2015 Project

2015 Clarks Creek Elodea Management


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.'

Running Totals


  • Total
    Area Cleared: 16225 LF
  • Total elodea removed: 9030 bags
The regular-season elodea management completed on July 7, 2015, 3.5 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 rework was completed on July 17, 2015.

The change order effort is expected to be completed by July 17, 2015, still ahead of the 2015 schedule.
