2013 Clark's Creek Elodea Management


Diver-assisted Suction Harvesting (DASH) was the main method for elodea removal planned for 2013. 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 was modeled after similar successful DASH projects in Thurston County, WA and New York.

Permit applications included for the 2013 in-stream work window in the DASH project include:
  • Shoreline Substantial Development Permit (City of Puyallup)
  • State Environmental Policy Act project review (City of Puyallup)
  • Hydraulic Project Approval, HPA (Washington Fish and Wildlife)
Also planned for the 2013 project was removal of accumulated rocks under the 56th Street E and Stewart Avenue E bridges. It is believed these rocks have been pushed into the water over the years by vandals, creating a restriction to the creek flow at those locations.

2013 Project Details


The in-water work window for 2013 was June 17-August 14 - discussions with the Puyallup Tribe of Indians and positive results from the in-water work have resulted in the Tribe granting a 13-day extension of in-water work, into August in support of completing a fully-managed project area. The elodea management in 2013 was to be completed primarily by a Diver-Assisted Suction Harvesting (DASH) method. The work began in targeted areas of the creek, and generally work in a downstream direction. Below are daily summaries of the work progress as well as to maps and exhibits of the project:
