The Speedboat monitoring site is located on the western side of Speedboat Avenue just south of Dip Street in Placer County, California. The relatively steep catchment encompasses a medium density residential neighborhood, parking lots and casinos on the California/Nevada border and is bisected by highway 28. Stormwater runoff discharges directly into Lake Tahoe through a series of culvert pipes downstream of the monitoring site.  

The Speedboat monitoring site was monitored from 2003 to 2012 by the University of California, Davis, Tahoe Environmental Research Center (UCD TERC) and the Desert Research Institute (DRI) as part of the Lake Tahoe TMDL research effort.  Data collected at this site was used to establish Event Mean Concentrations for residential land-use categories that ultimately populated the Pollutant Load Reduction Model (PLRM).  It was also used for stormwater characterization prior to and during the Brockway Erosion Control Project (ECP) that began in 2011 and was completed in 2012.

The Brockway ECP included constructing water quality structures that require little maintenance such as a new sediment basin, improved roadside swales and culvert pipes to reroute stormwater and reduce flooding and sediment transport from the old, badly eroded channels, and revegetation.  Data currently collected by the Tahoe RCD beginning in 2014 adds to the long-term data set for this catchment and may be used to assess how well the ECP was at reducing runoff volumes and pollutant loads to Lake Tahoe.
