Looking for an Elko County Nevada Land Ownership Shapefile

Usually the BLM has a good public ownership layer since they manage the most public lands. You can try the BLM Navigator site--specifically BLM NV Surface Management Agency (SMA) Polygons .

Description: The SMA dataset was created to display the management status of the land through the BLM Administrative State of Nevada. In 2010 it was updated to be coincident with GCDB lines from Premier data. The ownership for each smallest division was identified by the previous land status layer. In areas of confusion or pieces that were divided in areas smaller then GCDB, the MTP was referenced as the final authoritative source. This project was completed 8/10/10, and is updated as necessary. Updates have not occurred to bring the dataset into alignment with the most current CadNSDI PLSS data and there are known alignment errors.
