The Mosier watershed area encompasses all land drained by Mosier, Rock, and Rowena Creeks and their tributaries, along with associated lands which drain directly to the Columbia River.
Wasco County’s Watershed Councils are voluntary, local organizations authorized by the State of Oregon and recognized by the County Board of Commissioners. The Councils were established to help address natural resource and watershed conservation and enhancement in Wasco County.
The Mosier Watershed Council works to foster an understanding of watershed resources and to then work cooperatively to improve watershed health. Since the City of Mosier’s water comes from wells, watershed health is vital to the well-being of humans, animals, agriculture, and vegetation alike.
