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.

Interdisciplinary science approach for harmful algal blooms (HABs) and algal toxins—A strategic science vision for the U.S. Geological Survey

Executive SummaryAlgal blooms in water, soils, dusts, and the environment have captured national attention because of concerns associated with exposure to algal toxins for humans and animals. Algal blooms naturally occur in all surface-water types and are important primary producers for aquatic ecosystems. However, excessive algae growth can be associated with many harmful effects ranging from aes

Effects of episodic stream dewatering on brook trout spatial population structure

Stream dewatering is expected to become more prevalent due to climate change, and we explored the potential consequences for brook trout (Salvelinus fontinalis) within a temperate forest ecosystem in eastern North America.We estimated fish density within stream pools (n = 386) from electrofishing surveys over 10 years (2012–2021) to compare a stream that exhibits episodic dewatering (Paine Run) ag

Reservoir evolution, downstream sediment transport, downstream channel change, and synthesis of geomorphic responses of Fall Creek and Middle Fork Willamette River to water years 2012–18 streambed drawdowns at Fall Creek Lake, Oregon

Executive SummaryChapter A. IntroductionFall Creek Dam impounds Fall Creek Lake, a 10-kilometer-long reservoir in western Oregon and is operated by the U.S. Army Corps of Engineers (USACE) primarily for flood-risk management (or flood control) in late autumn through early spring months, as well as for water quality, irrigation, recreation, and habitat in late spring through early autumn. Since 201

Human-Related Compounds in Water Sources in the Grand Canyon Help Identify Water Flow Pathways and Highlight Potential Water Quality Changes

U.S. Geological Survey (USGS) scientists investigated the movement of human-generated chemicals, such as pharmaceuticals and per- and polyfluorinated substances (PFAS), in groundwater along the South Rim of the Grand Canyon. This research led to a better understanding of the movement of wastewater into groundwater, of complex underground flow patterns, and of chemicals present in springs near...

National Atmospheric Deposition Program (NADP)

The National Atmospheric Deposition Program (NADP) is a multi-partner atmospheric monitoring program that measures the concentrations and deposition of atmospheric constituents across North America. The USGS has been an NADP partner agency since 1981 and participates by providing funds for 72 National Trend Network (NTN) sites.
