Water is one of seven science mission areas of the U.S. Geological Survey (USGS). Water's mission is to collect and disseminate reliable, impartial, and timely information that is needed to understand the Nation's water resources.Read Science Plan
The USGS has characterized nutrient concentrations in the Klamath River and Lost River drainages over multiple years, identified spatial and temporal patterns in nutrient and organic carbon concentrations, and quantified surface water nutrient loads entering and exiting the Klamath Project.
The Mobile River Basin study is one of several NAWQA studies that began in Federal fiscal year 1997 (October 1996). Study planning and design, and analysis of existing data will be done during the first 2 years, which is consistent with all NAWQA studies. After the 2-year planning period, surface- and ground-water and biological data will be collected intensively for 3 years during a high-...
To make scientifically based water-resource decisions, elected officials, water managers, and the general public need additional information about the Wood River Valley aquifer system. A crucial part of this information is an improved understanding of the extent, thickness, and hydraulic properties of the aquifer—a hydrogeologic framework.
A component of groundwater availability is whether the water quality is suitable for a particular use. Elected officials, water managers, and the general public have raised concerns about whether water quality has been affected in developed and agricultural areas by wastewater disposal, fertilizer application, and animal waste.
Groundwater is the primary source of water supply to Ada County’s growing population. Because of a proposed development near Mayfield, the Idaho Department of Water Resources (IDWR) initiated the East Ada County Hydrologic Project to improve the scientific understanding of the groundwater resources in the area.
The endangered Bruneau hot springsnail (Pyrgulopsis bruneauensis) exists only in a geographically limited habitat of thermal springs and seeps in southwestern Idaho. As a part of its 2002 recovery plan for the springsnail, the U.S. Fish and Wildlife Service (USFWS) targeted conservation efforts to increase groundwater levels in the Bruneau area to protect the geothermal spring discharges...
Updating Low-Flow Statistics at USGS Streamgages and Regionalization of Selected Low-Flow Characteristics for Alabama Streams
As part of their mission to protect public health and aquatic ecosystems, Alabama state agencies need accurate and representative streamflow statistics to establish realistic and applicable criteria for both water quality and water quantity (fig. 1). Historically, low-flow statistics, such as the annual minimum 7-day average flow that likely will occur, on average, once every 10 years (7Q10),...
The State of Idaho needs to determine stream discharge, adjusted to remove fluctuations resulting from the operation of hydropower facilities, in the Snake River below Swan Falls Dam near Murphy, Idaho. The State will use this information to distribute water to owners of water rights in the middle Snake River, particularly at thresholds of 3,900 and 5,600 ft3/s.
Water exchange between...
Development around Coeur d'Alene Lake has accelerated over the past 25 years. Commercial and residential development adjacent to the lake plus demands for irrigation, recreation, and hydropower raise concerns about the potential for declining lake levels.
A comprehensive lake water budget helps resource managers determine the possible effects of growth on lake levels.
The mining district in the South Fork Coeur d’Alene River valley was among the Nation’s largest producers of silver, lead, zinc, and other metals from the 1880s to the 1980s. These activities have produced large quantities of waste material that contain environmentally hazardous contaminants such as cadmium, lead, and zinc. Much of this material has been discharged directly to or washed into...
Starting in 1997, the USGS began routinely studying water resources in the Clackamas River Basin. Whether it be assessing harmful algal blooms, runoff issues, streamflow, or watershed health, the USGS has worked with its partners to maintain one of Oregon's most beloved rivers.
Static flood-inundation map libraries consist of maps that have been created in advance of a flood that are ready to be served through the Internet. Each library consists of a set of flood extent and depth maps developed for predetermined stream stage intervals (for example, a map for each one foot of stage). A user can view real-time or forecast stage data from a USGS streamgage or National...

Aligning environmental management with ecosystem resilience: a First Foods example from the Confederated Tribes of the Umatilla Indian Reservation, Oregon, USA
The concept of “reciprocity” between humans and other biota arises from the creation belief of the Confederated Tribes of the Umatilla Indian Reservation (CTUIR). The concept acknowledges a moral and practical obligation for humans and biota to care for and sustain one another, and arises from human gratitude and reverence for the contributions...Quaempts, Eric J; Jones, Krista; O'Daniel, Scott J.; Beechie, Timothy J.; Poole, Geoffrey C.

Blurred lines: Multiple freshwater and marine algal toxins at the land-sea interface of San Francisco Bay, California
San Francisco Bay (SFB) is a eutrophic estuary that harbors both freshwater and marine toxigenic organisms that are responsible for harmful algal blooms. While there are few commercial fishery harvests within SFB, recreational and subsistence harvesting for shellfish is common. Coastal shellfish are monitored for domoic acid and...Peacock, Melissa B.; Gibble, Corinne M.; Senn, David B.; Cloern, James E.; Kudela, Raphael M.

Samples of stream water were...Risser, Dennis W.; Conlon, Matthew D.
A method to quantify and value floodplain sediment and nutrient retention ecosystem services
Floodplains provide critical ecosystem services to local and downstream communities by retaining floodwaters, sediments, and nutrients. The dynamic nature of floodplains is such that these areas can both accumulate sediment and nutrients through deposition, and export material downstream through erosion. Therefore, estimating floodplain sediment...Hopkins, Kristina G.; Noe, Gregory; Franco, Fabiano; Pindilli, Emily; Gordon, Stephanie; Metes, Marina J.; Claggett, Peter; Gellis, Allen; Hupp, Cliff R.; Hogan, Dianna

Jim Duda, USGS hydrologic technician, installs a Rapid-Deployment Gauge near the Elizabeth River in Norfolk, Virginia, to monitor elevated water levels caused by Hurricane Jose. An RDG is a fully functional streamgage designed to be quickly deployed for real-time data monitoring of a stream or river in emergency situations. RDGs are indispensable tools used for flood...
Borehole nuclear magnetic resonance (NMR) is an emerging geophysical method being applied to hydrogeology investigations. NMR is a quantitative geophysical method that can be used to make in situ assessments of porosity, water content, mobile and immobile water fraction, and estimates of permeability. While borehole NMR is commonly used in the oil and gas industry, it is...
Scientists from the U.S. Geological Survey and Idaho Power Company collected water, sediment, and biological samples from Brownlee Reservoir as part of an ongoing, cooperative study of mercury cycling in the Hells Canyon complex of reservoirs along the Snake River bordering Idaho and Oregon. The Idaho Department of Environmental Quality is also a partner in the study....
On September 19th, 2017 staff from the USGS NM WSC Albuquerque and Las Cruces offices visited a Climate Response Network (CRN) well just on the east side of the Organ Mountains outside of Las Cruces to receive training on integrity testing groundwater wells. What is integrity testing? Integrity testing involves adding a slug of clean water to a well and measuring how fast...
The Maine Office boat, "Miss Q", is parked next to the boat launch on Verona Island, ready to begin data collection on the Penobscot River. The crew was preparing to collect ADCP data (depth and velocity) as well as conductivity, temperature and depth profiles at various locations. In the background is the Penobscot Narrows Bridge and Fort Knox.
Along the northeast coast of Puerto Rico, USGS hydrologic technician Francisco Almanzar surveys reference elevation points to ensure the accuracy of water level data.
