The Challenges of Milfoil

Milfoil has posed environmental and maintenance challenges for Lake Tapps. Over the last several years Cascade has worked to control milfoil growth, and has removed a large portion of this invasive plant. Cascade will continue to monitor and follow up with appropriate treatment during growing seasons. According to the Washington State Department of Ecology (DOE), milfoil starts spring growth earlier than most native aquatic plants and can out compete these beneficial plants. Because it is widely distributed and difficult to control, DOE says milfoil is considered the most problematic plant in Washington State.

Native Aquatic Plants

Due to a decrease of milfoil, and a general decrease of inflows and outflows, many areas of Lake Tapps have experienced an increase in native aquatic plants.  Native aquatic plants are important to the health of any lake system and Cascade is not planning to remove native plants at Lake Tapps. Please Contact Pierce County, Bonney Lake, or the Washington State Department of Fish and Wildlife, before removing native vegetation from the shoreline or lake bed. Below are several native aquatic plants that were found in Lake Tapps during our spring 2014 survey:
