Project Summary:
The goal of this research was to develop a Tahoe Basin-wide estimate of the potential load reductions from two types of stream environment zone (SEZ) improvements: 1) improving floodplain connectivity through stream restoration of perennial systems, and 2) increasing the function of SEZs that receive direct urban stormwater to retain water and intercept pollutants before entering perennial streams.

Collectively, these estimates will provide a comparable load reduction opportunity analysis of the feasible pollutant load reductions achievable via functional stream and SEZ restoration actions in the Tahoe Basin. Basin‐wide estimates were conducted using the integration of outputs derived from a spatially explicit USGS modeling platform (SPARROW), the Pollutant Load Reduction Model (nhc et al. 2009) and the Stream Load Reduction Tool (2NDNATURE 2010).
