Summary: The primary objective of this project is to enhance Providence Creek to increase arctic grayling (Thymallus arcticus) spawning habitat. This will be done by removing beaver dams which have been shown to decrease usable spawning habitat, and to create new spawning habitat with gravel and boulders. Another objective of the project is to monitor the arctic grayling population to determine if the ...

Summary: The objectives of this research project are: to study the freshwater ecology, hydrology, and hydraulics of small lakes and streams in the Lac de Gras basin before habitat modification; to monitor the changes in ecosystem productive capacity resulting from habitat modifications designed to increase habitat connectivity and fish passage; and to assess the effectiveness of such habitat modifications ...

Principal Investigator: Scott, Janet L
Licensed Year(s): 2008
Summary: This licence was issued for the application no. 802. The objective of the 2008 fieldwork is to monitor vegetation, invertebrates, and fish populations associated with lakeshore and stream habitat restoration and enhancement. Data will be used to evaluate the continuing success and effectiveness of restored or enhanced stream and lakeshore habitats against control sites, through time. Field ...

Summary: The purpose of this study is to collect biological information from both the control sites and the treatment sites within Matthews Lake and the surrounding area. The objective is to monitor these sites and collect enough information to evaluate the effectiveness of the 2004 habitat enhancement and construction activities. Field crews will fly to Matthews Lake, landing either on the runway or th...

Summary: The research team will be based in Yellowknife, and transported to Prelude Lake by truck. Transport on the lake will be by 20' Alaskan boat equipped with a 55 hp motor (supplied by the North Slave Metis Alliance). Baseline information will be collected on the composition of a number of target species: Lake Trout, White Fish, Cisco, Burbot, Northern Pike and forage species. Both 30 m beach seine...

Summary: This program is a detailed assessment of the created/enhanced habitat at Frank Channel, based on fish use and function in comparison with habitat design targets. Habitat monitoring will require seasonal assessments within the open water period at times associated with the targeted fish's life stages (Northern Pike). During early spring, mid summer and late summer, Frank Channel habitat will be m...

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...
