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 ...

Summary: The objective is to study ice processes on the Hay River in order to continue the ongoing development of computer models to predict them. Also, the team has developed some flood warning tools for the community and we are interested in testing and enhancing them. In order to develop realistic models, it is important that the researchers have the opportunity to observe river breakup so as to have...

Summary: The objectives of this project are: (1) to develop improved understanding of, and ability to predict, snowcover formation and melt, as well as stream discharge in northern regions, and (2) to develop an improved understanding of, and ability to predict, water levels in the lakes and channels of the Mackenzie Delta. These will allow a better understanding of the impact of climate change and/or natu...

Summary: The Arctic Ocean receives much higher river inflows than other ocean basins and this has major implications for sea-ice formation, for nutrient supply to the base of aquatic marine foodwebs, and for optical properties of ice-free areas and ice-pack margins via fluxes of dissolved organic matter and riverine particles. The Beaufort Shelf is strongly influenced by Mackenzie River outflows. However, ...

Summary: It is known that extreme flood levels within the Mackenzie River Basin are caused by ice jamming events. Analysis of open water versus ice influenced water levels at several sites within the Mackenzie River Basin will provide further quantification of th...

Summary: The research team proposes to collect information about fish habitat features and use on watercourse crossings located within the tentative pipeline corridor in the Deh Cho Region. All aquatic studies will be conducted by three or four-person crews. Each crew will include a local researcher or community representative. Depending upon accessibility, sites will be accessed by helicopter and an i...

Summary: The research team proposes to collect information about fish habitat features and use on watercourse crossings located within the tentative pipeline corridor in the Inuvialuit Settlement Area. The research team will survey 14 permanent watercourses, as well as several intermittent or seasonal watercourses and approximately 20 lakes located along the study corridor to determine aquatic characteri...

Summary: The research team proposes to collect information about fish habitat features and use on watercourse crossings located within the tentative pipeline corridor in the Gwich'in Settlement Area. All aquatic studies will be conducted by three or four-person crews. Each crew will include a local researcher or Renewable Resource Council (RRC) representative. Depending upon accessibility, sites will b...

Summary: The research team proposes to collect information about fish habitat features and use on watercourse crossings located within the tentative pipeline corridor in the Sahtu Settlement Area. Surveys of fish and fish habitat will be made at 62 permanently flowing watercourses, as well as 15 intermittent streams. These studies will include hydrology and water quality work as well. All of the aquatic ...

Summary: The research team will be based in Ft. Resolution. Transportation includes aircraft from Toronto to Edmonton to Hay River. Transportation in the field will be by truck and boat. The research team will operate from a base camp previously established on Steamboat Channel (a camp we originally established in 1977 when this work originally started). Water level recorders will be established at six sit...
