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.
Environmental Protection
Agency: The U.S. Environmental Protection Agency provides information
on watersheds across the country through their

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. Those data are now available for download.
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.
