Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references (p. 23). "Simulation modelling was used to assess effectiveness of water regime control measures on the Peace-Athabasca delta. Two weirs were constructed in 1975 on the outlet channels of Lake Athabasca in order to offset undesirable changes in the flow regime of the Peace River that were caused by the Bennett Dam in British Columbia. A computer model developed during the Peace-Athabasca Delta Project study was used to translate effects of this regulated weir regime and two others (natural, Bennett Dam) into wildlife numbers and habitat changes, so that productivity comparisons could be made between regimes"--Executive summary, p. iv.
