Water quality samples were collected from the Little River system in Pine Creek Lake, Oklahoma, and Gillham Lake, Arkansas, and their associated tailwaters during the winter (reservoirs unstratified) and summer (reservoirs stratified) of 1980. Downstream water quality was not affected by reservoir water releases while the reservoirs were unstratified. When the reservoirs were stratified water quality in the tailwaters was dependent on the release depth of the water. The practice of flushing out a tailwater following an extended low flow period should be examined on a site by site basis. Anoxic water released from a reservoir may contain high amounts of certain chemicals that may be detrimental to downstream aquatic life.
