Lake Tahoe Aquatic Invasive Species Management Plan Revision and Rapid Response Exercise

2026-11-03

TRPA is seeking proposals from qualified entities to update the existing approved Lake Tahoe Region AIS Management Plan to reflect the current status of AIS in Lake Tahoe , potential external AIS threats , and the various aspects of the Program including prevention , control , and monitoring of AIS . Proposals should include the following Tasks and describe how they will be accomplished : 1 . Convene a committee of partners to help guide the revision of the Plan and identify key stakeholders to be consulted in the revision process . a . Signatures from the Governors of California and Nevada , and the Executive Director of the Tahoe Regional Planning Agency are desired ahead of submittal to ANSTF . 2 . Update the Lake Tahoe AIS Management Plan . a . Deliverables : See “ Considerations for Proposals ” below for details on Management Plan content . b . Proposed Timeline : The timeline should note key milestones and time for draft reviews of chapters , sections , and / or appendices by the partner committee , as well as check - in points with the partner committee for sharing their review feedback . i . It is anticipated that the project will be complete in time for a submittal to ANSTF by the end of 2026 for their consideration for approval at the Spring 2027 meeting . If this schedule is not realistic , suggestions should be included in proposals . c . A detailed monitoring and response plan due to the recent discovery of golden mussels in the Sacramento - San Joaquin Delta of California . i . An assessment of monitoring tools available for golden mussel detections should be included that highlight the efficacy and limitations of various techniques . 3 . Planning and implementation of a rapid response exercise that simulates the detection of an invasive mussel species and the corresponding response by Lake Tahoe Region partners . a . Note that multiple government agencies ( in all sectors ) have authority or responsibility in the Lake Tahoe Region , and downstream , as well as non - profit entities that work collaboratively to protect the Region from a new introduction of invasive species . b . The current response plan ( Appendix F of the existing Plan ) is focused on Dreissenid species . The revision seeks to identify and incorporate any updated or missing elements of rapid response planning so it can be implemented for new detections of nonDreissenid AIS such as the golden mussel or other AIS not currently present in the Region . The revision also seeks to include relevant aspects of the National Early Detection and Rapid Response Framework and update jurisdictional authorities and contact information for partners .
