1.0 HABITAT MEASUREMENTS AND DETERMINATION OF HABITATSUITABILITY INDEX VALUES FOR AFFECTED WATERCOURSESAND WATERBODIES
Using information gathered during the preparation of the Jackpine Mine Expansion and Pierre River Mine
Environmental Impact Assessment and supplemental baseline studies conducted in the summer of 2008, data
were compiled for the variables needed to calculate Habitat Suitability Index (HSI) values and Habitat Units.
This appendix presents the results of HSI determinations for fish species in watercourse reaches and
waterbodies for which habitat data were available. These HSI determinations are based on application of the
HSI models described by Golder (2008). Some HSI values were based on the HSI models developed by the
United States Fish and Wildlife Service (USFWS) and the original models should be referenced for details
(Edwards 1983; Hubert et al. 1985; Inskip 1982; Krieger et al. 1983; McMahon et al. 1984; Twomey et al. 1984).
When no habitat data were available for a particular watercourse reach, a conservative assumption was made
that the HSI for each species was equal to the HSI for those species in the nearest downstream reach.
Assumptions made in regards to HSI values used for species when no habitat data were available can found in
Table 5 of the main draft No Net Loss Plan document.
Habitat data and HSI determinations for watercourses and waterbodies affected by the Jackpine Mine Expansion
can be found in Tables B1 through B69. Habitat data and HSI determinations for watercourses and waterbodies
affected by the Pierre River Mine can be found in Tables B70 through B273. Habitat data and HSI
determinations for watercourses affected by the Project in the Redclay Creek watershed can be found in Tables
B274 through B309. Habitat data and HSI determinations for one waterbody potentially affected by the Project
in the McClelland Lake Drainage Area can be found in Tables B310 through B311.

(a)Throughout this appendix, substrate categories are as follows: bedrock, boulder (> 256 mm), cobble (> 64 mm to 256 mm, rounded),rubble (> 64 mm to 256 mm, angular), gravel (> 2 mm to 64 mm), sand (> 0.06 mm to 2.0 mm) and clay/silt (≤ 0.06 mm), which includes detritus/organic matter. The distinction between cobble and rubble is that cobble material has a smooth rounded shape, while rubble ismaterial in the same size range, but with sharp angular corners.
(b)Throughout this appendix, late winter DO concentration criteria are based on the assumptions that if measured late winter DO is greaterthan the indicated concentration, DO is not limiting at any time of year, and if measured late winter DO is less than the indicatedconcentration, DO may be limiting in winter but not during the open-water period. In addition, since DO is not measured in all areaswithin a watercourse or waterbody, there may exist some local areas where late winter DO is greater than the measured concentrations.Late winter dissolved oxygen for Muskeg River Reach 6b is the 10th percentile of measured late winter values from historic monitoringresults for Muskeg River reaches upstream of Muskeg Creek (see Appendix D).
