East Park Dam

East Park Dam is an arch dam in Colusa County, California that creates a large reservoir for water storage. The structure features massive concrete construction designed to hold water for irrigation purposes across the region.

The United States Bureau of Reclamation completed this dam in 1910 as part of the Orland Project to support agricultural water needs. The construction represented an important step in developing water resources for the region.

The control house at this structure displays pagoda-style architecture typical of early 1900s design. The curved labyrinth spillway fins are visible features that show how engineers of that era managed water flow.

The dam sits alongside a large reservoir where visitors can spend time near the water. The grounds have different areas for various activities and offer good views of the structure itself.

The reservoir has experienced extreme temperature swings that show the harsh climate conditions of the region. These extremes highlight the challenging environment that the water storage facility must endure.
