This is a Performance Work Statement for the Control of Variable Milfoil project at Hopkinton-Everett Lakes in Hopkinton, New Hampshire, issued by the U.S. Army Corps of Engineers.

The document establishes objectives for aquatic invasive species management at two treatment areas: Elm Brook Pool (Treatment Area A) and Everett Lake (Treatment Area B). The work involves controlling variable milfoil, an invasive aquatic plant, across approximately 458 acres in the Elm Brook Pool area and 148 acres in Everett Lake. Both water bodies are classified as warmwater fisheries with trophic level MESO and maximum depths of 25 feet and 18 feet respectively. The project area includes boat launch access points at Elm Brook Pool and Clough State Park for Everett Lake. The statement includes detailed area maps showing lake locations, bathymetry, access sites, and treatment maps identifying the specific geographic boundaries for the 2026 treatment activities. The contractor will be responsible for implementing control measures within the designated treatment zones to manage the invasive milfoil species and restore ecological balance to these U.S. Army Corps of Engineers-managed water resources.
