Groundwater and Streamflow Information Program
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 the potential to negatively impact streamflow, water quality, and the biological integrity in the Wood River and its tributaries. In the face of current and future stresses on the water resources in the Wood River Valley, a comprehensive assessment of the current condition of the quantity, quality, and aquatic biology of the Wood River and its major tributaries is needed as a means for the establishment of a robust, objective baseline assessment.
Science to discover and describe the location, condition, and behavior of water in the ground.
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.
