Reminder to boaters about new aquatic invasive species stamp purchasing requirement.
As of October 2024, boaters operating a registered vessel on Connecticut’s inland waters need to purchase an AIS stamp. This includes Lake Housatonic.
To comply with the AIS Stamp law, boaters have two options:
Individual AIS Stamp ($7.00). The Individual AIS Stamp is assigned to the individual purchasing the stamp, and it allows that individual to operate in compliance. The proof of purchase is displayed on that individual’s Sportsmen Conservation License as a privilege like a hunting or fishing license.
Vessel AIS Decal ($25.00). The Vessel AIS Decal is assigned to a particular vessel, and it allows anyone operating that vessel to operate in compliance. The proof of purchase is a decal that must be affixed to the vessel. The Vessel AIS Decal also provides an Individual AIS Stamp for the purchaser which will be displayed on that individual’s Sportsmen Conservation License as a privilege like a hunting or fishing license.

Effective January 1, 2020-An Aquatic Invasive Species (AIS) Stamp fee will be collected from any person who registers a vessel or renews a vessel registration in Connecticut. Boaters with out of state registrations who boat on Connecticut inland waters will also be required to pay an AIS fee
