Taiga Wetlands - Green Lake Floating Ecosystem Demonstration Project Update

SUCCESS!

Taiga Wetlands were successfully installed on Saturday May 28, 2022 by a team of about 40 volunteers. It was an incredible accomplishment to transport, assemble, plant, launch, and anchor the two 680 square-foot floating wetlands in One Day by volunteers who mostly had not done this nor even seen floating wetlands before. You can see them anchored west of Duck Island along with all the nesting ducks and resting great blue heron.

Many thanks go to Galen Fulford from Biomatrix Water for making the trip from Scotland to direct our efforts, which could not have been done without the hard work by our volunteers and with inspiration from Taiga. Be sure to see the project newsletter by Biomatrix with photos and a 1-minute video of the installation.

A huge thanks to Sean Hermes and Seattle Parks and Recreation staff for storing and transporting the wetland materials to the lake, supplying wood chips and gravel, and providing foot traffic control during installation. We are thankful for Go Natives Nursery! providing most of the 1,090 plants at a great price and for being able to more than double our order on a Saturday when we realized we had greatly under-planned plant density. Thanks to Taiga’s family for supporting volunteer efforts and to the many Herrera staff who contributed to project design, planning, and installation.

This project was made possible by many private donations and a $50,000 grant from the Seattle’s Neighborhood Matching Fund.  We need to raise about $6,000 more to supplement our material costs and provide sufficient funds for long-term maintenance and monitoring. Please help fund our project by contributing a tax-deductible donation using our Venmo account or mail us a check.

Green Lake Water Quality - Sept. 25, 2022

Secchi Depth: 1.3 meters, (4.3 feet)
Water Temp: 15.0 C, (59.0.F)
Lake Water Quality is monitored weekly by Jeffrey Howard at East Green Lake from the T-dock near the Green Lake Community Center or from a boat at the deepest part of the lake. The weekly data are reported quarterly and uploaded to the King County Lakes website available here. Select “Green-1” and “View Data”. General lake information, water quality data, and reports are available here.

For continuous Green Lake Water Level and Temperature Gauge data tracked by King County, go to the King County Hydrologic Information Center website where you can search for both temperature (in C) and lake elevation. Here are instructions:
1. Click on either Water Temperature or State Only Gage to get a map of monitoring sites.
2. Click on the red dot at Green Lake
3. Click on View Graph. (The graph is currently being updated to improve visibility.) More data selections are listed left of the graph.

Spring 2022 Green Lake Trout Plant

A favorite family activity enjoyed at Green Lake over the years has been fishing.

On April 27, 2022 Green Lake was planted with 4,851 catchable-size trout weighing a total of 10,187 pounds. For lake trout stocking reports see the WSFW website: https://wdfw.wa.gov/fishing/reports/stocking/trout-plants?lake_stocked=GREEN+LK+%28KING%29&county=&species=&hatchery=&region=   This is a typical amount that is planted in the lake each spring, with the exception of an unusually high amount of 45,000 pounds in 2014 due to a surplus of large hatchery trout that year.

While trout are fun to catch, trout stocking may increase the amount of algae (measured as chlorophyll-a) in the lake due to their consumption of algae-eating zooplankton and their additional nutrients, as indicated by this graph. For a detailed study on the effects of trout stocking on algae blooms in Washington lakes see the report by Herrera Environmental Consultants: https://www.herrerainc.com/publications/trophic-cascade-effects-on-algae-blooms-in-washington-state/

Green Lake Beach Bacteria Monitoring

Studies Show Water Quality Impacts of Homeless Waste Disposal at Green Lake

Statistical analysis of weekly fecal bacteria data shows a significant increase in levels at West Beach but not East Beach in the past 2 years. This finding suggests that the increase may have been due to human waste disposal in the lake since West Beach is down current of homeless encampments and RVs, while East Beach is not near encampments and was closed to swimming and more populated by geese in this period. Human waste pathogens and floating hypodermic needles pose a risk to swimmers on the west shore of the lake.
