Aquatechnex has completed contracted treatment efforts for ISDA’s program for 2018. We will resume at their direction in the spring of 2019.
We plan to be posting affected areas of the lake on Tuesday of this week and treating on Wednesday, August 8th. Please review the treatment map at this link Treatment Map
As you can see there are three areas to be treated. Those areas and within 600 feet of those areas are the only zones affected by water use restrictions. There have been some questions from those well outside the treatment areas about restrictions. If you are not within the treatment area, or 600 feet either side of the treatment area, no water use restrictions are in place.
The signs posted on affected properties on Tuesday will indicate water use restrictions as will the notices that have been sent.
ISDA has directed Aquatechnex to treat the areas in Cocolalla Lake outlined on this map. August 2018 EWM Treatment Map
This work is forecast for the week of August 6th with a target date of that Tuesday. We will update this as it gets closer. Certified Mail has been sent to each water right holder within the treatment zones and a short distance in each direction. Regular mail has been sent to all others within the treatment zone.
The product to be applied will be diquat herbicide. There are no fishing restrictions and no federal swimming restrictions, we recommend staying out of the water for 12 hours post treatment to let the herbicide dilute to the target concentration. There are restrictions on the use of water from the treatment area for irrigation and potable water use for 3 days.
The treatment program for Cocolalla Lake has be delayed slightly based on survey work performed by the Idaho State Department of Agriculture. They are finalizing maps and will have treatment information available in the near future. Check back regularly, thank you.
The Idaho State Department of Agriculture Eurasian Milfoil Control program for 2018 will begin in July of this year. The contractor, Aquatechnex LLC will be maintaining this page to provide you with additional information and treatment maps. It is anticipated that the initial work this summer will occur the week of July 9th and public notification procedures will begin late this week (June 18th)
Check back often as treatment maps will be posted when approved by the Department.
