Long Island Sound Clamming FAQ

Always call the town hotline before you go. Bed status changes after rain and for other public-health reasons, and the hotline (not this page) is the authoritative answer.

Is Long Island Sound clamming open today?

This site cannot tell you a bed is open, and never marks one as open. Status changes daily after rain and for biotoxins, Vibrio, sewage or administrative reasons. In Connecticut, only the Department of Agriculture Bureau of Aquaculture opens or closes beds, and the state says to call the hotline daily before harvesting (CT DoAg hotlines ↗). In New York, NYSDEC posts temporary closures online (NYSDEC closures ↗) and on its recorded line 631-444-0480.

Every hotline, one tap: hotline table. Always call the town hotline before you go.

Do I need a permit to go clamming in Connecticut?

Connecticut does not sell one statewide recreational shellfish license. Each shoreline town (or its shellfish commission) issues its own permit, sets its own fees and posts its own rules. Harvest is allowed only in Approved and Conditionally Approved areas that are currently open, never in leased or franchised beds (CT DoAg ↗). Fees and sellers by town: Connecticut permit guide. Always call the town hotline before you go.

How long do shellfish beds stay closed after rain?

  • Fairfield: rainfall closures typically last at least 7 days.
  • Greenwich: Areas A and B close after >1.5″ in 24 h, for 8 days.
  • Niantic River: at least 7 days, with water samples after 5 days.
  • Connecticut statewide: any area closed for rain or sewage stays closed at least 7 days and reopens only after satisfactory state testing (CT DoAg FAQ ↗).
  • New York: NYSDEC: emergency closures follow rainfall over 3" in 24–36 hours. In summer, when water is warmer, some areas may be closed after LESS than 3". Closures may be extended beyond 7 days if water quality has not improved by day 6. North Shore embayments close at least 3 days and may reopen on day 4 after testing (Stony Brook and Mount Sinai harbors may take longer). Recorded closure line 631-444-0480, updated after 4 PM from day 3–4. (NYSDEC rainfall criteria ↗)

Can I go clamming in Bridgeport, New Haven or Old Saybrook?

We found no recreational shellfishing program or public bed in any of the three:

  • Bridgeport: the state atlas classifies all of Bridgeport’s waters as Prohibited or Restricted-Relay.
  • New Haven: the shared Conditionally Approved area is offshore, with Restricted-Relay and Prohibited water in the harbor. No city recreational permit, map or rules were found.
  • Old Saybrook: the state atlas classifies all of Old Saybrook’s waters as Prohibited.

Do not harvest unless the town or the state tells you a specific area is open to the public. Ask the CT DoAg Bureau of Aquaculture at 203-874-0696. Nearby towns with programs: Fairfield, Milford, Branford, Clinton. Always call the town hotline before you go.

What does conditionally approved mean?

Most recreational shellfish beds on Long Island Sound are “conditionally approved”: they are open only while water quality is good, and they close automatically after heavy rain, because runoff can carry bacteria and shellfish filter the water. Regulators set a rainfall trigger; once it is crossed, the bed closes for a fixed minimum time and reopens only after testing or the end of the closure period (CT DoAg ↗). A conditionally approved classification on its own does not create a public recreational area, since grounds are often leased or franchised. Always call the town hotline before you go.

What are the best tides for clamming?

Most recreational clamming happens around low water, and Branford notes low tide in warm weather is easiest (Branford ↗). See the tide clock (NOAA CO-OPS predictions). Tides are not a status indicator: beds can be closed at any tide. Many towns also allow harvest only between sunrise and sunset; check your town page. Always call the town hotline before you go.
