EcoSHEDS is a collection of Spatial Hydro-Ecological Data Systems (SHEDS) designed to improve our understanding of stream ecosystems. The goal of EcoSHEDS is to provide a series of user-friendly tools for gaining insight and supporting transparent research, management, and decision-making of hydro-ecological resources.

Flow Photo Explorer

The Flow Photo Explorer is an integrated database, machine learning, and data visualization platform for monitoring streamflow and other hydrologic conditions using timelapse images.

Restoration of the Sulphur Springs Geothermal Area, Valles Caldera National Preserve: Evaluation of surface water quality and geothermal resources before, during, and after restoration

VALL recently received National Park Service (NPS) funding to restore the Sulphur Springs area to pre-mining conditions. Restoration will include removing the old buildings and debris, plugging geothermal wells and grading the mine overburden piles and other disturbed earth to a more natural angle of repose, followed by revegetation,

Water bottling across the U.S.

This Web Tool explores the count of water bottling facilities across the U.S.

Facility types include bottled water facilities, breweries, distilleries, ice facilities, soft drink manufacturing plants, and wineries.

Reported volumes withdrawn (water use) for bottled water facilities are also explored for the small number of facilities for which data are currently available. 

REmote Aquatic Chlorophyll-a Tracker (REACT)

This tool shows the presence of aquatic chlorophyll-a in select waterbodies. Note: This tool indicates the presence of aquatic chlorophyll-a and should not be used to determine if a toxic cyanobacterial bloom (harmful algal bloom) is present. 

Denitrification Only Removes Minor Amounts of Nitrate in Eastern San Joaquin Valley Groundwater

Nitrate is a major concern to water-resource managers in the eastern San Joaquin Valley, and there are extensive regulatory programs in place that seek to reduce nonpoint-source loading and eventually reduce concentrations in groundwater. 

Nothing Happens Right Away—Predicting Decreases in Nitrate Concentrations After Zero Loading is Achieved

This focuses on how we use groundwater age to predict changes in nitrate concentrations over time. Typically, deep public supply wells draw from deeper parts of the aquifer where water is decades, centuries, or even millenia old.

Irrigation Causes Naturally Occurring Uranium to Dissolve into Groundwater in the Eastern San Joaquin Valley

The USGS first identified uranium as a potential issue in California's groundwater during studies conducted in the Modesto area funded by the USGS National Water Quality Assessment Program. Subsequently, the GAMA program undertook a broader analysis of uranium concentrations across the State.

Trends in Arsenic Concentrations in the San Joaquin Valley

Arsenic is known to be a problem in groundwater used for drinking water supplies in the San Joaquin Valley. About 10% of the are of groundwater resources used for public supply contain more than the USEPA MCL of 10 µg/L. Most public-supply and domestic wells currently yield groundwater with arsenic levels below 3 µg/L and do not exhibit trends in concentration.

Albuquerque Region Nitrate Map Viewer

This interactive map summarizes historical groundwater sampling for nitrate in the Albuquerque Basin, potential sources of nitrate in groundwater, and other complementary data.
