"In the delta, water is boss, change is the only constant, and creation and destruction exist side by side." The Peace-Athabasca Delta in northern Alberta is a globally significant wetland that lies within one of the largest unfragmented landscapes in North America. Arguably the world's largest boreal inland delta, it is renowned for its biological productivity and is a central feature of a UNESCO World Heritage Site. Yet the delta and its indigenous cultures lie downstream of Alberta's bitumen sands, whose exploitation comprises one of the largest industrial projects in the world. Kevin Timoney provides an authoritative synthesis of the science and history of the delta, describing its ecology, unraveling its millennia-long history, and addressing its uncertain future. Scientists, students, leaders in the energy sector, government officials and policy makers, and conscientious citizens everywhere should read this lively work.

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.
