Water Resources Mission Area
Water information is fundamental to national and local economic well-being, protection of life and property, and effective management of the Nation’s water resources. The USGS works with partners to monitor, assess, conduct targeted research, and deliver information on a wide range of water resources and conditions including streamflow, groundwater, water quality, and water use and availability.

U.S. Geological Survey Monitoring Milestones—Oe-151 at Woodgate, NY (433112075091501) U.S. Geological Survey Monitoring Milestones—Oe-151 at Woodgate, NY (433112075091501)
On July 9, 1926, monitoring well Oe-151 at Woodgate, New York (USGS ID 433112075091501) recorded its first groundwater data. Since then, the well has provided water data nearly continuously and has now reached a 100-year milestone for data collection. The well is part of the U.S. Geological Survey (USGS) Climate Response Network (CRN), which is a national network of wells selected to...

SPARROW modeling: Estimating nutrient, sediment, and dissolved solids transport
SPARROW (SPAtially Referenced Regression On Watershed attributes) models estimate the amount of a contaminant transported from inland watersheds to larger water bodies by linking monitoring data with information on watershed characteristics and contaminant sources. Interactive, online SPARROW mapping tools allow for easy access to explore relations between human activities, natural processes, and...
Accessing Water Use Data
The USGS provides historic and recent water use data for the United States including the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. This page provides an up-to-date guide to accessing, downloading, and using USGS water use data.
Water Use in the United States
Since 1950, the USGS has regularly produced nationwide water‑use data, creating one of the most comprehensive pictures of how water is used across the United States. Building on this rich historical record, these data give water managers a critical foundation to evaluate long‑term trends, plan strategically, and identify and quantify water availability so they can design more adaptive, resilient...
