Tahoe Regional Planning Agency (TRPA): TRPA has the Plan Area Statement and El Dorado County Parcel Data as GIS coverages online.
Western Regional Climate Centers: The Western Regional Climate Center has data on precipitation and precipitation frequency for the western United States.
National Gap Analysis Program: The Gap Analysis Program for California has collected a raster dataset of landuse. Unfortunately, the dataset is in an Albers projection and won't overlay with the rest of the data on the Lake Tahoe Data Clearinghouse. A regional dataset available as ArcInfo Export files and Metadata can be downloaded at http://www.biogeog.ucsb.edu/projects/gap/gap_data_reg.html.
Lake Tahoe Basin Riparian Assessment: The U.S. Forest Service Lake Tahoe Basin Management Unit and researchers at the University of Nevada at Reno recently completed an assessment of channel conditions and wildlife habitat in the riparian corridors of 15 river-side areas in the Lake Tahoe Basin. This study was funded in part by the California Tahoe Conservancy. The study produced several sets of geographic data for each of the riparian corridors. The data have been moved and are not currently available for download. Future availability is TBD.
Northwestern Nevada Real-time Streamflow streamflow data are available for Walker Lake Basin, Carson River Basin, Lake Tahoe Basin and Pyramid Lake Basin.
Tahoe Basin Existing Vegetation Map consists of a raster classification map (at a species level of thematic resolution) and an associated GIS vector coverage containing a suite of derived vegetation classification and structural attributes. This is a vector map derived from image analysis of IKONOS satellite imagery, and funded by both TRPA and the Forest Service.
