Lake Tahoe Clarity Model

At the request of its Bi-State Executive Committee, the Tahoe Science Advisory Council (TSAC) was requested to prepare a Report on the status of Lake Tahoe Clarity model (LCM) including:

1)    The identification of the strengths and deficiencies of the existing Lake Clarity components/sub models.
2)    A summary of the availability of model inputs (data sources) – e.g. meteorology, water inflows, loads, distributed load sources, remote sensing, and in-lake data, including optical conditions, temperature, chemistry, currents, particles, phytoplankton.
3)    The valuation of existing or recommended linkages to external models and reporting mechanisms.
4)    Recommendations for next steps.


While the LCM was originally developed to address clarity questions at Lake Tahoe as part of the Tahoe TMDL, the model (or versions of it) has been utilized to address other questions at Lake Tahoe and other lakes in California and Nevada. In preparing this report the sub-committee chose to view the model, and any successors to it, as being a tool that has the potential to address a range of current and emerging issues at Lake Tahoe that extend beyond pelagic clarity, while recognizing that pelagic clarity will remain a management focus.
