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.
The in-water work window for the 2015 Elodea Management was June 1-August 1. With a record-setting volume of elodea able to be removed in 2014, and a consideration for the time when the elodea really starts to 'bloom out', the City requested and was granted approval by WDFW and the Puyallup Tribe to begin in-water work on June 1 in an effort to pull the elodea before it hits its massive 'bloom out'.
Total area cleared: 16225 LF
Total elodea removed: 9030 bags
The regular-season elodea management completed on 07/07/2015, three and a half weeks ahead of schedule, and with only 30% of the volume needed to be removed than in the 2014 season. As a result of the under-budget and ahead-of-schedule contract work, the City negotiated a change order with the contractor to re-visit an area of the creek completed earlier in the season. As has been observed in various areas of the creek, this area had experienced sediment transport since the earlier pull which has uncovered spots of previously-buried elodea. This re-visit effort further supported a reduction in the elodea regrowth for 2016.The re-work was completed on 07/17/2015.
The change order effort is expected to be completed by 07/17/2015, still ahead of the 2015 schedule.
