The USGS WaterNow service lets users receive current conditions for USGS water-data-collection stations on demand via email or cell-phone text message. The user sends an email or text message containing a USGS current-conditions gaging site number, and will quickly receive a reply with the station's most recent data for one or more of its monitored parameters.

The U.S. Geological Survey WaterAlert service sends e-mail or text (SMS) messages when certain parameters, as measured by a USGS real-time data-collection station, exceed user-definable thresholds. The development and maintenance of the WaterAlert system is supported by the USGS and its partners, including numerous federal, state, and local agencies.

NWIS Current Water Data (Real-Time Data)

The USGS provides real-time or near-real-time conditions water data at sites across the Nation. Current data typically are recorded at 15- to 60-minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours, depending on the data relay technique used. Recording and transmission times may be more frequent during critical events.

National Integrated Water Availability Assessments concept map

The USGS National Integrated Water Availability Assessments concept map shows daily estimates of natural water storage (water present on the landscape) for approximately 110,000 regions across the conterminous United States. While the demonstration map is not ready for decision making, it can be used to compare an individual region’s current water storage to its historical storage.

Kentucky Drought Condition Monitor

The Ohio-Kentucky-Indiana WSC/Kentucky Agricultural Development Board choose four parameters to monitor drought: precipitation, streamflow, groundwater level, and crop moisture index. These parameters are frequently used by the Kentucky Drought Mitigation and Response Plan (2008) as indicators of the four stages of drought: drought advisory, moderate drought, severe drought, and extreme...

Videos collected for Image Velocimetry at Boneyard Creek at Urbana, IL from 2017 to 2018

The U.S. Geological Survey is testing deployments of continuous Large-Scale particle Image Velocimetry (LSPIV) streamgaging stations in areas with flashy flow regimes to measure streamflow during flood events. Videos were collected for the purpose of LSPIV streamflow analysis at a stage-discharge streamgaging station in a small, flashy urban stream in Urbana, Illinois, USA (Boneyard C

Determination of the effect of temperature (Q10) on rates of oxygen consumption in surface sediments collected from Ashumet Pond on Cape Cod, MA (2016)

This data release presents results from a laboratory study designed to measure the effect of temperature on rates of oxygen consumption within lake-bottom surface sediments at 0- to 5-cm depth. Sediment and lake water samples were collected June 8, 2016 from the South site in Ashumet Pond, Cape Cod, MA, where lake water recharges to the aquifer. Samples were shipped to Boulder, CO for l

Surface-Water Geochemistry of Mercury, Methylmercury, Nutrients, and other Constituents in Clear Lake, Lake County, California, July 2019

Clear Lake is a 180 km2 freshwater lake located in the California Coast Range, approximately 120 km northwest of Sacramento. The lake supports a wide variety of fish and bird species and is a very popular sport-fishing destination. However, fish consumption advisories associated with mercury (Hg) contamination exist for several popular recreational species. The lake is comprised of three

MODFLOW-NWT groundwater flow model used to evaluate groundwater availability with five forecast scenarios in the Northern High Plains Aquifer in Colorado, Kansas, Nebraska, South Dakota, and Wyoming

This groundwater flow model used a previously developed three-dimensional groundwater flow model
(https://doi.org/10.3133/sir20165153) was used to assess future groundwater availability in the
Northern High Plains aquifer in Colorado, Kansas, Nebraska, South Dakota, and Wyoming. In this
groundwater flow model, a modified...
