Description:

Abstract:

The State of Washington has 1195 “existing” dams. These dams are defined as structures that can impound 10 acre-feet or more of watery material at the dam crest elevation. Dams that had been removed or breached are not included. As of 2017 there are 1195 “existing” dams all of which are being operated in the 39 Washington State counties.

Purpose: Show locations of dams in Washington State

Supplemental_Information:

In Washington State, dam safety concerns were part of the normal water-rights duties in the state departments of Conservation and Development and Water Resources. In 1970, dam safety regulations were transferred to newly-created Department of Ecology. In the early 1980s, a separate Dam Safety Section was formed to concentrate on dam issues, primarily in response to the National Dam Safety Act in 1977. In 1990, Ecology's Dam Safety Office was reorganized and initiated its first long-range planning for improving dam security in Washington. The result was the creation of a new law in 1992 (Chapter 173-175 WAC, Dam Safety) and the development of Dam Safety Guidelines, a multi-volume compendium of design standards, requirements and technical guidance.
