Construction of the Bennett Dam in British Columbia altered natural fluctuations of downstream flows in the Peace River in Alberta, with major implications for the ecosystem of the Peace-Athabasca Delta. In later years, downstream weirs were constructed to restore the water level regime in the Delta. This report presents the results of a modelling exercise undertaken in an attempt to assess the effect of the weirs and the dam on the Delta water levels during 1985-90, at which time Lake Athabasca water levels were low and it was not clear whether the weirs were functioning properly or if the low water levels were caused by low flows coming from the upper Peace and Athabasca river basins. The methodology uses a one-dimensional hydrodynamic model, suitably modified and calibrated. The appendices include numerous plots of water levels indicating the effects of the weirs and dam on natural conditions.

In September 1974, Canada, Alberta and Saskatchewan agreed to construct remedial works in the Peace-Athabasca Delta to partially restore water levels which had been adversely affected by construction of the W.A.C. Bennett Dam in British Columbia. This final report provides an assessment of the remedial works undertaken and presents the results of ancillary studies conducted by the Committee on the growth of Creed Creek, a possible structure on the Quatre Fourches, fish passage at the weirs and modifications to the boat tramway. Recommendations for long-term hydrological and biological monitoring are included.

The NTBS was designed to address the ecological concerns about pulp mill expansion, and to increase scientific knowledge about environmental conditions [ecology, ecosystem sustainability, water pollution and control, habitat, effect on fish and fishing, etc.] in the major river systems of the north. The study's objectives were to gather and interpret sound scientific information about the basins, develop appropriate recommendations for basin management, and communicate effectively with the public. The government response report confirms the governments' commitment to ecosystem sustainability and to pollution control in northern rivers. First Nations and Metis aboriginal [native] peoples contributed significantly to the NRBS.
