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.

Quantifying fine sediment infiltration in spawning gravel used by Chinook salmon (Oncorhynchus tshawytscha) in the Sauk River Basin, Washington, 2018–21
Fine sediment can infiltrate into river substrate that salmonid fish species (Oncorhynchus spp.) use to spawn. High levels of sediment infiltration can increase egg-to-fry mortality, which corresponds to the period when salmonids are still residing in the subsurface gravels. This study quantifies fine sediment infiltration of Chinook salmon (Oncorhynchus tshawytscha) spawning habitat during the eg
Evaluation of the lakes and impoundments drought index for the Massachusetts Drought Management Plan
The condition of surface water storage in lakes and impoundments is used as an index of drought in the Massachusetts drought management plan. The U.S. Geological Survey visited 28 of these lakes and impoundments at 14 single and multiple waterbody systems to evaluate their appropriateness for characterizing drought. The data collection and computation methods at each system were then reviewed and
Estimating groundwater level records using MOVE.1 and computing monthly percentiles from estimated groundwater records in Massachusetts
The U.S. Geological Survey, in cooperation with the Massachusetts Department of Environmental Protection, performed record extensions on groundwater levels at select wells using the Maintenance of Variance Extension type 1 (MOVE.1) method. The groundwater levels estimated from these record extensions were used to compute monthly percentiles to improve future determinations of a groundwater index.
Science
Integrated Water Prediction (IWP)
The USGS Integrated Water Prediction science program is focused on developing and improving model code, workflows, and applications of core water availability components at a national extent.
Centennial Streamgages
Centennial Streamgages are USGS streamgages that have been in operation for more than 100 years.
Water Science School
The USGS Water Science School is an educational resource provided by the U.S. Geological Survey (USGS) focused on all things water science. It offers a variety of information, and interactive activities designed to teach students, educators, and the public about various aspects of water.
