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.

| Explanation | There are no applicable performance measures, but RSWMP 2014-2025 accomplishments are related to stormwater monitoring and include: • Ongoing stormwater monitoring at at least 7 long-term monitoring sites (catchment outfalls) and up to 3 BMP effectiveness sites since October 1, 2013. A few sites have been retired due to lack of flow, and other sites have been added as replacements. • Ongoing measurement and management of continuous flow, continuous turbidity, sample event, nutrient, sediment, and meteorological data at all monitoring sites • Completion of the RSWMP Framework and Implementation Guidance (FIG) document, submitted March 31, 2015 to the State Water Resources Control Board. • Submittal and acceptance of RSWMP Quality Assurance Project Plan (QAPP), June 2015 to the State Water Resources Control Board. • Submittal and acceptance of RSWMP Annual Stormwater Monitoring Reports for water years 2014, 2015, 2016, 2017, 2018, 2019 , 2020, 2021, 2022, 2023 and 2024 to the Lahontan Regional Water Quality Control Board and the Nevada Division of Environmental Protection for permit and interlocal agreement compliance. • Ongoing Stormwater Campaign for education and outreach to agencies and public including presentations to agencies, printed ads, public service announcements, stormwater awareness posters and brochures, Tahoe RCD newsletter articles. • Completion of fully integrated RSWMP Data Management System with remote access and automated data collection, management, analysis and reporting features. • Completion of integration of RSWMP Data Management System with LT Info monitoring dashboard to present stormwater data. |
