    • CO-OPS Water Level Data from the Coastal Tide Gauge and Great Lake Water Level Network of the United States and US Territories

    Metadata Updated: June 8, 2022

    The Center for Operational Oceanographic Products and Services (CO-OPS) of the National Ocean Service (NOS), an organizational element of NOAA, operates and maintains a network of approximately 200 long-term National Water Level Observation Network (NWLON) stations as part of the National Water Level Program (NWLP) for the United States coasts and in the Great Lakes. CO-OPS also installs and operates short-term water level stations in support of a variety of programs including hydrographic surveys, marine boundary determination, tidal predictions, habitat restoration, dredging, climate change, and long-term sea level rise studies. The data collected and predictions derived are used to ensure safe,efficient, and environmentally sound maritime commerce, environmental assessment, and hazard mitigation. CO-OPS provides a set of water level products required by NOAA's National Weather Service (NWS) to meet flood and tsunami warning responsibilities. Included in this water level collection are preliminary 1-minute, preliminary 6-minute, verified 6-minute, verified hourly, verified highs and lows, verified daily means, and verified monthly mean water levels.
