Crane Prairie is a federal-owned reservoir located in Deschutes, Oregon, with a primary purpose of irrigation. The dam, completed in 1939, stands at a height of 36 feet and has a storage capacity of 68,800 acre-feet. The reservoir covers an area of 4940 acres and is fed by the Deschutes River, with a maximum discharge capacity of 800 cubic feet per second.

The dam at Crane Prairie is classified as an earth dam with an arch core type and rock foundation, standing at a hydraulic height of 27 feet. In 1991, both hydraulic and structural modifications were made to the dam. The reservoir has a spillway width of 80 feet and is considered to have a high hazard potential. While the condition assessment is not available, the risk assessment for the dam is moderate.

Even though Crane Prairie primarily serves irrigation purposes, it is also a critical water resource for the region and plays a crucial role in managing water supply and flood control on the Deschutes River. The reservoir's location and design make it a vital asset for water resource and climate enthusiasts interested in understanding the management and maintenance of dams in Oregon.
