Science Program Implement Programmatic Monitoring and Reporting

The objective of the Regional Stormwater Monitoring Program (RSWMP) is to determine whether urban pollutant load reductions are being achieved in response to stormwater improvement projects and management actions over time. RSWMP supports the Lake Tahoe Total Daily Maximum Load (TMDL) management system, the California National Pollutant Discharge Elimination System (NPDES) permit and Nevada Inter-local Agreement requirements, potential scientific research questions, capital improvement effectiveness evaluations, and Pollutant Load Reduction Model (PLRM) improvements. It is designed to collect and analyze high-resolution data on urban stormwater runoff in a standardized, coordinated manner.
