Summary

Beaver Lake was constructed in 1966 on the White River in the northwest corner of Arkansas for flood control, hydroelectric power, public water supply, and recreation. The surface area of Beaver Lake is about 27,900 acres and approximately 449 miles of shoreline are at the conservation pool level (1,120 feet above the North American Vertical Datum of 1988). Sedimentation in reservoirs can result in reduced water storage capacity and a reduction in usable aquatic habitat. Therefore, accurate and up-to-date estimates of reservoir water capacity are important for managing pool levels, power generation, water supply, recreation, and downstream aquatic habitat. Many of the lakes operated by the U.S. Army Corps of Engineers are periodically [...]

Purpose

Sedimentation over time can result in reduced reservoir capacity. The U.S. Army Corps of Engineers, are tasked with ensuring adequate reservoir capacity for activities such as: consistent pool levels, power generation, water supply, recreation, and downstream aquatic habitat. Continued bathymetric surveys provide an accurate estimate of reservoir capacity, as well as sedimentation rates. The U.S. Army Corps of Engineers requested a bathymetric survey of Beaver Lake to provide a surface area and capacity table and bathymetric map.
