Data

SWaTH is a system of flood-hardened, real-time telemetered tide gages, rapid deployment gages, and storm tide sensors deployed in integrated network configurations along the Northeastern Atlantic Coast from North Carolina to Maine.

WaterWatch is a U.S. Geological Survey (USGS) World Wide Web site that displays maps, graphs, and tables describing real-time, recent, and past streamflow conditions for the United States. 

The USGS operates an event-based mobile storm-surge sensor network to capture information about coastal and inland storm tides.

Real-time, daily, and statistics of current and historical data that describe reservoir and lake levels. Reservoir data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.

Annual Water Data Reports were published annually for many decades as static archival products that supplemented direct access to current and historical water data provided by the National Water Information System (NWIS). This site helps users access historical Water Data Reports, electronic Site Data Sheets, or current on-demand, print-ready Water-Year Summaries.

The USGS StreamStats website is a GIS-based web tool for estimating streamflows at gaged and ungaged locations. Features similar to the National Streamflow Statistics program are presented to users with no programs to install. Users can visit the StreamStats website linked here and click on a stream location on the interactive map to compute estimated streamflows for floods and other statistics.

The NJTTS supplies real-time meteorological data for 120 days for flood-prone areas along the New Jersey shore and back bays to critical decision-making centers and the publically-available world wide web.
