Abstract
An automatic water sampler was established in 2000 on the main stem of the White River at the Wyman Road Bridge. The Quality Assurance Project Plan (QAPP) was approved by EPA Region six on April 2000 and sampling was begun at that time. This station is coordinated with a USGS gauging station at the same location. This station was instrumented to collect samples at sufficient intervals across the hydrograph to accurately estimate the flux of total suspended solids, nitrogen and phosphorus into the upper end of Beaver Lake from the White River. The Upper White was designated as the states highest priority watershed in the 1999 Unified Watershed Assessment. Accurate determination of stream nutrients and sediment is critical for future determinations of TMDLs, effectiveness of best management practices and trends in water quality. The Wyman Bridge was torn down for reconstruction in early 2002. For this reason, sampling was discontinued at the end of 2001 after 21 months of sample collection. This report details the sampling and results for that period of time.
