Flood of July 2023 in Vermont Flood of July 2023 in Vermont
A major storm caused catastrophic flooding in many parts of Vermont on July 9–12, 2023, resulting in millions of dollars in damages. The high amount of rainfall caused several rivers to peak at record levels, in some cases exceeding records set during Tropical Storm Irene in 2011. The U.S. Geological Survey, in cooperation with the Federal Emergency Management Agency, collected and...
The Long Island Sound and Watershed Metadata map application The Long Island Sound and Watershed Metadata map application
The Long Island Sound and its watershed encompass an area of about 17,000 square miles and include the Connecticut, Housatonic, and Thames Rivers, which all drain to the sound. Dozens of organizations from government agencies, nonprofits, and Tribal Nations have developed projects and monitoring programs to analyze and protect the water resources of the watershed and sound. The abundance...
Nitrate loads and concentrations from forested watersheds and implications for Long Island Sound Nitrate loads and concentrations from forested watersheds and implications for Long Island Sound
Reduction in point sources of nitrogen has led to improvement in water quality of the Long Island Sound (LIS) since 2000, but changes in nonpoint sources are less clear. A significant yet poorly quantified nonpoint nitrogen source is the forested landscape. Because a large proportion of the LIS basin is forested, even small areal inputs from the forested landscape have a large cumulative...

Susceptibility of Water Resources to Water-Quality Impairment from Onsite Wastewater Disposal in Rhode Island
The U.S. Geological Survey (USGS), in cooperation with the Southeast New England Program (SNEP) of the U.S. Environmental Protection Agency and the Rhode Island Department of Environmental Management, is investigating the relationship between onsite wastewater treatment systems and nitrogen loads in water bodies in the Narragansett Bay watershed in Rhode Island.
Estimating Nitrogen Loading from Groundwater and Potential Effects of Sea-Level Rise in Rhode Island's Salt Ponds Region
The U.S. Geological Survey (USGS), in cooperation with the Southeast New England Program of the U.S. Environmental Protection Agency, is estimating the magnitude, spatial distribution, and travel times of nitrogen-loading to ponds and streams in the Salt Ponds region of southern Rhode Island. This information can be used to guide conservation-management efforts aimed at reducing nitrogen inputs to...
