Water Safety in Connecticut

In Connecticut, the safest plan is simple: swim at a state park beach while lifeguards are on duty in summer, name a Water Watcher for every child, and put young or new swimmers in a life jacket. Lifeguard coverage and water testing both stop after Labor Day, so late-season swims carry more risk.

Connecticut drowning and boating numbers

0.78 per 100,000

• Drowning: CDC puts Connecticut's average annual drowning death rate for 2018-2021 at 0.78 per 100,000 people (opens in a new tab), in its lowest map band. A low rate is good news, not a reason to relax.
• Boating: The U.S. Coast Guard counted 35 reportable recreational boating incidents in Connecticut in 2024, with 8 deaths and 19 injuries (opens in a new tab). Deaths by year: 3 in 2020, 7 in 2021, 9 in 2022, 6 in 2023 and 8 in 2024.
• Coast: NOAA lists 618 miles of official shoreline (opens in a new tab) for Connecticut along Long Island Sound, its bays and tidal rivers.

CDC counts drowning deaths of residents; the Coast Guard counts all deaths in reported boating incidents. They measure different things. More on our Connecticut data page.

State park beaches: lifeguards and water testing

The Connecticut Department of Energy and Environmental Protection (DEEP) runs a seasonal lifeguard program. In 2026 it recruited 77 lifeguards (opens in a new tab), enough to cover the most popular swimming areas. Coverage shrinks at the end of summer as lifeguards go back to school. Over Labor Day weekend 2026, guards worked only at Hammonasset Beach, Rocky Neck, Indian Well, Silver Sands and Squantz Pond state parks. From September 8, no lifeguards were on duty at any state park swimming area (opens in a new tab).

DEEP also tests water at all 21 designated swimming areas during the peak season (opens in a new tab), Memorial Day weekend through Labor Day, for indicator bacteria. After Labor Day, testing is suspended and swimming is at your own risk. Check DEEP's State Swimming Area Water Quality Report before you go in summer, and read is the water safe to swim in?

DEEP's water safety tips

DEEP's advice for anyone in or near the water:

• Children should be actively supervised by a parent/caregiver at all times when around water (opens in a new tab). Name an adult as the Water Watcher, and have that person stay in the water with children who are swimming.
• Know your limits: your swimming ability, fitness and any medical conditions.
• Don't use alcohol or drugs. Their effects on balance and judgment are worse in sun and heat.
• Drink water, especially on hot, humid days.
• Children, non-swimmers, and inexperienced swimmers should wear a U.S. Coast Guard-approved life jacket (opens in a new tab).

Our guide to supervising kids around water shows how to hand off the Water Watcher job between adults.

Connecticut boating rules

DEEP says you need a Connecticut boating certificate to operate any boat with a motor, or a sailboat 19 1/2 feet or longer (opens in a new tab), if you are a Connecticut resident, own property in the state, or have a Connecticut-registered boat. Personal watercraft operators need a separate Certificate of Personal Watercraft Operation, or a recognized certificate from another state.

Federal law requires children under 13 to wear a life jacket on a moving boat (opens in a new tab). This is a summary, not legal advice; check DEEP before you go.
