The owner of Lake Tapps says a milfoil infestation in the popular East Pierce County reservoir is “radically reduced” and it won’t have to conduct a widespread chemical treatment this summer.
Cascade Water Alliance has been treating the lake for milfoil, an invasive aquatic plant, since 2010, and roughly 95 percent of the milfoil recorded that first year now is gone, a news release said.
“We are extremely pleased with the success of the program and how quickly and dramatically milfoil has been reduced on the lake,” said Jon Shimada, capital projects director, in the release.
Cascade says divers will hand-pull plants this summer, and limited chemical treatment may happen if “problematic areas” are discovered. The group now will shift to “ongoing maintenance, regularly monitoring milfoil growth on the lake,” the release said.
Boaters are asked to clear their vessels of milfoil picked up at other lakes, and should contact Cascade to report milfoil in Lake Tapps, the release said.
