PRObability of Streamflow PERmanence (PROSPER)
Rivers and streams are constantly changing. Streamflows can change throughout the year and between years due to snowmelt, precipitation, diversions, and return flows. . For many streams, these fluctuations determine whether a stream has year-round flow or not.. PROSPER is a project initiated to better understand what causes these...
Blaine County’s population nearly quadrupled from about 5,700 to 22,000 people between 1970 and 2010. Residents and resource managers of the Wood River Valley of south-central Idaho are concerned about the potential effects that population growth and the expected increased demand for water might have on the quantity and quality of the valley’s ground and surface waters. Increased water use has...
These assessments will document the effects of human activities on water levels, groundwater storage, and discharge to streams and other surface-water bodies; explore climate variability impacts on the regional water budget; and evaluate the adequacy of data networks to assess impacts at a regional scale.
At the core of NSIP will be a set of USGS-funded streamgages strategically positioned across the country that are continuously operated to fulfill five Federal needs for streamflow information. These will be a permanent set of core streamgages from which streamflow information would be delivered in real time, uncompromised by changing support from funding partners.
