Summary: This study involves fish sampling to determine relative abundance and levels of mercury and other metals in fish tissue in Giauque Lake, Thistlethwaite Lake and Control Lake A, as well as benthic invertebrate sampling and water quality sampling in the three lakes to complement the fish sampling. 3 sites in Giauque, 3 in Thistlethwaite and one in Control Lake A will be recorded. Captured fish will ...

Summary: The researchers will measure water quality, aquatic ecology and the status of fish populations in ponds and lakes along the proposed discharge route of mine water from the Colomac Mine (North Pond, L-Shaped Lake, Paddle Lake, Lake 315, and Lower Lake) and compare those data with data collected from reference lakes (Steeves Lake, Baton Lake, and Spanner Lake). Work will include taking three samples...

Summary: The main objective of this study is to characterize environmental conditions and supplement existing environmental information for possible use in long-term (i.e., multi-year) Environmental Effects Monitoring (EEM) programs as required of the Giant and C...

Summary: In 1999, the Northwest Territories Power Corporation was awarded a 25 year water licence to operate its three hydroelectric plants on the Snare River. Conditions of this water licence included that two studies be done by the Corporation. The first study is an assessment addressing the removal of minimum flow requirements on two of the dams. This study will include a current assessment of fish a...

Summary: Recently BHP Diamonds Canada has "dewatered" a number of lakes and created a diversion channel to re-route water around two open pit mines. The purpose of this study is to compare the effectiveness of the diversion canal as habitat before and after it is enhanced with fish habitat structures and also in relation to natural streams in the area. In early spring Arctic grayling will be captured in we...

Licensed Year(s): 1994
Summary: In project area streams, fish presence/absence and/or densities will be obtained by electrofishing representative habitat. Benthic invertebrates ans periphyton (stream algae) will be sampled at stream sites to determine seasonal changes in composition, distribution and abundance. Lake fisheries population studies will involve fish trapping. Lake limnology, plankton and benthic invertebrates wil...
