Soil moisture datasets at five sites in the central Sierra Nevada and northern Coast Ranges, California

Soil moisture is a critical variable for understanding the impacts of drought on ecological, hydrological, and agricultural systems, as soil moisture content has a direct affect on runoff amounts. Runoff occurs as the result of precipitation (both rainfall and snowfall) that is in excess of the demands of evaporation from land surfaces, transpiration from vegetation, and infiltration into...

Ohio River at Olmsted IL

Water-quality “super” gages (also known as “sentry” gages) provide real-time, continuous measurements of the physical and chemical characteristics of stream water at or near selected U.S. Geological Survey (USGS) streamgages in Ohio, Kentucky, and Indiana. A super gage includes streamflow and water-quality instrumentation and representative stream sample collection for laboratory analysis....

Documenting Biological Recovery in Acidified Adirondack Streams in Response to the 1990 Amendment to the Clean Air Act

BACKGROUND Chemistry data from a group of Adirondack lakes monitored since the mid-1990s indicate that chemical recovery is currently underway and can be attributed to declining deposition loads of sulfate and nitrate in direct response to the 1990 amendment to the Clean Air Act (CAA) and other regulations. Changes in the water quality of several western Adirondack streams suggest that...
