Eurasian Milfoil Treatment Tentatively Scheduled for this Thursday

Our team is organizing to treat portions of the lake impacted by Eurasian Milfoil this Thursday.  We will be uploading a treatment map tomorrow.  Areas to be treated will be posted on the shoreline, areas not posted are not effected.

The herbicide to be used is Renovate OTF granular.  This herbicide carries a 3 day irrigation restriction for those that draw water from the lake for this purpose.  While there is no federal swimming restriction the Washington Department of Ecology requests a 24 hour no swim precaution in the treatment areas.

Check back tomorrow for a second update.

2015 Alum Treatment Rapped Up

The 2015 Lake Stevens Alum Treatment Project was completed yesterday without a hitch.  This program removes phosphorus from the lake.  Phosphorus is the limiting nutrient for blue green algae species, these single celled organisms can pose a health threat and degrade water quality.  Removing phosphorus reduces the carrying capacity of the lake to product problem algae blooms.

2014 Eurasian Milfoil Treatments

Our summer surveys have found some areas that could use treatment to continue the reduction of this noxious aquatic weed in Lake Stevens. Tomorrow August 20th we will be delivering notices to those shoreline residents that are within a quarter mile of potential treatment areas. This is a Department of Ecology requirement. The actual restrictions on water use only apply within 400 feet of the actual treatment area so these restrictions will not impact everyone notified.

The primary restriction is on the use of lake water from the treatment area for irrigation for approximately 2-5 days. This treatment will be happening after Labor Day.

We will post more information here as well as a interactive treatment map that you can view when the treatment gets closer.
