October 2026

To Our Housatonic River Neighbors,

On the weekend of Oct. 10-11, the New Haven Rowing Club will host the Head of the Housatonic Regatta. Thanks to countless hours of volunteer time, and with the support of police, fire and emergency services professionals in Shelton and Oxford, this event has grown to become a major regatta on the regional rowing calendar.

We recognize that this event affects you, and we sincerely thank you for your patience. We will have volunteers on the water on Oct. 8-9 to install the racecourse, so we ask that you be mindful of their presence. On Oct. 10-11, the river is a no-wake zone for the safety of the racing crews from 8:00 a.m. – 3:00 p.m. Saturday, and 8:00 a.m. – 5:00 p.m. Sunday. We will do our best to remove the racecourse buoys before nightfall Sunday.

Please note that you can expect heavier than usual vehicle traffic on Route 110 on race weekend, especially as boat trailers enter Indian Well State Park in the morning and leave in the late afternoon. If you are on the Shelton side of the river and are making travel arrangements for that weekend, you may experience brief delays.

Thank you so much for letting us share this special stretch of water with these athletes and their families and friends. You can get more information and find links to the regatta schedule online at https://www.newhavenrowingclub.org/head-of-the-housatonic. If you have specific questions about regatta operations or any other subject, please write to [email protected], and we will get back to you promptly.

Sincerely,

Kevin Manning
President

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.

For more information, please see the DEEP Boating AIS Stamp FAQs website at: https://portal.ct.gov/DEEP/Boating/FAQs/FAQ-AIS-Stamp or email the Boating Division at [email protected].

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
