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.

Did you know that rainfall in the Mosier watershed ranges from 60″ at the headwaters near Gibson Prairie to a mere 17″ on Sevenmile Hill?

Learn more on the Mosier Watershed Council’s website. Council meetings are held on the last Wednesday of January, April, and October. Recent projects have included addressing co-mingling wells, and drilling new deeper wells to help manage the area’s finite water resources.
