(HARTFORD) – The Connecticut Department of Energy & Environmental Protection (DEEP) reminds boaters to purchase an Aquatic Invasive Species (AIS) Stamp ahead of enhanced enforcement efforts over Labor Day Weekend. Anyone who operates a motorboat or personal watercraft on Connecticut’s inland waters, including the designated inland waters of the Connecticut, Housatonic and Thames Rivers, is required to purchase an AIS Stamp. The AIS Stamp can be purchased through DEEP’s online Sportsmen Licensing System or wherever fishing licenses are sold.

An AIS Stamp annual purchase is required for both Connecticut residents and out-of-state visitors operating a registered vessel on Connecticut’s inland waters.
