GLOSSARY AND KEY OF TERMINOLOGY, ABBREVIATIONS, AND SYMBOLS USED IN THE FISH-BEARING ATLAS FOR PIPELINE AND POWER LINES

Channel Morphology Pattern The path of a channel in relation to a straight line. A qualitative method of assessing sinuosity. Confinement The ability of the channel to migrate laterally on a valley flat between surrounding slopes. Bank Shape The shape or form of the identified channel bank described when the observer is facing downstream. Habitat Unit Description of the morphological unit observed within the section investigated. Gradient The slope or rate of vertical drop per unit of length, of the channel bed. Main Stem The name of and distance to the nearest watercourse known to be fish-bearing (FB) habitat, as measured from the approximate proposed crossing location. Wetted Width The width of the water surface at the time of survey; measured at right angles to the direction of flow. Channel Width The distance between the ordinary high water mark of both right and left banks. Bank Height The height measured from the channel bottom at the watercourse’s deepest point at the transect to the bank’s break in slope at its top, such that the grade beyond the break is flatter than 1:3 (rise:run) at any point for a minimum of 15 m measured perpendicularly to the bank. Where banks are not well defined (e.g., in the case of wetlands, gently sloping inside bend or beaver ponds), the top of the bank is equivalent to the ordinary high water mark. Pool Depth Maximum pool depth as measured from the current surface level to the deepest point in the unit. Water Quality/Quality Water Temperature The ambient stream water temperature. Conductivity The ability of a solution to carry electric current. pH A measure of hydrogen ion concentration on a scale of 0 (highly acidic) to 14 (highly basic) with a pH of 7 as neutral. Dissolved Oxygen The concentration of oxygen dissolved in water, measured in milligrams per liter. Discharge The volume of water transported past an arbitrary point in a set amount of time, expressed as cubic meters per second. Flow Regime The pattern of channel flow in time and space. Turbidity A visual assessment of the concentration of suspended sediments and particulate matter in the water. Substrate Described as a percent composition over the LSA. Organics Size: N/A – leaf litter, sticks Fines < 2 mm Small Gravel 2-16 mm Large Gravel 17-64 mm Cobble 65-256 mm Boulder > 256 mm Bedrock > 400 mm Cover Dominant The dominant type of structure that provides cover for hiding, resting or feeding fishes. Subdominant The subdominant type of structure that provides cover for hiding, resting or feeding fishes. Riparian Described as the vegetation on land adjacent to the top of the bank of a watercourse. Type Grasses (G); Shrubs (S); Coniferous (C); Deciduous (D); Mixed Conifers and Deciduous (M); None (N); Wetland (W). Maturity State of maturity of riparian vegetation. Initial Stage is <5% tree cover, Shrub is <10% tree cover, Pole Sapling is <15- 20 years old, Young Forest is forest canopy is differentiated into distinct layers, and stand age is 30-80 years, Mature Forest with a well-developed understory, Not Applicable is riparian veg is absent and area dominated by grassland or wetland. Crown Closure The amount of canopy closure provided by riparian vegetation which projects over the stream channel, directly above the thalweg, and is > 1 m above the water surface. Binned into ranges for estimation purposes: 0%; 1-20%; 21-40%; 41-70%; 71-90%; > 90%. Fish Presence and Life History Stage YOY Young of the year; fishes less than 1 year old. Juv Juvenile; fishes greater than 1, but not able to spawn. Adult Fishes at spawning age. Unknown Age was not discernable externally. Species Acronyms are provided on Page xii of the Supplemental Fisheries (British Columbia) Technical Discipline Report. Fish Habitat Potential Description of the assessed habitat potential per species and life stage considered. N None L Low M Moderate

M-H Moderate - High H High Sampling Effort EF Backpack Electrofishing. Effort measured in seconds (s). FLEF Float Electrofishing. Effort measured in seconds (s). MT Minnow trap. Effort measured in hours (h) of trap deployment. All traps were Gee Type minnow traps (baited). Provincial Window of Least Risk Species and region specific windows established to protect sensitive life history stages of species of management concern, outlined in Section 4.1.5 of Technical Report 5C-7 in Volume 5C, Fisheries (British Columbia) Technical Report (Triton December 2013; Filing ID A3S2C1). Least Risk Biological Window Proposed QAES-recommended preferred period of time for construction, with consideration for the associated Provincial Window of Least Risk and habitat potential identified within each Fish and Fish Habitat LSA. Construction Timing Expected timing of construction, as defined by engineering. Stream Classification BC Navigability The ability of the watercourse to be traversed by any type of floating vessel for the purpose of transportation, recreation or commerce, as determined by the field crew. Navigability status definitions and the screening criteria used to make field based determinations are outlined in Section 3.3 of the Fisheries (British Columbia) Technical Discipline Report. Barriers to Fish Movement Describes if there are objects in the channel that will limit fish migration (i.e., a perched culvert and subsurface flow). Active Beaver Dams Describes if active beaver dams were observed during the field investigations. Historical Fish Presence Lists fish presence previously documented for that watercourse over its entirety. Sensitivity A qualitative measure of the sensitivity of a watercourse to disturbance, based on the type and diversity of fish species present, their respective life-history stages and the habitat potential across all seasons. Definitions related to Low and High Fish Habitat Sensitivity ratings are provided in Table 3-6 of the Fisheries (British Columbia) Technical Discipline Report. Low Fish Habitat Sensitivity

Frequent pools offer moderate overwintering potential; pockets of gravels provide suitable spawning habitat although limited by sections of large cobble and boulder substrate. No land access was permitted; watercourse classification, sampling effort and habitat sensitivity is based on data collected during

helicopter overflights and during fish salvages for KMC Maintenance Works.

Historical Fish Presence: RB

Sampling Effort Method Time Distance Date Comments: Marathon Creek is a perennial watercourse which provides moderate potential for RB and BT attributed to watercourse size, perennial flow and suitable substrate for spawning. Historical presence of RB, although Marathon Creek also has potential for BT; habitat conditions are similar to Baer Creek and Terry Fox Creek. No land access was permitted; watercourse classification and habitat sensitivity is based on data collected from helicopter overflights and by traversing the existing TMPL ROW during KMC Maintenance Works; existing ClearSpan Bridge is in good

condition.

Sampling Effort Comments: Method Time Distance Date Small seasonal watercourse with low fish habitat potential at the PPC, attributed to small channel size, steep gradient EF 172 s 300 m 170514 (25%), low discharge, shallow depths, and sections of poor connectivity downstream from the PPC; three juvenile RB EF 300 s 400 m 030714 were captured below steep gradient section approximately 360 m downstream from the PPC at the confluence with the Fraser River; functional fish habitat for approximately 20 m upstream from confluence; gradient and lack of flow at and near PPC preclude fish presence, and no fish were captured here over two seasons of sampling; maintain water

quality downstream during construction; least risk biological window proposed includes potential for BT.

Historical Fish Presence: BT, LSU, RB, CCG, MW, PW, KO Sampling Effort Method Time Distance Date Comments: EF 263 s 100 m 160812 The Canoe River is a large perennial channel with moderate habitat potential for salmonids within the PPC; juvenile BT were captured within the ZOI at velocity breaks along channel edges; cover includes undercut banks, OHV and LWD; a sidechannel area with suitable rearing habitat is located 350 m downstream; however overall rearing and wintering habitats are limited by extensive fast riffles and a lack of pool/run formations; the substrate is composed of a mixture of course material; high percentages of large cobble and boulder limit overall spawning potential; the Canoe

River provides a migratory route for Kinbasket Lake KO; the river is subject to high flows during the spring/summer; armouring will likely be required for trenched options.

Sampling Effort Comments: Method Time Distance Date Small confined watercourse with moderate habitat potential for salmonids; below Hwy 5, the channel provides good EF 642 s 200 m 310712 spawning and nursery habitat attributed to good cover and instream complexity; abundant juvenile and YOY RB were captured or observed. Upstream from Hwy 5 the gradient increases (12%) and habitat potential is limited by channel size, perched culverts and occasional bed drops; spawning gravels occur below Hwy 5, but above the Hwy, spawning habitat is limited by an increase in gradient and substrate size; wintering potential is low given the small channel size and low discharge; 1 adult RB was captured near the PPC and fish salvage is recommended; maintenance of water

quality/quantity is important given abundance of juvenile salmonids observed near the confluence with Camp Creek.

Sampling Effort Comments: Method Time Distance Date The Albreda River at the PPC provides high rearing habitat value for salmonids, which is attributed to high instream EF 14 s 5 m 030812 complexity and suitable offchannel rearing areas. Ample cover is provided by overhanging vegetation, woody debris, MT 37 hrs 210806 deep pools, and undercut banks; abundant juvenile CO captured and observed within the ZOI in 2006 and 2012; spawning potential limited by high percentage of fines, although there are sparse pockets of gravel; deep overwintering pools located upstream and downstream; headwaters of Albreda River are lakefed; likely manageable

for an isolation during low flow periods; avoid disruption of offchannel habitat along left and right banks and restore

riparian areas.

Historical Fish Presence: BT

Comments: Sampling Effort Robina Creek has overall moderate habitat potential for BT; no fish were captured or observed at or adjacent to the Method Time Distance Date PPC which is attributed to gradient (2434%); juvenile BT were captured below Hwy 5 in 2006 and 2012 at EF 694 s 300 m 180812 approximately 250 m downstream from the existing TMPL ROW where the gradient lowers to 13%; abundant cover MT 80 hrs 200606 (boulders, undercut banks and overhanging vegetation) provides moderate rearing habitat; spawning potential is low given predominance of cobbles/boulders; moderate wintering habitat is attributed to moderate discharge and occasional pools; maintenance of downstream water quality and quantity is important as there is potential for BT within the ZOI; isolation with water quality monitoring should proceed when flow is most manageable.

Sampling Effort Comments: Method Time Distance Date Moderate to high rearing potential for CO in ponded area downstream from the existing TMPL ROW attributed to pool MT 192 hrs 190812 habitat and instream vegetation; upstream from the existing TMPL ROW there is a lowlying seepage area with EF 50 s 25 m 190812 minimal habitat value; a 300 mm culvert across the existing TMPL ROW drains from the seepage area to the ponded MT 76 hrs 200606 area downstream; juvenile CO and abundant amphibians were captured or observed in the downstream ponded area in 2012; CO and BT were captured in 2006; ponded area is connected to the Albreda River by culvert under Hwy 5;

pool habitat in ponded area may persist year round, providing moderate wintering potential; substrates are unsuitable for spawning; pipeline and vehicle crossings should preserve riparian habitat and minimize downstream siltation.

Sampling Effort Method Time Distance Date Comments: EF 106 s 150 m 190812 Juvenile CO were captured in watercourse approximately 165 m downstream (at confluence with BC70); habitat potential for juvenile CO near PPC is nil given an impassable culvert barrier, shallow depths, low discharge, sub surface sections and gradient (1822.5%); rearing quality improves downstream from culvert barrier where gradient is flatter but habitat is still limited by low discharge and a lack of pool formation; a high percentage of fines precludes all

spawning potential; the channel is likely frozen to the bottom during the winter; maintenance of downstream water

quality and quantity is important given potential for juvenile CO below barriers downstream.

Sampling Effort Comments: Method Time Distance Date Perennial watercourse with low potential for fish at the PPC; multiple barriers to fish passage exist downstream, EF 316 s 300 m 190812 including a 70 m long wooden causeway that acts as a velocity barrier and 2 perched culverts at Hwy 5; wintering potential near the existing TMPL ROW is also limited by a lack of pool formation although there is moderate potential for spawning and rearing. At approximately 350 m downstream (below Hwy 5) channel is fishbearing and juvenile CO

were captured; maintain downstream water quality/quantity during construction.
