An evaluation of the effects of different deicing salt application rates on three watersheds in Essex County, New York An evaluation of the effects of different deicing salt application rates on three watersheds in Essex County, New York
The U.S. Geological Survey, in cooperation with the New York State Department of Transportation, evaluated the effects of different deicing salt application rates on surface water, groundwater, and highway runoff quality near State highways in northern New York. Three reaches of State highways were tested with different deicing treatments between October 2019 and November 2022: a salt...
Estimating flood discharges at selected annual exceedance probabilities for unregulated, rural streams in Vermont, 2023 Estimating flood discharges at selected annual exceedance probabilities for unregulated, rural streams in Vermont, 2023
This report provides estimates of flood discharge at selected annual exceedance probabilities (AEPs) for streamgages in and adjacent to Vermont and equations for estimating flood discharges at AEPs of 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent (recurrence intervals of 2-, 5-, 10-, 25-, 50-, 100-, and 500-years, respectively) for ungaged, unregulated, rural streams in Vermont with...
User’s guide for the National Hydrography Dataset Plus High Resolution (NHDPlus HR) User’s guide for the National Hydrography Dataset Plus High Resolution (NHDPlus HR)
The National Hydrography Dataset Plus High Resolution (NHDPlus HR) is a scalable hydrologic geospatial fabric or framework, built from (1) the High Resolution (1:24,000-scale or better) National Hydrography Dataset (NHD), (2) nationally complete Watershed Boundary Dataset (WBD), and (3) 1/3-arc-second 3D Elevation Program (3DEP) digital elevation model (DEM) data (at a 10-meter ground...

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.
