TMDL Performance Measures

Non-Urban Source Category accomplishments are tracked and reported using a set of Performance Measures (PMs) that were selected based on relevance to lake clarity, alignment with existing reporting efforts in the Tahoe Basin, and feasibility of data collection. The TMDL PMs below consist of both a subset of relevant Environmental Improvement Program (EIP) PMs, as well as other PMs specific to the needs of TMDL reporting.  

Links below provide tracking and reporting guidance, key definitions and informative context for Non-Urban Implementing Partners to accurately track and report TMDL PMs in the EIP Project Tracker. Parenthesis indicate whether the PM is an EIP PM or TMDL Program-specific.  

Atmospheric Deposition Source Category

Forest Upland Source Category

Stream Channel Erosion Source Category 


In contrast to accomplishment tracking and reporting for the Urban Uplands Source Category, TMDL PMs only quantify the extent to which activities are implemented, not the pollutant load reductions associated with these activities.
