     "text": "Frequently, water withdrawals for public supply are made from the freshwater reaches of rivers and streams across new Jersey. Overall, there is a lack of scientific information describing the movement of saltwater upstream into the tributaries discharging into Delaware Bay. This project is beginning to collect water quality data along three selected tributaries in New Jersey to Delaware Bay in an effort to develop methods to relate specific conductance of the tributary waters to the upstream location of saltwater in the tributary. The location of the saltwater and freshwater interface is termed the saltfront.  Estimating the location and movement of the saltfront in these tributaries will help the scientific community understand the water quality conditions in these areas. This project is funded by the Next Generation Water Observing System (NGWOS)."

     "text": "In New Jersey, the three chosen tributaries to Delaware Bay are Maurice River, Cohansey River, and Alloway Creek. The USGS operates real-time tide gages at Bivalve, Greenwich, and Hancocks Bridge respectively. This project is leveraging the existing infrastructure where possible and expanding data collection at the tide gages to include water conductivity.  An additional telemetry gage was installed further upstream on the Maurice River in Mauricetown to increase resolution of water conductivity data for prediction of salt movement. Water temperature and water conductivity data are collected using a multiparameter sonde at the same 6-minute interval as traditional tide data. In total the project is collecting data at four key locations in New Jersey."

     "text": "Simultaneously, during selected high tides longitudinal data collection profiles are conducted to measure of water conductivity upstream of key data collection locations are being collected to document the location of the saltwater-freshwater interface (saltfront). The preliminary definition of the saltfront is being defined as the location where the vertically averaged specific conductance in the center of flow is 1100 \u00b5S/cm at 25\u00b0C. The definition of the saltfront and its relation to salinity and chloride concentration are provisional and part of this ongoing study. The location of the saltfront will be estimated by developing a relation between the daily average specific conductance at the monitoring locations and the furthest upstream location of the saltfront in the associated tributary."
