Computing Flow Statistics in the Barnegat Bay Watershed as a Step Toward Developing Ecological Flow Targets
Ecological flows (also referred to as environmental flows) collectively describe the components of streamflow that are needed to ensure the structure and function of a stream ecosystem. Five major components of streamflow that are important in shaping ecological processes in streams are: magnitude, frequency, duration, timing, and rate of change. The US Geological Survey, in cooperation with the...Low-Flow Characteristics
Streamflow data collection and analysis are a necessary component of effective water resource management and planning. Low-flow statistics are needed to safely allow withdrawals from and discharges to surface waters in the State of New Jersey. Operating streamflow gaging stations at every water use location would be ideal but is cost prohibitive. Statistics help extend the utility of available... - Data

Hydrologic assessment of the Edwin B. Forsythe National Wildlife Refuge
The Edwin B. Forsythe National Wildlife Refuge (hereafter Forsythe refuge or the refuge) is situated along the central New Jersey coast and provides a mixture of freshwater and saltwater habitats for numerous bird, wildlife, and plant species. Little data and information were previously available regarding the freshwater dynamics that support the refuge’s ecosystems. In cooperation with the U.S. FAuthorsChristine M. Wieben, Mary M.

The Edwin B. Forsythe National Wildlife Refuge encompasses more than 47,000 acres of New Jersey coastal habitats, including salt marshes, freshwater wetlands, tidal wetlands, barrier beaches, woodlands, and swamps. The refuge is along the Atlantic Flyway and provides breeding habitat for fish, migratory birds, and other wildlife species. The refuge area may be threatened by global climate change,AuthorsAlex R.
