Lake Tahoe’s fishery is among one of the least studied of all the large lakes in the world. Over time there have been a variety of stressors (e.g., introduction of species, eutrophication, nearshore habitat modification), which has altered the fishery. However, only a limited number of studies have been conducted to investigate these impacts or determine the status of a particular species. With little to no information on the status of fishery, in particular the nearshore components where most of the native littoral fish reside, scientists from the University of Nevada, Reno; Miami University in Ohio; and University of California, Davis TERC; have compiled information to determine: 1) the status of the nearshore fish community; 2) if there are quantifiable indicators and methodologies that can be created to determine the condition of the nearshore fishery; and 3) if ultraviolet radiation (UV) can be used to link nearshore and non-native fish ecology to the physical environment.

- Tahoe Science Consortium’s new Executive Director
- Invasive species in and related to issues in the Tahoe basin (Effectiveness of Aquatic Invasive Plant Control in Emerald Bay, Successful Invasive Weed Management, and Quagga Mussel Research at Lake Mead Can Inform Tahoe Science)
- Road dust control study
An integrated science plan was developed to identify and refine contemporary science information needs for the Lake Tahoe basin ecosystem. The main objectives were to describe a conceptual framework for an integrated science program, and to develop research strategies addressing key uncertainties and information gaps that challenge government agencies in the theme areas of: 1) air quality, 2) water quality, 3) soil conservation, 4) ecology and biodiversity and 5) social sciences.
Each strategy concludes with a presentation of near-term research priorities. Several factors (e.g., changing agency priorities, funding levels, and the emergence of new issues, new information, or new technologies) can affect the applicability of near-term research priorities, therefore, a science plan is considered a living document. The research priorities are reviewed and revised regularly to ensure they reflect the changing information needs and evolving priorities of agencies charged with the welfare of the Lake Tahoe basin.
