The Oregon Watershed Enhancement Board (OWEB) is a state agency led by a 17-member policy oversight board. The Board fosters the collaboration of citizens, agencies, and local interests.

OWEB programs support Oregon's efforts to restore salmon runs, improve water quality, and strengthen ecosystems that are critical to healthy watersheds and sustainable communities. OWEB administers a grant program funded from the Oregon Lottery, as a result of a citizen initiative in 1998, federal funds and salmon license plate dollars. The grant program supports voluntary efforts by Oregonians seeking to create and maintain healthy watersheds.
