13. ABSTRACT (Maximum 200 words)
In recent years, drought conditions in the Missouri River basin have required more accurate control of releases
at Gavins Point Dam, the furthermost downstream flow control structure on the river, to meet competing water
needs for irrigation and recreation upstream and for navigation and municipal and industrial water supply
downstream. In winter, ice accumulations can seriously affect flow distribution along the river. This paper
summarizes a study of such ice effects. It proposes methods to determine minimum flow releases at Gavins Point
Dam to meet downstream water supply without unduly depleting upstream reservoirs.
