This report documents the results of a study of the uses, funding, and availability of the streamflow information program in South Dakota. In 1983, 107 continuous-record surface-water gaging stations were being operated in South Dakota on a budget of $607,050. Data from most stations have multiple uses. Data uses and funding sources are identified for each station. All stations have sufficient justification for continuation although 10 are primarily used to provide data for short-term research studies. The continued operation of these 10 stations should be evaluated when the studies have been completed. (USGS)
