Update July 23rd

We have received a question regarding upcoming.  The way the Washington Department of Ecology permit is developed, we are required to provide residents notice of treatments and we generally create a few different treatment windows so we don’t have expend your funds to notify people a number of times over the summer.

There is no treatment scheduled for the week of August 1st.  We plan to do survey work on the lake during this week to review conditions, the results of the first treatment, any need for touch up etc and will be in communication with your board in this regard after that has occurred.

Eurasian Milfoil Treatment Tomorrow Tuesday June 28th

Aquatechnex biologists will be treating portions of Loon Lake tomorrow Tuesday June 28th with aquatic herbicides to target Eurasian Milfoil.  Areas that have been identified with milfoil infestations are shown on the map page you can access by clicking on that link above.  There are water use restrictions that will be in place as the treatment is performed.  Renovate herbicide will be used, it is a granular product.  There is a 24 swimming precaution that applies only to those areas mapped.  There is also a short restriction on use of the water from these treatment areas for irrigation or potable uses that generally last 3-5 days.  We will post the all clear here when sampling shows levels down.

The team will be posting signs on affected properties tomorrow morning at your shoreline or dock and treatment will begin shortly after that.  They should be clear of the lake by mid afternoon if all goes well.

Please note that water use restrictions only apply within the areas on the map, please review that map to see if your property is affected.  We will not be posting properties that are outside the treatment area.

 

 

Treatment Update

Portions of Loon Lake will be treated with Aquatic Herbicides to combat Eurasian Milfoil early this week.  At this point the plan is to travel to Loon Lake on Monday afternoon, posting of the lake will be performed Monday evening or Tuesday morning depending on the team’s arrival.  Please refer to the treatment map link on this page to locate your home and determine if you are in the treatment area.  We will update this site tomorrow but treatments are expected to occur on Tuesday.

Public Notices Arriving at Your Home

You will in short order be receiving a notice from Aquatechnex regarding this year’s Loon Lake Eurasian Milfoil Control Program.  This notice is a form that the Washington Department of Ecology Permit requires and it provides information that they specify.

We have just completed the early summer survey of the lake, and we will be posting an interactive map here in the next day or so.  The purpose of this map will be to allow you to see where the actual treatments are in relationship to your home or cabin on the lake.  The treatment polygons will also have a “buffer” around them, this will visibly show you where the water use restrictions are in place after the treatment.

We will be using a Color Code system to help you understand treatment restrictions.  Prior to treatment, the polygons where the herbicide will be placed will be colored yellow.  On the day of treatment, the color will change to red signifying that treatment has occurred and restrictions are in place.  When the sampling shows restrictions can be lifted, we will change the color again to green.

You will be able to zoom in and out, locate your property and see where you are in relationship to actual treatments.  We will also be posting signs on your shoreline just before treatment.

Update on Summer Work, 2016

Aquatechnex biologists visited the lake and toured the shoreline to determine if the aquatic plant growth in the lake was ready to perform a full blown aquatic vegetation survey.  We observed areas of fairly dense Eurasian Milfoil and expanding populations of Curly Leaf Pondweed, another invasive aquatic weed that seems to be on the march in the lake. Based on this evaluation we intent to complete a survey of the lake in the next two weeks and report this to the Loon Lake LMD Board.

We will be using a hydro-acoustic mapping system initially to detect and map the shapes and density of the aquatic plant communities present in the lake.  We will then visit these zones and determine if there are noxious aquatic weeds present at densities that required treatment.  We anticipate performing the first treatments before Fourth of July weekend and we will have maps available here as well as additional information on the treatments.
