Retrofitting Options Emerge For An Oregon Dam At Risk Of Earthquake Failure
Nearly two dozen government officials met Wednesday to discuss different retrofitting options for one of the state’s most important and imperiled water sources.
Scoggins Dam was built in the early 1970s to hold back water from the Tualatin River to form Hagg Lake. In recent years, it has been classified as a seismically at-risk dam that needs to be modified in order to reduce downstream hazards in the event of a large earthquake.
Hagg Lake is the primary water source of Washington County’s estimated 600,000 residents. Officials are looking for new ways to increase water storage for the county’s growing population.
