FERC Relicensing Status
The State of Oregon removed Sodom and Shearer Dams in 2011. The state park now in place is using the associated mill as an interpretive center. OPRD is designing a closed system to allow water use for mill demonstration while using screened inflow which resolves the potential for fish entrainment. The State will continue to monitor river conditions following dam removal for 10 years.
