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.

USGS Water Data for the Nation

Current streamflow conditions map

Surface-water, groundwater, water-quality, and water-use data collected at approximately 1.9 million sites across all 50 states.

Invasive Round Goby in the Mohawk and Hudson Rivers: What’s the latest?

The Round Goby (Neogobius melanostomus) is an invasive benthic fish indigenous to the Ponto-Caspian region of Eurasia. It recently colonized the Great Lakes and has expanded eastward through the New York State Canal System over the past decade. The species was first documented in the Mohawk River watershed in 2014 and was found in the Hudson River in 2021. Round Goby can adversely affect aquatic e

Quantifying stream-loss recovery in a spring using dual-tracer injections in the Snake Creek drainage, Great Basin National Park, Nevada, USA

Simultaneous short-pulse injections of two tracers (sodium bromide [Br–] and fluorescein dye) were made in a losing reach of Snake Creek in Great Basin National Park, Nevada, USA, to evaluate the quantity of stream loss through permeable carbonates that resurfaces at a spring approximately 10 km down drainage. A revised hydrogeologic cross section for a possible flow path of the infiltrated Snake

Cienega Ranch - Semi-desert Native Grassland Restoration

At the Cienega Ranch, near Willcox, Arizona, in the foothills of the Dos Cabeza Mountains, a rancher is working to restore and conserve high- quality native grasslands and critical wildlife habitat, while keeping the land as a working cattle ranch. Our objectives were to estimate the hydrological effect of water harvesting on grassland restoration and quantify how grassland conservation efforts...
