Author(s) Dam Safety Section
Description The Washington Department of Ecology is conducting an inspection program of dams built without permits which may pose a risk to people and property.
At least 96 irrigation and industrial ponds, sewage lagoons and dairy waste lagoons were identified statewide in aerial photos that appeared to be "high hazard" reservoirs, holding at least 10 acre-feet of water or liquid and located upstream from at least three homes.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
