Abstracts of the presentations given on Wednesday, 25 July 2007, in Session 14 of the UCOWR Conference.


The National Weather Service's Advanced Hydrologic Prediction Service (AHPS) currently provides river flow/stage and forecast information at more than 3,600 forecast points across the United States. Along with this information, AHPS describes potential flood impacts that may occur within the upstream and downstream influence of the forecasts points. However, similar information is not available for low flow events. In order to incorporate low flow information into the current AHPS river forecast database, the National Weather Service has undertaken pilot studies to obtain relevant low flow impact information near 83 forecast points in the Upper Mississippi, Upper Missouri, and North Platte river basins.
