Dams
The Dam Safety Office (DSO) regulates nearly 1,100 dams in Washington. Safety is our priority and we have rigorous procedures in place to protect people and property located downstream of dams.
Through plan reviews and construction inspections, we help ensure dams are properly designed and constructed. We also inspect existing dams to ensure proper operation and maintenance. In Washington, a dam owner is legally responsible to maintain, repair, or operate their dam in a safe and proper manner.
