In January 2020, the State of Connecticut began collecting an Aquatic Invasive Species Stamp fee from anyone who registers or renews a registration of a boat, vessel, or jet ski in Connecticut.

Boaters with out-of-state registrations who boat on Connecticut inland waters will also be required to pay this fee. Monies collected go into the Connecticut Lakes, Rivers, and Ponds Preservation account for grants that support the restoration and rehabilitation of lakes, rivers, and ponds.

The legislature in 2022 established an Office of Aquatic Invasive Species within the Connecticut Agricultural Experiment Station.

Gateway Commission Activity

From 2016 to 2018, the Commission successfully partnered with the US Fish and Wildlife Service, the CT Department of Energy and Environmental Protection, The Nature Conservancy and private citizens to rid Ely’s Marsh in Lyme of extensive stands of invasive Phragmites.

In 2018, the Gateway Commission provided a grant of $20,000 to assist in the surveying of invasive in-water invasive plants in the Zone to identify where they are growing. This survey has led to important baseline information that will be used as the efforts to learn how to control and eradicate these invasive plants moves forward.

DID YOU KNOW?

How long did you say?

In the 1970s, a bridge was proposed that would extend from Old Saybrook to Long Island. That would be roughly ten times as long as the Golden Gate Bridge. Residents and officials in eight river-front towns decided that the Connecticut River Gateway Commission and the Zone were needed as protection against unbridled development.
