN kits should continue next year. pH monitoring and BOD testing should be emphasized to monitor the life bearing capacity of the stream;
5. Timing – testing should begin right after snow melt, with another batch in mid summer and then late fall;
6. Additional equipment to conduct quantitative sampling.
Unfortunately, funding for the water quality program ended in 1999/2000 and the program was discontinued.
3.6.3.2 Dawson Creek Landfill Groundwater Monitoring
As discussed in Section 3.5 Land Use and Resource Use, the old Dawson Creek landfill was closed between 2000 and 2002, as per a detailed Closure Plan. The Closure Plan prescribed annual groundwater monitoring. Water quality results from the 2004 groundwater monitoring program are included in Appendix E. Based on the 2004 results (Seacor 2005), exceedences of the BC Contaminated Sites Regulation (CSR) drinking water standards for magnesium, manganese, chloride and sulphate were observed; while exceedences of CSR Aquatic Life standard for ammonia and sulphate were observed.

3.6.3.3 City of Dawson Creek Water Quality Monitoring Program
The City of Dawson Creek regularly monitors the wastewater effluent water quality from the municipality’s wastewater treatment lagoons. Monthly lagoon outfall water quality data from 1996 to 2005 is contained in Appendix F and includes data for several parameters (temperature, pH, conductivity, dissolved oxygen, fecal and total coliforms, total suspended solids, total phosphorous, nitrite, ammonia, BOD5 and E.Coli).
In addition, the City of Dawson Creek carried out a receiving water quality monitoring program for the Ministry of Environment in 1999 and 2001 at four sample locations:
• Dawson Creek – Upstream of dump and landfill;
• Dawson Creek – At Rolla Road Crossing;
• Pouce Coupe River – At Briar Ridge Road Crossing (upstream of Dawson Creek/Pouce Coupe River confluence); and,
• Pouce Coupe River – At Highway 49 (downstream of Dawson Creek/Pouce Coupe River confluence).
The data from this program is also contained in Appendix F. A sketch map showing the locations of the lagoon effluent and receiving water quality monitoring programs is also included in Appendix F. A detailed analysis of the water quality results of these two studies was outside the scope of the Dawson Creek Limited Watershed Assessment.
Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - 23 - January 2006
4.0 PRELIMINARY ISSUES AND RECOMMENDATIONS
Based on the limited watershed assessment, the following key issues were identified.
1. Fish Passage Barrier – Snake Pit Road (Rolla Road) Crossing As stated in Section 3.6.1, a 3.8 metre diametre, 38 metre long culvert is located near the mouth of Dawson Creek. Based on the background information reviewed, the culvert is considered a full barrier to fish, due to high velocities and the height of the outfall drop. It is assumed that this barrier is at the Rolla road crossing, which is noted to be an impassable barrier in the 1997 fisheries field report (Harvey, 1997).
If connectivity to the Pouce Coupe River is deemed important for rehabilitation of the watershed and to increase fish populations within the watershed, it may be worthwhile to conduct a feasibility study to improve fish access through these culverts. Fish passage can be improved through the installation of baffles within the culvert (decrease water velocities) and improvements to the culvert outfall (create a step-pool outlet, breaking up the height drop and improving fish access).
Recommendation: Conduct a feasibility study to improve fish access through these culverts.
2. Water Quality Based on the findings from the 1999 Water Quality Program, as well as on the review of other background information in the watershed, issues relating to water quality are outlined below:
○ Coliform Bacteria: During the 1999 Water Quality Program, high coliform bacteria counts were found at many sites, but not all. It is important to note that the 1999 tests were not quantitative (the tests indicated “< or >200 colonies/100ml”).
○ Dawson Creek Landfill: Phosphate tests from the 1999 Water Quality Program indicated the potential for landfill leachate entering the creek.
Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - 24 - January 2006
Since the water quality program was been conducted, the landfill has been closed and it is believed that additional reports exist on the status on the landfill closure that may also include additional water quality monitoring results.
○ Water Temperature: In the 1999 Water Quality Program Final Report, “temperature change” is presented. The overall temperature change findings are that “very little temperature change along the length of the creek indicates low thermal pollution entering the creek.” Although this finding is informative, it does not provide information on the overall temperature of the creek. In the 1997 fish survey, the water temperature at the Rolla road crossing station was 17.5 C, and the water temperature at the Municipal Landfill site was 18 C. These are relatively high water temperatures.
○ High water temperatures can make water unsuitable for fish presence and also influence dissolved oxygen levels. The higher the water temperature, the less capacity the water has to hold dissolved oxygen (dissolved oxygen is a key requirement for fish). Interestingly, in the 1999 Water Quality Program Final Report, “moderate levels of dissolved oxygen were found throughout the test area. These levels should still be enough to support a fish population.” However, it is important to note that this finding was based on limited field data.
Recommendations: ○ Identify potential sources of fecal coliform bacteria and perform quantitative tests to establish severity of threat.
○ Review Dawson Creek Landfill closure and monitoring reports (available from the Peace River Regional District) to determine if water quality issues exist in the creek due to the landfill, and if future water quality testing relating to potential leachate impacts is warranted.
Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - 25 - January 2006
○ Review City of Dawson Creek water quality data to determine if water quality issues exist in the creek due to storm water and/or wastewater effluent, and if future water quality testing relating to effluent impacts is warranted.
○ Since limited data exists on water temperature and dissolved oxygen within the creek, it is recommended that additional field data be collected to determine if this is a limiting factor for watershed restoration.
○ Any additional water quality field tests should begin from freshet (snow melt) through to late fall. A variety of water quality testing programs are possible including relatively inexpensive temperature data loggers and community run manual sampling programs.
3. Water flow Based on a review of the data from the historic hydrology stations and in discussions with the Dawson Creek Watershed Society, low flow typically occurs in late summer / early fall, where it is not uncommon for the flow rate to drop to zero. During these times of zero flow, there is still water in the creek, however very little to no measurable flow.
As shown on Figure 3, a total of 29 water licenses were identified in the Dawson Creek Watershed as part of the compilation and mapping component of the Limited Watershed Assessment. It is important to note that low water flow and lack of riparian vegetation (lack of shading) influence water temperature.
Recommendation: Additional research be conducted on the 29 water licenses to determine their permitted withdrawal rates; whether the licences are active or inactive; and, their actual withdrawal rates. This information will help determine whether water extraction (and the resulting creek flow rate) is a limiting factor for watershed restoration.
4. Fish Presence A limited fish sampling program was conducted in 1997 indicating fish presence downstream of the Rolla Road crossing and no fish were observed at the upstream
Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - 26 - January 2006
“old” municipal landfill sampling sites. During the 1999 Water Quality Program, fingerlings were observed throughout the creek.
Recommendation: It is recommended that a reconnaissance level fish habitat and fish survey be conducted along the Dawson Creek mainstem and South Dawson Creek to confirm in the field fish habitat and fish presence.
5. Land Use and Best Management Practices The Dawson Creek Watershed consists of three main land use activities including urban development (Municipality of Dawson Creek), agriculture, and oil and gas exploration.
The 1999 Water Quality Program identified refuse and garbage in the creek, particularly through the municipality and recommended that more clean up and public education is required to keep the creek refuse-free. Oil and gas exploration, as well as agricultural activities, can also impact the health of the watershed. While such land use activities can potentially challenge the health of the watershed, very little is known about exactly how such activities might impact the watershed, how significant the impacts are or what parts of the watershed are most impacted by specific land use activities.
At the same time, it is known that there are a number of tools (e.g., sector specific best management practices, funding for some stewardship initiatives etc.) that could be used to minimize the impact of land use activities on the health of the watershed. Additional work in better understanding the specific extent and nature of land use impacts on the watershed would assist in helping to identify the stewardship tools that are most appropriate for the Dawson Creek. Such work would also help to ensure that any processes established to develop and implement watershed management initiatives have representation from the sectors and interest groups that are active in the watershed.
Recommendation: Additional work be undertaken to define potential water quality challenges to watershed health associated with existing land uses in the watershed. This work could support the identification and implementation of
Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - 27 - January 2006
stewardship practices to minimize the impacts of specific existing land use activities as well as initiatives to address historic land use impacts (i.e, enhancement/restoration activities). The Dawson Creek Land and Resource Management Plan (British Columbia 1999) should be reviewed to determine if there are opportunities to work with the Ministry of Environment in the designation of priority watersheds, best management practices and monitoring.
Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - 28 - January 2006
5.0 NEXT STEPS
The results of the Limited Watershed Assessment can be used in a number of ways to help address existing and potential challenges to the health of the Dawson Creek Watershed including:
• Guiding the development of issue specific action plans or workplans to address some or all of the issues identified in this Limited Watershed Assessment: and
• Supporting the development of a full Watershed Management Plan for the Dawson Creek Watershed.
With respect to using the findings of this report to develop issue specific action plans, this section of the LWA outlines specific next steps to be taken to finalize the LWA and begin developing action plans. In the case, of using the findings of the LWA to facilitate development of a full Watershed Management Plan this section provides some generic information on the process of developing watershed management plans.
5.1 DEVELOPING ISSUE SPECIFIC ACTION PLANS
Several issues, that potentially challenge the health of the watershed, were identified in Section 4.0 – Preliminary Issues and Recommendations of this report. Along with an identification of the issues, Section 4.0 contains recommendations with respect to how these issues can be addressed. These recommendations included both additional desktop research, as well as additional field studies as follows:
Desktop research:
• Design options for the Rolla Road culvert;
• Research landfill closure reports, with respect to water quality;
• Review City of Dawson Creek water quality data;
• Research details on water licences within the watershed;
Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - 29 - January 2006
• Research more detailed information on existing land use and identify relevant best management practices (e.g., urban, agricultural, oil and gas etc.);
• Any additional studies that come out of stakeholder consultation meetings.
Field Studies:
• Additional water quality testing (fecal coliform, water temperature, and dissolved oxygen);
• Fish sampling program and stream reach mapping; plus,
• Any additional studies that come out of stakeholder consultation meetings.
As part of developing issue specific action plans, it will be important to solicit stakeholder input. As such, it is suggested that a workshop be undertaken to discuss the findings of the Draft LWA and obtain additional input from stakeholders. Input from stakeholders, additional information on specific watershed issues, can be incorporated into the final LWA. Such input can also be used to guide efforts to develop issue specific action plans and set priorities among issues.
5.2 DEVELOPING A WATERSHED MANAGEMENT PLAN
The results of the LWA, in addition to supporting action on specific issues potentially challenging the health of the watershed, can also be used to support the development of a watershed management plan (WMP). This section provides some background information on the content of WMPs and the process that can be used to develop and implement them.
5.2.1 Definition
A WMP is a document that guides the long-term management of land and water interactions to protect the health of the watershed ecosystem, recommends how water resources are to be protected and improved as land uses and activities in the watershed change.
Watershed management plans are typically developed for three different management purposes, each with a slightly different focus:
• Resource Management: Managing watershed resources and environmental features (i.e. conservation of aquatic habitat);
Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - 30 - January 2006
• Land Management: Managing land use and development activities to avoid impacts to environmental values; and,
• Enhancement and Restoration - improve existing environmental conditions including addressing past impacts and enhancing watershed features.
A WMP for the Dawson Creek Watershed could focus on one, or more, of the above noted considerations depending on the interests of those involved in the development of the plan.
5.2.2 Content
Watershed management plans generally include the following information. In the case of the Dawson Creek Watershed, some elements of a WMP have been initiated including a preliminary description of conditions.
• Vision, goals and objectives for the watershed;
• Description of existing and potentially historic conditions;
• Identification/definition of issues and remedial options;
• Action plans to address specific issues (including objectives, time lines, priorities and roles and responsibilities);
• Description of organization structure (i.e., participants in plan development and implementation and processes for decision-making) and
• Framework for regularly monitoring and updating the plan.
5.2.3 Process
The key steps to developing a watershed management including the following.
• Assembling stakeholders
• Establishing visions and goals
• Assessing and studying the current conditions in your watershed
• Identifying the problems in your watershed
• Developing solutions and plans for your watershed
Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - 31 - January 2006
Some keys to successful watershed planning include the following:
• Inclusiveness: Developing and implementing an effective watershed management plan requires the involvement of stakeholders with an interest in the watershed. Involvement of stakeholders in plan development ensures that stakeholders will take ownership of the plan and provide the best opportunity for successful implementation.
• Leadership: While watershed planning may involve a diverse group of interests, initiating the process and keeping it going over the long term requires a committed lead agency or group that drives the planning process and ensures that initiatives are carried out.
• Management structure: Plan implementation requires a clear management structure that supports timely and effective decision-making. Management teams need to have a broad membership representative of all stakeholders and be made up of individuals that are actively involved. The management team should have the authority to make/suggest changes with respect to watershed issues and practices; have access to funding; and have the ability to implement the plan.
In the case of the Dawson Creek Watershed, some of the initial steps towards developing a WMP have been initiated including assessing conditions and bringing together some of the stakeholders. Assuming there is support for the development of a watershed management plan for the Dawson Creek Watershed, the draft LWA provides an important opportunity to bring together stakeholders to: discuss the report findings; determine if there is support for the development of a WMP; and begin development of a workplan and process to guide development of the WMP.
Development of the WMP could take place concurrent to specific actions that the stakeholders may want to focus on in order to address priority issues in the watershed.
If there is sufficient support for the development of a watershed management plan, it is recommended that a workshop be organized that focuses entirely on plan development rather than specific watershed issues. The workshop would bring together all stakeholders and focus on
Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - 32 - January 2006 confirming support for a WMP, begin identification of a vision, goals and objectives for the watershed and a process for development of the management plan. In the case of the Dawson Creek Watershed, organizations such as the Dawson Creek Watershed Society and the City of Dawson Creek, as well as adjacent land owners, could provide leadership in initiating the planning process.

6.0 CONCLUSION
This report documents the findings of the Dawson Creek Limited Watershed Assessment conducted by Hemmera on behalf of the Dawson Creek Watershed Society and the City of Dawson Creek. The purpose of the watershed assessment was to develop an understanding of the baseline watershed conditions as a first step towards action to protect and enhance the health of the watershed. Based on the limited watershed assessment, the following key issues that can be considered potential challenges to the health of the watershed were identified:
• Barrier to fish passage at Snake Pit Road (Rolla Road) Crossing;
• Water quality concerns (i.e., coliform bacteria, water temperature and dissolved oxygen), potential leachate issues near the “old” Dawson Creek Landfill;
• Low water flow potentially linked to water licenses within the watershed; and,
• Requirement for further studies to confirm fish presence/absence upstream of the Rolla Road crossing.
The findings of the LWA can be used in the short term to begin addressing priority challenges facing the watershed. This would entail taking specific recommendations, made in the LWA with respect to priority issues challenging watershed health, and developing issue specific action plans to address those issues.
The LWA can also be used initiate a dialogue among stakeholders on the need for a watershed management plan that would assist in guiding longer term efforts to protect and enhance the watershed.
How the results of the LWA will be used, will ultimately be decided by stakeholders with an interest in the Dawson Creek Watershed. In order to facilitate this decision, it is recommended that a workshop be held. Key workshop objectives could include the following:
• Discuss the overall findings of the LWA with stakeholders;
Dawson Creek Watershed Society / City of Dawson Creek Hemmera Envirochem Inc. Dawson Creek Limited Watershed Assessment File: 631-001.02 Final Report - 34 - January 2006
• Identify other information that could be included in the LWA prior to finalizing it (i.e., information that be used to better understand watershed issues, potential solutions, resources that could support watershed initiatives etc.);
• Discuss short term priorities (i.e., 2006 workplan) for acting on issues potentially challenging the health of the watershed; and,
• Gauge general support for the development of a watershed management plan.
Hemmera, as part of completing the LWA, would be pleased to present the findings of the LWA and facilitate a discussion among stakeholders on how they can build on the findings of the LWA and begin to take action to protect and enhance the health of the Dawson Creek Watershed.

APPENDIX C 1997 Peace Fisheries Field Report
PEACE FISHERIES - FIELD REPORT
SYSTEM: See NTS map sheets 93P9 and 93P16. See also the map provided of the Dawson Creek Municipal Landfill site.
DATE: July 16, 1997
PERSONNEL: Nick Baccante, Ted Euchner, Joe de Laronde, and Kerry Harvey
BACKGROUND & OBJECTIVES: As an urban stream, Dawson Creek flows through sections of agricultural, industrial and residential lands of the City of Dawson Creek. It is along this course that the stream encounters several sources that potentially could have an impact on :he creek and its fishery. Since no fisheries information had been collected for this creek prior to the July 16'~sampling date, and as a response to a variety of concerns such as the in-stream works by the City of Dawson Creek and activities at the Municipal Landfill site, sampling was undertaken to determine if fish were present or absent from this system.
MATERIALS AND METHODS: Two sample sites on Dawson Creek were selected; based in part on accessibility and the ability to safely conducted electroshocking. These sites were determined to be the Rolla road crossing (N 55" 44.728, W 120" 08.751) and the Municipal Landfill site (N 55" 45, W 120" 11 ). At the Rolla road crossing a section of stream approximately 50 m from the culvert downstream was electroshocked. Sampling was conducted for 15 minutes. At the Municipal Landfill sampling site, a section of stream also approximately 50 m was electroshocked for a duration of 15 minutes.
RESULTS AND OBSERVATIONS: Water temperature at Rolla road crossing: 17.5 "C Water temperature at Municipal Landfill: 18 "C
At the Rolla road crossing 110 fish were captured. The species composition of this catch consisted of 29 longnose suckers, 10 white suckers, 3 burbot, and 68 lake chub. At the Municipal Landfill site no fish were captured. See attached table for the data collected on this sampling date.
INTERPRETATION OR CONCLUSIONS: Additional sampling of Dawson Creek should be conducted primarily because of an impassable barrier that exists at the Rolla road crossing. As no fish were located at the second sampling site (Municipal Landfill), it is possible that fish are not passing through the physical barrier at site one. If fish are clearing this barrier it is then possible that operations at the dump are having an impact on the fishery (particularly at those sites in the immediate vaccinate of the dump). Further upstream sampling would help determine if fish do exist within this system despite physical obstacles and environmental modifications.
