Limited regulation of Lake Erie would involve increasing its outflows during periods of high water supplies to the upper Great Lakes from which Lake Erie receives over 80 percent of its water. This would require regulatory works which would increase the outflow from Lake Erie in the Buffalo-Fort Erie area. The works would be opened during periods of high supplies and thus lower the levels of Lake Erie. Out of a number of possible Niagara regulatory works plans, three were selected for detailed analysis: (1) the modification of the existing Black Rock Navigation Lock to provide an outflow increase of about 110 cubic metres per second (4,000 cubic feet per second); (2) a diversion channel across Squaw Island equipped with a control structure to provide an outflow increase of about 280 cms (10,000 cfs); and, (3) a channel enlargement in the Niagara River together with a compensatory structure in the vicinity of the Peace Bridge to provide an outflow increase of about 710 cms (25,000 cfs). By comparison, the long-term average Niagara River flow is about 5660 cms (200,000 cfs). Thus, these increases would represent 2 to 12 percent of the average river flow.
