Bowman Dam was completed by the US Bureau of Reclamation (BoR) in 1961, damming the Crooked River and creating Prineville reservoir. It was built to protect development downstream from flooding, including the City of Prineville, and to provide water for Ochoco Irrigation District (OID) who operates the dam. While these are worthy goals, Bowman Dam has also caused significant environmental damage. OID, Prineville, and Crook County would now like to add a small hydroelectric facility to the base of Bowman Dam and are asking for a waiver to the State of Oregon requirement that fish passage be provided at dams undergoing significant changes. This is a complex issue, below are my thoughts. The waiver application, supporting documents, and analysis by the Oregon Department of Fish & Wildlife can be found here. Public comment on the waiver application is being accepted until June 22nd.Read More »





Three federal agencies (Bureau of Reclamation, National Marine Fisheries Service, and US Fish & Wildlife) manage water releases out of Prineville Reservoir into the Crooked River. As of last week, they believe flows for fish and wildlife can be maintained through the winter. Prineville Reservoir has a capacity of 148,640 acre feet of water, approximately half of which is guaranteed for irrigation. Water in excess of that at the beginning of irrigation season is “fish water” to be released for the “maximum biological benefit” for fish and wildlife. Irrigation season ends in a month and Prineville Reservoir is still 66% full, leaving plenty of fish water to release during the winter. Keep reading for more details.
