Quality-assurance plan for the U.S. Geological Survey Indiana District Water-Use Program

The Indiana District Water-Use Program is an ongoing project with the primary goal of making Indiana water-use data available to Federal, State, and local water managers. The water-use data are obtained from a wide variety of sources. Some data are based on values reported by water users, and other data are based on a variety of estimation techniques. Statements of responsibility, documen- tation and data-storage requirements, sources of data, and methods of achieving project goals are included in this quality-assurance plan. (USGS)
