Abstract
Repetitive reservoir storage capacity surveys are often thought to provide one of the most accurate methods to assess basin sediment yield. The Omaha District conducts a large scale sediment data collection and analysis program for six Missouri River mainstem and twenty-two tributary reservoirs. An analysis was conducted to compare the sediment yield, reservoir capacity, depletion trends, and comparison between projects for effects on project sustainability. Trend analysis is complicated by temporal variation in conservation practices that affect sediment yield, new reservoir survey techniques, and revised capacity computation methods. Results provide insight on the variation in basin sediment yield, reservoir depletion rates, variation due to a change in survey method, and impacts on long term reservoir sustainability.
