Aligning stormwater quality datasets with priority management objectives
Nicole Beck, 2NDNATURE, LLC
Over the past decade, the Lake Tahoe Basin community (resource managers, scientific researchers, project implementers, etc.) has come together to identify and implement sustained and effective actions to reduce pollutant loads to the Lake from urban areas. There is now an opportunity to improve alignment of the stormwater data collection and analysis with the information needs of water quality improvement programs and management decision making. This research will collaborate with local agencies and regulators via the Storm Water Quality Improvement Committee (SWQIC) to develop the framework and technical guidance to achieve the following: 1) compare and interpret predicted pollutant load reductions modeled by the Pollutant Load Reduction Model (PLRM; NHC et al. 2009) to measured stormwater data, 2) integrate stormwater quality data from multiple monitoring sites to determine stormwater quality trends over time and evaluate progress towards TMDL load reduction targets, 3) inform potential stormwater tool modifications and refinements through stormwater monitoring data analyses, and 4) address additional priority management needs of future stormwater datasets. A Technical Applications Guide will be created to provide the practical details to ensure stormwater datasets can be synthesized, analyzed and reported in a standardized manner to inform critical programmatic management questions. The products will provide the necessary vision to disseminate stormwater quality obtained from a number of locations over a range of temporal intervals into formats usable by managers to make informed decisions.
Relation to Other Research Including SNPLMA Science Projects
The proposed research will inform and/or build upon a variety of programmatic, supporting tools and data collection efforts within the Tahoe Basin that extend from the Lake Tahoe Total Maximum Daily Load (TMDL), Lake Clarity Crediting Program, Tahoe Status and Trend Monitoring & Evaluation Program, and the TMDL Management System to the Pollutant Load Reduction Model (PLRM), Best Management Practices Maintenance Rapid Assessment Methodology (BMP RAM), Road RAM, and the Tahoe Regional Stormwater Monitoring Program (RSWMP). This study will also leverage research efforts supported by SNPLMA Round 9 ("Priority urban stormwater monitoring to directly inform the Pollutant Load Reduction Model (PLRM)"), Round 10 ("Tahoe stormwater particle assessment and management for urban and roadway runoff"), and Round 11 ("Quantifying the benefits of urban stormwater management").
