City and County treat Lake Stevens
The City and County will again be performing an alum treatment to Lake Stevens to address phosphorus pollution in the lake. The alum removes phosphorus from the water and holds it in the lake bottom to help prevent algae blooms. The application is expected to take place between the 12th through the 23rd of May 2014.
If weather permits, the application should be completed the first week but could extend into the following week. The application is being performed under a State Department of Ecology permit and there are no restrictions to the use of the lake during or after the application which includes swimming, fishing, and water craft usage.
During the application, Caution signs will be posted at public access locations to notify residents. The signs will remain at least two days following the last application date.
The Alum application will be staged from the Wyatt Boat Launch and possibly from North Cove Swim beach. During operations at the North Cove Swim beach, the park will be closed to the public.
Distribution of the alum into the lake will be performed using a Global Positioning System (GPS) on the application boats to help ensure even coverage. Due to the size of the lake, each boat will need to make multiple trips to load alum and move back into position. To obtain the best results, the application needs to be performed quickly.
To accomplish this, during application AquaTechnex will be allowed to produce wake in the no wake zone of North Cover during all hours of operations.
This is the continuation of an on-going process to control the phosphorus condition in the lake. In addition to this treatment, the City, County, and the Snohomish Conservation District will be offering a public outreach program to educate residents on how they can do their part to reduce the excessive inflow of phosphorus into the lake.
