The Northern River Basins Study (NRBS) was established on September 27, 1991 by the governments of Canada, Alberta and the Northwest Territories to examine the relationship between industrial, municipal, agricultural and other development in the Peace, Athabasca and Slave river basins. The NRBS was launched in response to concerns expressed by northern residents following the late 80's decision of the Alberta Government to allocate additional forest lands for pulp and paper production. The four and one-half year study was mandated to gather and assess information relating to water and ecosystem quality, fish and fish habitat, vegetation, wildlife, hydrology/hydraulics and use of aquatic resources. This report contains key findings, conclusions and recommendations presented to the Ministers representing the governments of Canada, Alberta, and the Northwest Territories.
