Barnegat Bay Flow and Water-quality Monitoring Activities

(scope of USGS interpertive activities to be added later)

The general objectives of the flow monitoring portion of the project are to monitor the tidally influenced flow patterns in the bay, and to quantify the volume of streamflow entering the bay from major tributaries. Stage, velocity and discharge data will be collected at key locations in the bay and watershed.

The general objectives of the water quality monitoring portion of the project are to continuously monitor several physical, chemical, and biological parameters at a site on the Barnegat Bay and on a tributary to the bay; to provide data needed for a more comprehensive assessment of water quality characteristics such as dissolved oxygen,  chlorophyll, and nitrate concentrations; to contribute to a better understanding of the spatial and temporal variability of water quality in the bay; and provide the data required for water-quality model simulation.

This monitoring program will accomplish several specific objectives: (1) to document the quantity of flow entering the bay from major tributaries, (2) to document the tidal flow in the bay and the flow entering and leaving the bay, (3) to provide information needed to develop and validate an operational circulation model of the bay, (4) to monitor water quality continuously at a strategic location on the bay, (5) to monitor water quality continuously on a major tributary to the bay.

This program is planned to continue monitoring flow for a minimum of three years and water quality for a minimum of 2 years at the identified locations.


Barnegat Bay

This project will provide NJDEP and other interested parties with a direct understanding of the flow and water quality into and through the Barnegat Bay. This understanding will be the foundation for other scientific analyses of Barnegat Bay’s hydrologic and biologic systems that may proceed contemporaneously or subsequent to this project.  The project satisfies the USGS national goals of advancing knowledge of the regional hydrologic system and providing standardized, quality-assured data to national data bases available to the public that will be used to advance the understanding of regional and temporal variations in hydrologic conditions.

An individual Scope of Work will be developed for each location identified for monitoring within this program.

General Approach

Barnegat Bay

The priority locations to be monitored under this program have been determined by the NJDEP and USGS.  The NJDEP and USGS will agree on the type of monitoring to be done at each site and the timeframes, level of effort and funding required for accomplishing the monitoring.

The USGS will collect the data in the field, review, quality assure and manage the data. Data meeting established criteria will be stored in the USGS National Water Information System (NWIS) database.
