Within the U.S. Geological Survey (USGS), an extensive hydrologic network exists to record and transmit currently sensed data to the Automated Data Processing System (ADAPS; Dempster 1990). Data values are recorded at field sampling sites on electronic data-col1ection platforms (DCP). These values are transmitted by satellite to a ground station and by telecommunications lines to a USGS District office. There they are processed within ADAPS on a Prime minicomputer. Data that exceed predefined thresholds are identified as alert values. These data help alert water-resource specialists that hydrologic events are occurring. Knowledge of the current alert status at sampling sites within a State is of critical importance during floods, hurricanes, and other extreme hydrologic events. This report describes a system of computer programs designed to display current information from a hydrologic alert network.
