During August 2013, the Beaver Creek wildfire burned more than 114,000 acres near the south-central Idaho communities of Sun Valley, Ketchum, and Hailey. Partnering with Blaine County, the USGS installed a network of real-time precipitation gages in the burn area.

Researchers at the Columbia Environmental Research Center will use experimental streams with sand, gravel or cobble bottoms to help to determine the influence of the different substrates on hatch and initiation of dispersal of pallid sturgeon free-embryos.

Weekly sturgeon free embryo efforts were initiated on April 15, 2014 near the confluence of the Platte and Missouri Rivers.  Pictured is biologist Jeff Beasley preparing to deploy a sampling net into the Missouri River.

USGS hydrologist Greg Clark measures streamflow on Government Gulch Creek, a tributarty to the Coeur d'Alene River in northern Idaho. Streamflow data collected are included in the Coeur d'Alene Basin Environmental Monitoring Program the USGS conducts in cooperation with the Environmental Protection Agency.

On April 10, 2014 hydrologic technicians Nick Stasulis and Anthony Underwood visited the USGS gaging station on Grand Lake Stream at Grand Lake Stream, Maine. The cableway was used to make a discharge measurement with an acoustic Doppler current profiler (ADCP).

USGS scientist Vidal Mendoza measures flow downstream of the Comal Springs, Texas.

A new website now provides important information about streamflow in the Comal and San Marcos Rivers and springflow at Comal and San Marcos Springs.
