EightMile Lake Dam Response Frequently Asked Questions What is the problem with the dam? There is no imminent threat. However, a 2017 wildfire decimated vegetation around the deteriorating dam on Eightmile Lake, leaving the area vulnerable to erosion, flash flooding and possible dam failure that could impact downstream homes and property. The dam in the Alpine Wilderness Area, serves as a water source for the Icicle-Peshastin Irrigation Districts (IPID). Chelan County Emergency Management Department is working with the IPID, the U.S. Forest Service, National Weather Service, Washington Department of Ecology, Washington Department of Emergency Management and the community to assure all downstream residents are safe during this period of repair at the dam. What’s the most current info on dam conditions? Dam repair efforts are under way. Phase 1 of the interim action plan was substantially completed May 17. That phase reshapes and armors the crest of the dam to act as a spillway, which greatly increases the dam's ability to safely pass water. The next phase will be to install a siphon to allow access to the dam’s outlet pipe which is clogged and not passing much water. The dam is designated as a high hazard dam because of the number of residences downstream of the dam that could be impacted should a catastrophic failure occur.
