Flow is a critical variable in streams since it affects aquatic and riparian biological communities and human uses of water (i.e., recreation, public water supply, etc.). Flow regimes are changing due to anthropogenic (e.g., water withdrawals) and natural impacts (e.g., extreme weather events).

New England Tribal Engagement
The USGS New England Water Science Center (WSC) is proud to provide science support to Tribal Nations as part of our Federal Trust Responsibility to honor the government-to-government relationships that the United States has with 574 Federally-recognized Tribes. Tribal Nations have ancestral ties with the environment. Natural resources are inextricably connected to sustenance, traditional...
Integrating Streamflow and Temperature to Identify Streams with Coldwater Refugia in the Northeast
The amount of water flowing through a stream is an important driver of aquatic habitat, but scientists don’t often measure streamflow in the small stream networks that feed larger rivers. Monitoring smaller streams is especially important as climate change is causing them to (a) flood more often and more intensely, and (b) lose habitat as drought events and water temperatures increase. A...
Monitoring Merrimack River Mainstem and Tidal Reaches in Massachusetts to Evaluate Water Quality Conditions, May to September 2020
The Merrimack River watershed, the 4th largest watershed in New England (Massachusetts Executive Office of Environmental Affairs, 2001), has seen substantial growth and development in recent years.
Nutrient and Sediment Load Reduction Estimates from Intensive Street Cleaning and Leaf Litter Removal Practices in Vermont
Urban stormwater runoff contains high phosphorus concentrations that contribute to the eutrophication to receiving waters. Recent studies have further shown that leaf fall management presents an opportunity to maximize the effectiveness of common municipal practices such as street cleaning and leaf litter removal and substantially nutrient loading.
Characterization of Water Quality in the Sakonnet River, Rhode Island, 2018-19
Sections of Narragansett Bay and its eastern arm, the Sakonnet River, are considered impaired for shellfishing, aquatic habitat and recreational use by the State of Rhode Island. Aquatic habitat and water quality in the western portions of Narragansett Bay are relatively well understood, but there is comparably limited information available in the Sakonnet River. To address concerns about the lack...
