Summary of 1992 and accumulated pump testing and irrigation efficiency program, 1993

This subseries contains materials collected by Robert Longenbaugh that came as part of the 2011 Longenbaugh or 2009 Colorado Water Resources Research Institute accessions but did not readily fit into existing subseries. Materials, including data, maps, correspondence, meeting minutes, and publications, pertain to groundwater and water efficiency studies conducted in the Denver Basin, South Platte Basin, High Plains, San Luis Valley, and Colorado State University, as well as several state and local committees on which Longenbaugh served. Materials are arranged alphabetically by folder title.
