Low flow criteria for impoundments and diversions were formulated through a multidisplinary task force and are being used by the State of Pennsylvania. Watershed size, low flow yield of the stream, reservoir capacity, and water quality were considered in the formulation of the criteria. The criteria were implemented using a simple chart which provides a transition from an impoundment to a diversion. The techniques used to arrive at the chart and formula are applicable to reservoirs and diversions elsewhere.
