Modeled Stream Metabolism in Boulder Creek near Boulder, CO (2016 - 2018)

The data presented here was collected adjacent to USGS stream gage 06730200 and includes both observed and modeled values. Dissolved oxygen, dissolved carbon dioxide, stream depth, water temperature, and light intensity were collected via passive water quality sensors.

Groundwater chemistry in the Lower East Rift Zone and summit of Kilauea Volcano, Hawai'i

Chemical and isotopic analyses are reported for water samples collected from water supply wells, a geothermal well in the Puna Geothermal Venture (PGV) power plant, a hot spring in the Puna District, a research well on the summit of Kilauea Volcano, and a water catchment in the headquarters area of Hawai'i Volcanoes National Park

Groundwater Watch

Groundwater Watch displays maps, graphs, and tables describing real-time, recent, and historical groundwater data from wells and springs across the United States. Groundwater Watch groups related wells and data from active well networks and provides basic statistics about the water-level data collected by the USGS and from data supplied to us from partners through cooperative agreements.

WaterQualityWatch

WaterQualityWatch provides access to real-time water-quality data collected at more than 2,000 stream sites throughout the United States, including streamflow, water temperature, specific conductance, pH, dissolved oxygen, turbidity, and nitrate.

WaterNow

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.

WaterAlert

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.

USGS Mobile Water Data

The USGS Mobile Water Data site highlights USGS current conditions water data in a mobile-friendly website, allowing users to monitor conditions at a favorite river or stream or locate nearby monitoring locations. All USGS current conditions water data is available.

Surface Water Flow Trends in the Nation's Streams and Rivers

Changes in streamflow conditions can affect infrastructure, water supply, and ecosystems. The IWAAs Surface Water Flow Trends mapper provides access to information about long-term changes in low flows, mean flows, and peak flows. View national trends for the last 100, 75, or 50 years, or calculate trend values for a custom time period at an individual site.
