Water in Lake Tapps will rise about four inches to roughly 543 feet by Sept. 26.
That will bring the popular East Pierce County reservoir – which is owned by Cascade Water Alliance – to full recreational level, showing “both the homeowners and Cascade what the water level will be when Cascade is providing municipal water supply,” the group wrote in a news release.
Immediately after the water goes up, it will be brought down to about 542.5 feet, and will remain there through October, Cascade said.
Then the drawn down for winter will begin, Cascade said, adding it will notify homeowners when the water is at its lowest.
Cascade, a consortium of King County cities and water districts, bought Lake Tapps to eventually use as a regional source of drinking water.
