Control Grants for Exotic Aquatic Plants
Grants are awarded to local lake associations and municipalities for the control and treatment of exotic aquatic weeds, like milfoil. NHDES will pay 100 percent of the treatment costs for a new infestation, and will match up to 50 percent for repeat management practices.

Long-term management plans will be developed for each waterbody that requests funding. The management plans will be developed by NHDES with input from the lake residents and municipalities, and they will be reviewed by the Fish and Game Department and the Department of Agriculture.

The goal of the long-term plans is to develop a strategy for exotic species management over several years (usually 5 years) for specific waterbodies. Plans will include an evaluation on the infestation, maps of the waterbody, watershed, and infestation, evaluations of control options, goals for management, and a plan for carrying out the strategy that is selected. New Hampshire is striving to use Integrated Pest Management (IPM) strategies for controlling exotic plants, so that we can use the best available methods and technologies to eradicate, manage, or control infestations of exotic plants in the subject waterbody. By incorporating all of this information into one plan, it will likely expedite the review time and make the process of grant allocation and permit review more expedient.
