Demonstration Project

This is a DEMONSTRATION application initiated by Klamath County, Oregon, with the express purpose of applying and evaluating new and emerging technologies in an effort to share information pertaining to water supply, natural resource and social and economic issues associated with water and resources management in the Klamath Basin. The vision is a common base of information to guide discussion, debate and resolution of the complex economic, social, and resource management issues within the Basin. The development of this demonstration application is guided by a formal document which identifies various future tools and applications. Those interested in participating may contact the Klamath County Public Works Department (lhickey @ co.klamath.or.us).

Water Supply Forecast Tracking Tool (WSFTT)

Water supply forecasts are issued by the Natural Resources Conservation Service (NRCS), National Water and Climate Center. The forecasts are issued beginning in January of each year at the first of the month for the water supply season (through September). These forecasts are based upon multiple linear regression models using measured information at various locations throughout the Klamath Basin. The purpose of the WSFTT is to integrate forecast information issued by the NRCS and measured streamflow information, usually collected by the United States Geological Survey (USGS), as a qualitative assessment of the forecast information.
