First Hayden Lake Treatments set for Monday/Tuesday next week


Aquatechnex will be starting aquatic herbicide treatments targeting Eurasian Milfoil on Hayden Lake this coming week (July 9-10).  These treatments will be made at the three sites on this map First Hayden Treatment Map.

The Monkins Bay Site will be treated on Monday July 9th and signs will be posted today on all affected properties.  The other two sites north and south of Monkins will be posted on Monday the 9th and treated on Tuesday the 10th.

The product to be used is Littora Aquatic Herbicide.  There is a three day restriction on the use of treated water for drinking and irrigation from the treatment sites.  While there is no swimming restriction on the US EPA label, we recommend staying out of the water for 12 hours as a precaution to allow the concentrate to dilute and be absorbed by the target vegetation.

Any questions can be addressed to ISDA at 208-332-8667 or you can leave a comment here.

Please note that there will be a second round of treatments the week of July 23rd and public notice is going out this week regarding that.  Updates will be posted on that treatment after this is completed. 


Treatment Planned for the Week of July 9th

The first Eurasian Milfoil treatment on Hayden Lake is scheduled for the week of July 9th.  The anticipated work flow will be posting the treatment areas on Monday the 9th and performing the application on Tuesday the 10th weather permitting. Please check back during that week and get updates here in cases the schedule changes slightly.

The blue polygons are the treatment zones where herbicide will be applied, the yellow buffer zone is the area where water use restrictions apply.

2018 Eurasian Milfoil Treatment Program

We will be using this site to communicate with the public during the 2018 Eurasian Milfoil Control Program.  Aquatechnex will be performing treatments at the direction of the ISDA program and this location will include updates, interactive treatment maps and other key information during this summer.

Initial plans are to treat areas identified by survey the week of July 9th and additional treatments scheduled for the week of July 23rd.

Stop back often for treatment information.
