Prineville Reservoir State Park

Park History

As part of the Crooked River Federal Reclamation Project, the Department of the Interior authorized the construction of Bowman Dam between 1958 and 1961.  The project's purpose was to furnish water for irrigation, flood control and fish and wildlife management.   Through the Crook County Court, and a lease from the U.S. Bureau of Reclamation, the land for the park was obtained in 1961.  A lease agreement between the Bureau of Reclamation and the Oregon Parks and Recreation Department allows the State to manage and maintain the natural resources and recreational uses on the reservoir.

Where can I swim?

The lakes and rivers found within Oregon State Parks are open to unsupervised swimming. You are responsible for your own safety. Before you enter the water, you should judge your swimming skills against possible strong currents, cold water, underwater objects and steep drop-offs. Remember, that many of our natural bodies of water and man-made reservoirs are filled by snow runoff and remain cold year round. Please bring and wear a personal flotation device and swim with a buddy.
