Herbicide Treatment Dates Set!
Boating season is here––and we’re kicking off the second year of invasive species control on the Charles!
With last year’s successful treatment of milfoil, this year the focus is on tackling fanwort in the Lakes District.
A series of Sonar treatments are scheduled for the next few weeks:
May 31, 2023
Jun 23, 2023
Jul 12, 2023
Aug 3, 2023
WHAT TO EXPECT ON TREATMENT DAYS:
DCR’s consultant, SOLitude Lake Management, will apply Sonar herbicide to 105 acres in the Lakes District, in the densest patches of fanwort. River users should plan to stay out of the way of the treatment boat during the herbicide application to allow them to work efficiently. The herbicide itself is safe for humans and would have no health effects on anyone who may accidentally come in contact with it. However, use of the treated water for irrigation will result in the death of irrigated plants.
Because the first treatment is within the herring migration season, a water quality monitoring program approved by the Department of Marine Fisheries will be implemented to ensure no impacts to migratory fish. Although milfoil regrowth after last year’s treatment is anticipated to be limited, targeted application of ProcellaCOR in the Lower Basin may be considered if growth is observed.
SUPPORT INVASIVE REMOVAL!
Removing invasive plants is a big job, and we rely on community support to meet our goal of a clean, healthy Charles!
Your gift provides the resources to help clear invasives from identified prioritized areas of the river as part of DCR’s extensive 5-year management plan.
