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.

IVyTools: Space-Time Image Velocimetry for streamflow IVyTools: Space-Time Image Velocimetry for streamflow
Accurate streamflow measurements are essential for hydrologic monitoring, flood forecasting, and water resource management. Traditional in situ methods, although reliable, are often impractical or unsafe during flood conditions or at inaccessible locations. Image velocimetry techniques offer a potential non-contact alternative, yet operational adoption has been hindered by the lack of...
Predicting Minnesota lake ice phenology with deep learning, explainable methods, and a physically based benchmark, 1980-2018 Predicting Minnesota lake ice phenology with deep learning, explainable methods, and a physically based benchmark, 1980-2018
Globally, lakes are losing ice cover, but our understanding of the rates and variability of change are biased toward few lakes with long-term records. Recent works have used remote sensing and predictive modeling to supplement the observational record, but these approaches produce large errors when estimating ice phenology for individual lakes. Accurate, lake-specific estimates of ice...

Wolverine Glacier
Wolverine Glacier is located in Alaska’s Kenai Mountains, along the western flank of Prince William Sound. Glacier observations began in 1966 and continue through present as the western most USGS Benchmark Glacier.
Lemon Creek Glacier
Lemon Creek Glacier is located in southeast Alaska, at the southernmost tip of the Juneau Icefield. Glacier observations began at this site in 1953 and continue through present, serving as a central site between glaciers in the contiguous USA and those in mainland Alaska.
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.
