Regular program accomplishment reporting facilitates program transparency, demonstrates accountability and helps retain support for the expenditure of public funds on water quality improvement actions. These Results pages provide a way to interactively explore TMDL implementation accomplishments. The information is organized by the urban and non-urban pollutant source categories established by the Lake Tahoe TMDL. For more information on how and why tracking and reporting varies between the urban and non-urban pollutant source categories, download the Accomplishments Tracking and Reporting Rationale.


The Lake Tahoe TMDL Performance Report is a complementary document that presents and discusses annual TMDL implementation accomplishments. The latest report version is available on the TMDL Program Management page


Urban Uplands

Results are tracked and reported as estimated annual average FSP, nitrogen and phosphorus load reductions and associated Lake Clarity Credit awards from the implementation of controls to reduce stormwater pollutant loads in the urban environment.

Forest Uplands

Results are reported using a set of relevant performance measures (PMs) that quantify the extent of activities on forestlands to control stormwater runoff from paved and unpaved roads, disturbed areas, and public facilities.

Atmospheric Deposition

Results are reported for select Environmental Improvement Project (EIP) Performance Measures (PMs) that are closley aligned with the goal of achieving load reductions in the Atmospheric Deposition Source Category.

Stream Channel Erosion

Performance Measure results are reported that quantifies the extent of stream channel restoration and enhancement activities undertaken to reduce pollutant inputs from eroding banks and beds.
