Overview of Bowman Dam and the Crooked River System
What is Bowman Dam?
Bowman Dam is a crucial component of the Central Oregon Project, constructed in the mid-20th century to regulate water flow, support irrigation, and provide hydroelectric power. Built on the Crooked River, the dam stands as a testament to engineering ingenuity, creating Bowman Lake and controlling downstream water flow to meet regional needs.
The Role of the Crooked River
The Crooked River is a prominent waterway that runs approximately 126 miles through Oregon's high desert and forested landscapes. Its headwaters originate in the Cascade Range, gathering snowmelt and rainfall, then coursing through rugged terrain before merging with other water systems. The section below Bowman Dam is particularly notable for its rapid changes in flow, diverse ecosystems, and recreational appeal.
