USGS streamgage with Satellite antenna at the edge of river.
Date Published: September 24, 2016

The USGS in Michigan-in cooperation with local, State, Tribal, and Federal partners-operates 155 streamgages recording stage and streamflow, and 13 lake-level gages. There are about 7,400 streamgages nationwide; many of these gages provide real-time data in 15-minute increments, which typically are transmitted to the World Wide Web every 1 to 2 hours using satellite, telephone, or cellular...

Date Published: September 24, 2016

Data on low-flow characteristics are used by water-resources managers for a variety of purposes, including water-supply planning, making decisions about wastewater-discharge and water withdrawal permits, and evaluating in-stream flow requirements. The Michigan low-flow network currently consists of seven sites where streamflow is typically measured only during low-flow periods. In addition to...

Date Published: September 24, 2016

The USGS operates a network of real-time water-quality monitoring stations that measure up to five physical parameters. The parameters are temperature, specific conductance, pH, dissolved oxygen, and turbidity. One to four of those parameters are measured at 26 sites, while all five parameters are measured at 13 sites. These data are used for decision making about hydroelectric power...

Lithological influences on contemporary and long-term regolith weathering at the Luquillo Critical Zone Observatory

Lithologic differences give rise to the differential weatherability of the Earth’s surface and globally variable silicate weathering fluxes, which provide an important negative feedback on climate over geologic timescales.
