Surface Water
The New England Water Science Center has a long history of monitoring surface-water conditions throughout New England. Continuous and discrete measurements of streamflow and water levels of lakes, reservoirs, and coastal zones provide the foundation for hydrologic assessments, hydraulic and climate-change modeling, and reporting streamflow during floods and droughts.

Algal Community Composition within the Lower Norwalk River
Harmful algal blooms (HABs), fish kills, and shellfish contamination are increasingly affecting coastal estuaries like the Norwalk River. Understanding the microscopic algae responsible for these events is essential for protecting public health, local economies, and marine ecosystems. As the environmental conditions of estuaries continue to change from nutrient enrichment, warming temperatures...
Developing Riverine and Pluvial Flood Hazard Tools for Planning and Mitigation in Massachusetts
The U.S. Geological Survey (USGS), in cooperation with the Massachusetts Executive Office of Energy and Environmental Affairs (EOEEA), is developing a web-based tool to visualize flood data in Massachusetts. Climate projections, including those derived from the Climate and Hydrologic Risk Project, are being incorporated into new and existing flood models in pilot areas distributed across the...
Assessing Sustainable Water Use in Connecticut
The U.S. Geological Survey (USGS) New England Water Science Center, in cooperation with the Connecticut Department of Energy and Environmental Protection (CT DEEP), is updating a planning-level support tool to help decision makers estimate daily mean streamflows and selected streamflow statistics to assess sustainable water use across the state of Connecticut.
New England Water Conditions Explorer
The New England Water Conditions Explorer provides interactive maps showing current surface water and groundwater conditions in the context of historical data.
Thermal Imaging to Detect Cold-Water Habitat for Atlantic Salmon and Brook Trout at Katahdin Woods and Waters National Monument
The U.S. Geological Survey (USGS), in cooperation with the National Park Service (NPS), is using airborne thermal infrared remote sensing to characterize cold-water habitat for the federally designated endangered species Atlantic salmon ( Salmo salar) and wild brook trout ( Salvelinus fontinalis) in the East Branch of the Penobscot River system within Katahdin Woods and Waters National Monument...
Statewide Studies of PFAS in Connecticut
The U.S. Geological Survey (USGS) New England Water Science Center, in cooperation with the Connecticut Department of Economic and Community Development (CT DECD) and the Connecticut Department of Energy and Environmental Protection (CT DEEP), is investigating the occurrence of per- and polyfluoroalkyl substances (PFAS) in soils and shallow groundwater across the state of Connecticut. The studies...
Coastal Water-Quality Monitoring in Massachusetts
The U.S. Geological Survey (USGS) operates high‑resolution, continuous water‑quality monitoring stations in estuaries across coastal Massachusetts to better understand these dynamic ecosystems. These efforts include collaborations with the Massachusetts Bays National Estuary Partnership (MassBays) and the Massachusetts Department of Environmental Protection (MassDEP) to support Clean Water Act...
Thermal Imagery to Inform Brook Trout Habitat Suitability and Restoration Potential, Upper Namekagon River, Wisconsin
The U.S. Geological Survey (USGS), in cooperation with the National Park Service (NPS), is using thermal infrared technology to identify cold-water habitat for brook trout and other cold-water species in the upper Namekagon River in Wisconsin. The upper Namekagon River and its tributaries have long served as a stronghold for brook trout and other cold- and cool-water species; however, changing...
Hydrologic Monitoring Branch
The Hydrologic Monitoring Branch (HMB) provides water data for all six New England states through an expansive network of monitoring locations. The HMB is responsible for a wide range of hydrologic monitoring activities, including collecting and analyzing streamflow, groundwater and coastal water levels, precipitation, and continuous water-quality information, such as water temperature and...
Applied Hydrology Branch
The Applied Hydrology Branch provides hydrologic data, research, and tools to water resource managers, stakeholders and policy makers that inform critical water management decisions throughout New England. This branch is divided into the Hydrology and Hydraulics Section, Water Quality Networks Section, Connecticut Water Quality Monitoring Section, and Massachusetts/Rhode Island Water Quality...
Hydrologic Interpretive Branch
The Hydrologic Interpretive Branch collaborates with stakeholders to design, execute, and publish scientific studies that address issues associated with water resources at local, regional, and national scales. This branch has three sections that focus on watershed and urban hydrology, integrated modeling of hydrologic systems, and the development of new statistical and geospatial tools.
Potential Effects of Reductions in Wastewater Return Flow on the Freshwater Flow System in Falmouth, Massachusetts
The U.S. Geological Survey (USGS), in cooperation with the Town of Falmouth, is simulating the potential effects of proposed changes to wastewater return flow on the freshwater system in Falmouth, Massachusetts, using an existing regional groundwater flow model.
