760 Flood stage, capacity of dam is reached. Spillway utilized. Dam must release flow. Major flooding likely downstream all the way to Rochester area. Co-ordination necessary among affected agencies for possible evacuations.
720 Action-alert stage. Pool significantly full. Increase monitoring.
600 Conservation pool, june 15 to november 1, maintained as close to this level as possible.
584 Pool elevation. Typical low level-uncontrolled.
575 River bed elevation.
