Republican River Flood of May 30, 1935

 This website is dedicated to preserving the history of the Republican River Flood of 1935.


A series of dams and reservoirs were constructed along the Republican River Basin to control the river flow to prevent future floods, for agriculture irrigation, and recreational uses.  The project to create most of these dams was the Pick Sloan Missouri River Basin Program Project. The divisions of this project that encompass the Republican River are the Armel Unit (Bonny Dam/Reservoir), Frenchman-Cambridge Division (Enders Dam/Reservoir, Harry Strunk Reservoir/Medicine Creek Dam, Hugh Butler Reservoir/Red Willow Dam, Swanson Reservoir/Trenton Dam), Bostwick (Harlan County Dam/Lake), and Almena Unit (Norton Dam/Keith Sebelius Reservoir).
