While reservoirs are constructed to regulate stream flows for several beneficial purposes including flood control, water supply, hydroelectric power, irrigation and low flow augmentation and to enhance water based recreation, they create problems of water quality that offer a new dimension to the task of efficient operation. Among other potential deleterious effects, thermal stratification in reservoirs inhibits mixing and causes a deterioration of dissolved oxygen levels in lower layers. Several investigators have examined the thermal properties of reservoirs and resultant effects upon dissolved oxygen and have suggested alternative schemes for alleviating detrimental effects (1,2,3,4,5). The objective of this paper is to outline a methodology for evaluating some of these alternatives in a river‐reservoir system where downstream water quality control is one of several purposes to be served by the reservoir.
