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.

Inverse modeling for post-wildfire hydrologic process understanding over snow-dominated watersheds Inverse modeling for post-wildfire hydrologic process understanding over snow-dominated watersheds
Wildfire-induced changes to vegetation and soil properties can alter snowpack dynamics and hydrologic processes in ways that complicate predictions of post-wildfire water availability. To better understand these effects, we coupled the Parameter ESTimation in C++ (PEST++) software with the Weather Research & Forecasting Hydrologic model (WRF-Hydro) across three burned, snow-dominated...
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...

Aquaculture Water Use
Aquaculture water use is water associated with raising organisms that live in water—such as finfish and shellfish—for food, restoration, conservation, or sport. Aquaculture production occurs under controlled feeding, sanitation, and harvesting procedures in ponds, flow-through raceways, cage and net pen culture systems, recirculating aquaculture systems, and aquaponics.
The Rusting of Arctic Rivers: Freshwater Ecosystems Respond to Rapidly Uptaking Metals
The water quality of streams and rivers in the Arctic is sensitive to rapid climate change and altered disturbance regimes.
