Results from four years of data collection will be presented showing some of the applications that have evolved from this remarkable volunteer network. A large base of users and sponsors has developed since the project first got started. Current users of the data include the National Weather Service, the U.S. Bureau of Reclamation, U.S. Department of Agriculture, U.S. Geological Survey, the Colorado Water Conservation Board, regional water conservancy districts, local utilities, farmers and ranchers, school teachers, mosquito control districts, and many more. Prospects for continuing and expanding CoCo RaHS will be discussed. The costs and work effort required to establish and maintain this type of network will also be described.
