The three Upper Wabash Reservoirs are multiple-use properties that are managed in partnership between the U.S. Army Corps of Engineers and the Indiana Department of Natural Resources.

The Corps operates the flood control portion of the properties with dams under the direction of the Louisville District office in Kentucky. The Department of Natural Resources operates the recreational facilities and manages and interprets the natural and cultural resources.

• J. Edward Roush, Salamonie and Mississinewa Reservoirs were built in the 1960's to control flooding in the Wabash River.
• Constructed by the U.S. Army Corps of Engineers.
• Leased to the Indiana Department of Natural Resources for the
  secondary uses of recreation and resource management.
• Extra water is released each fall to lower lake levels, allowing the
  reservoirs to accept more runoff and snow melt in the winter and early spring.
• Water levels determined by Louisville, Kentucky Corps of Engineers
  Office to coordinate with river levels in towns downstream.

Designed, built and operated by the US Army Corps of Engineers, water levels are directed from the Louisville District Office in Kentucky. The primary purpose of the reservoirs is to furnish flood control protection for downstream towns of Andrews, Lagro, Wabash, Peru and Logansport and about 60,000 acres of agricultural land and private homes. The reservoirs release a constant supply of water year round for life in river areas downstream. Reservoir water levels are maintained at different levels or seasonal pools. For example winter pool at Salamonie covers 868 acres, the summer recreational pool is usually 2,665 acres and the flood control pool could be 9,340 acres. Pool levels can vary significantly from scheduled levels if flood storage is necessary.
