Today is the Day

Aquatechnex biologists will be performing the first phase of the 2017 Lake Stevens Eurasian Milfoil Treatment Project.  This phase will involve applying Renovate OTF Granular herbicide to areas of the lake noted on the map page.  We will also be returning late next week to target remaining zones with a second herbicide that the City Council approved this week.  Signs will go up on affected properties, water use restrictions are only in place within the treatment zones for today.

On the treatment map, those areas marked in Green will be treated today.  The areas marked in Orange will be targeted late next week.

Treatment map is viewable here, July 13 Treatment Map

First Treatment for Eurasian Milfoil to be Performed this week

Aquatechnex biologists have completed survey work for 2017.  Eurasian Milfoil has expanded in Lake Stevens significantly this year.  The City has elected to add some treatment areas to the budget for this project.

We will start with an application of Renovate Herbicide to the areas on the map labeled in Green this week.  Posting should occur on Wednesday evening or Thursday Morning and the treatment is scheduled to start on Thursday Morning.

The areas marked in orange will be treated with a different herbicide, Diquat.  This application will require that we notify these residents 10 days prior.  That notification will go out early this week and treatment will be performed the week of July 17th.

The treatment map is accessible here, green areas this week, orange areas next week.  Click for Treatment Map

Eurasian Milfoil Treatments

We have completed survey work and proposed a treatment plan to the City.  This year milfoil has expanded beyond what is normally targeted, so we have proposed a few different options.

The first treatment will be performed with Renovate OTF Granular the week of July 10th, we will be posting a treatment map for reference here late this week.  Depending on the City’s decision regarding expanded treatments, those will probably happen late the week of the 10th or early the week of the 17th.  Maps will be posed there as well.

Check back here for exact treatment dates later this week as well.

2017 Program about to start

Aquatechnex will be doing the initial survey work on Lake Stevens in Mid May.  The lake littoral area will be inspected for presence of Eurasian Milfoil.  If and where milfoil beds are found they will be mapped and proposed for treatment.  A notice will then go to affected homes and a treatment map with additional information will be posted here.

Summer of 2017 is coming fast

Aquatechnex biologists will begin survey work on Lake Stevens in a few weeks.  The team will be mapping locations where Eurasian Milfoil remains in the system and making treatment recommendations to the City.  Our plan is to target this growth in late May or early June this year.

The Alum treatment traditionally performed in the Spring to sequester phosphorus will be moved to the fall this year.  More information on that process will be posted as that time draws near.

Lake Stevens 2016 Alum Treatment Starts Tomorrow

Aquatechnex biologists will be conducting the annual Aluminum Sulfate treatment to the surface of Lake Stevens Tuesday through Thursday of this week.  This annual application precipitates and sequesters phosphorus that problem algae can utilize to cause bloom conditions.

The boats will be working in sectors on the lake each day focusing on one third of the surface area.  We appreciate little or no wake when possible around our vessels and please understand if your fishing that we have to “paint” the entire lake surface and that requires us to move in straight lines so if you see us coming we would appreciate leeway.

If there are any questions you may leave a comment here and we will receive and respond to it.

Planning for 2016 Alum Treatment will begin next week

Aquatechnex biologists will be working with the City of Lake Stevens to develop the 2016 alum treatment program sometime in October.  This application generally takes about 4 days and removes phosphorus from the water column to help mitigate blue green algae growth.

More information will be posed here when this project fires up.
