Beaches are sometimes closed due to excessive rainfall
Based on studies by the Westchester County Department of Health, heavy rainfalls in the watershed of the Mamaroneck River greatly impact the quality of water in the Mamaroneck Harbor. Echo Bay in New Rochelle is similarly affected impacting Hudson Park Beach and Echo Bay Yacht Club.

Beach closures are based on the number of inches of rain on the watershed. Heavy rains and discharges from stormwater drains directly affect these waters. As a result, these waters may contain high levels of harmful bacteria that may cause illness after a heavy rain.

Threshold levels have been established to promote a guide for the closing of beaches located within the protected area of these harbors.

  • Greater than 1/2 inch of rain = 1 day closure
  • Greater than 1inch of rain = 2 day closure
  • Greater than 2 inches of rain = to be determined

If you plan on going to any of these beaches after a rainfall, check to make sure they are open by calling the beach.
