Aquatechnex will be performing the first application of Sonar Aquatic Herbicide to Lake Tapps the week of August 30th.
This work is governed by a permit from the Washington Department of Ecology. That permit requires us to post signs on each property prior to treatment so that the community knows it has occurred in waters adjacent to their property. Sonar will be applied to all of the red and orange areas as mapped on the treatment map page above.
We plan to perform the sign posting on Monday August 30th. These signs will only be placed on your dock or shoreline if you are in the treatment area or within Ecology’s required buffer zone. We plan to make the actual application of the material on Tuesday August 31st starting in the early morning. This application will take approximately one day to apply.
Information on Sonar is presented in the article below. There are no restrictions on the use of the treated water for swimming or fishing. There is an irrigation precaution if you draw water from the lake for that purpose.
Questions should be addressed to us through the log a case page above.
