For 20 years it has been Friends of the Bay's mission to preserve, protect and restore the ecological integrity and productivity of the Oyster Bay/Cold Spring Harbor estuary and the surrounding watershed.

Welcome to the Oyster Bay Estuary Water Quality website - a key tool in our mission to monitor and protect the Oyster Bay/Cold Spring Harbor estuary and the surrounding watershed.

This site contains a wealth of information on what we are doing, what we have done and what we will be doing in the near future.

Our Monitoring Program:

  • Provides high quality data to continue the dissolved oxygen-testing baseline established by Nassau County's Department of Health in 1972.
  • Screens for water quality impairments.
  • Monitors the estuary in support of the Total Maximum Daily Load (TMDL) for pathogens that has been established for Oyster Bay and Mill Neck Creek.
  • Determines long-term water quality trends.
  • Documents the effects of water quality improvement programs.
  • Educates and involves citizens and public officials about water quality protection.
  • Watchdogs activity within the watershed and harbor.
  • Assists local, state and federal agencies in harbor management.
