LSCA Announces 2018 Milfoil Treatment

In cooperation with Josh Mulhollem from the Vermont Department Of Environmental Conservation and SOLitude Lake Management (SLM), the Lake St. Catherine Association would like to inform the community that the lake will be treated for milfoil on Monday, June 18th, 2018.

On May 9th, biologists from SLM visited the lake to perform a milfoil survey. They have identified areas to be treated with aquatic herbicide Renovate and Renovate OTF in Accordance with the Aquatic Nuisance Control Permit #2014-C01.

Please see the full advisory notice and map of the herbicide treatment areas by clicking here.

During and after the treatment, please be aware of the following lake water use restrictions:

• There shall be NO USE of Lake St. Catherine, Lily Pond and Little Lake FOR ANY PURPOSE, including boating, fishing, swimming, domestic (household) use or irrigation, on the day of and the entire day after the treatment

• Swimming/wading, boating, fishing and domestic use (except drinking or for food or drink preparation) may resume the beginning of the second day following treatment.

• Use of water from Lake St. Catherine, Lily Pond and Little Lake for drinking or for food or drink preparation shall not resume until water sample analyses reveal that the active ingredient in Renovate (triclopyr) is at or below 75 parts per billion by laboratory analysis.

• Use of water from Lake St. Catherine, Lily Pond and Little Lake for irrigation, including use for watering lawns, trees, shrubs or plants, shall not resume for 120 days or until water sample analyses reveal that triclopyr is at or below 1.0 part per billion by laboratory analysis, whichever comes first.

This means that the lake will be closed for all uses on Monday, June 18th and Tuesday, June 19th.

Along with the herbicide treatment, 13 areas have been selected for DASH. DASH is an acronym for Diver Assisted Suction Harvesting. This process involves scuba divers using suction hoses powered by a surface compressor to selectively remove milfoil from the lake bottom. They will be working throughout the season to remove milfoil by the roots in these designated areas.

Here is a map of the treatment areas for Renovate and DASH:
