having a nameplate capacity of 44,099 kW, for a total of 132.297 MW. The hydroelectric power plant provides enough electricity to supply 68,000 homes. Power generated is sold through the Western Area Power Administration. Reservoir See main article: Lewis and Clark Lake Gavins Point Dam creates Lewis and Clark Lake, a popular regional tourist destination for water-based recreational opportunities including boating and fishing, along with camping, hiking, and hunting opportunities managed by the State of South Dakota, State of Nebraska, and the U.S. Army Corps of Engineers. The lake is significantly impacted by sedimentation and siltation issues, diminishing the overall water surface area, water storage capacity, and recreational opportunities. Sediment carried by the Missouri River and Niobrara River is slowed and trapped within the reservoir due to the dam impounding and thus stopping the natural river flow. Studies show approximately 5.1 million tons of sediment are deposited in the lake each year, which contributes to the lake's increasing size of delta area on the western portions of the lake. Approximately 60% of the sediment comes from the Nebraska Sandhills via the Niobrara River. As of 2016, approximately 30% of the lake's overall surface area has diminished due to sedimentation deposits, and some figures project by 2045 approximately 50% of the lake will be diminished due to sedimentation deposits. Presently, there is no plan or solution to remove or slow the progression of the siltation within the lake.
