Clarks Creek Elodea Management

Management of the overgrown elodea in Clarks Creek has been on-going for more than 20 years in Puyallup. In 2012 a task force comprised of staff, Council, citizens, regulatory agencies, and other organizations worked together to develop agreeable solutions to the problem. The goal was to find sustainable solutions that would reduce the overall presence of elodea and sediment in Clarks Creek, improving the health of the creek.

Beginning in 2013, Puyallup implemented the solutions identified by the Task Force and is now working toward a future for Clarks Creek that is not impacted by elodea and sediment loads. Read about the Clarks Creek Task Force process and projects underway by Puyallup's Stormwater Section.

Diver-Assisted Suction Harvesting (DASH) and the 2012 Clarks Creek Task Force

Diver-assisted Suction Harvesting (DASH) was identified by the 2012 Elodea Task Force as the main method for elodea removal starting in 2013 onward. In this process, divers enter the water from pontoon-type boats, using surface-supplied air. The divers hand-pull the elodea from the stream, and feed it into a suction hose. The plant material is suctioned to the surface of the water, into mesh bags located on the boat. When several bags are full, they are each transported to the shore, and removed from the project site. This process reduces the fragmentation of the elodea, and completely removes the plant from the stream so it cannot re-plant itself, or grow back. This process is modeled after similar successful DASH projects in Thurston County, WA and New York. Permit applications for the 2013-2018 DASH project included: •Shoreline Substantial Development Permit (City of Puyallup) •State Environmental Policy Act project review (City of Puyallup) •Hydraulic Project Approval, HPA (WA Fish & Wildlife) Also planned for the 2013 project was removal of accumulated rocks under the 56th Street E and Stewart Ave E bridges. It is believed these rocks were pushed into thewater over the years by vandals, creating a restriction to the creek flow at those locations.
