DEEP Requests Proposals for Grants for Aquatic Invasive Species Control on Lakes, Ponds, and Rivers
Applications Due December 10
(HARTFORD) – The Connecticut Department of Energy and Environmental Protection (DEEP) is now accepting proposals for the Aquatic Invasive Species (AIS) Grant Program for 2026. Applications will be accepted through December 10, 2025. Please visit the DEEP AIS Grant Program website for details on how to apply for 2026 grants.
In 2019, the Connecticut General Assembly created dedicated funding to address AIS via Public Act 19-190, which established an AIS Stamp and associated fee that applies to all registered boats using Connecticut inland waters. Funds derived from the AIS Stamp are distributed via a competitive AIS Grant Program, funding selected projects proposed by municipalities, state agencies, and non-profit organizations to address the impacts of AIS on inland waterbodies in Connecticut. DEEP has awarded approximately $1.9 million to 71 projects during the first five years of the AIS Grant Program.
Invasive species, such as hydrilla and zebra mussels, are a serious threat to freshwater ecosystems and outdoor recreation. Invasive species can negatively affect native plants and animals, and the dense mats formed by invasive aquatic plants can seriously hamper boating, fishing, and swimming. These species often are costly and challenging to eliminate once established, necessitating intensive control and education efforts to prevent further spread.
“Boating and fishing are the largest contributors to Connecticut’s outdoor recreation economy, which continues to experience year-over-year growth and outpaces the national average,” said DEEP Commissioner Katie Dykes. “Aquatic invasive species pose a serious threat to that economy and to the health of our freshwater ecosystems. The funding provided by our AIS Grant Program will enable grant recipients to do the critical work of controlling and researching aquatic invasives, helping to protect the state’s waterways and preserve the many benefits they provide to residents, visitors, and local communities.”
DEEP urges all boaters to help prevent the spread of AIS by carefully inspecting their boat and trailer for aquatic vegetation before and after every launch. It’s Connecticut law that no person shall transport a vessel or any trailer used to transport such vessel in Connecticut without first inspecting such vessel for the presence of vegetation and aquatic invasive species and properly removing and disposing of any such vegetation and aquatic invasive species that are visible and identifiable. Any person who violates these provisions shall be fined up to $100 for each violation.
Reminder about changes to the AIS Stamp
DEEP reminds boaters that due to the Connecticut General Assembly’s 2023 passage of Public Act 23-154, the AIS Stamp fee no longer is collected by the Connecticut Department of Motor Vehicles (DMV) at the time of vessel registration but instead is collected by DEEP. Effective October 1, 2024, Connecticut residents or non-residents operating a vessel on Connecticut’s inland waters must purchase a $7 Individual AIS Stamp or a $20 Vessel AIS Decal which must be permanently affixed to a vessel (AIS Decal may be subject to an additional processing fee).
Both the Individual AIS Stamp and the Vessel AIS Decal can be purchased via the Online Sportsmen Licensing System and are valid until the end of the calendar year in which they are purchased. Individuals operating a vessel on Connecticut’s inland waters who do not possess an Individual AIS Stamp and are operating a vessel without a Vessel AIS Decal affixed are subject to a fine of $85.
For more information on the changes to the AIS Stamp and instructions on how to purchase the Individual AIS Stamp or Vessel AIS Decal, please visit the DEEP AIS Stamp Frequently Asked Questions (FAQ) website.- Twitter: @CTDEEPNews
