Due to the volume of assistance requests and legal issues, our office can not research property title for easements, but instead refer customers to the local abstract and title companies in Lake County. We will be happy to train the public how to use the public computer in our office for research. Local administrative boundaries are maintained digitally by the Geographical Information System (G.I.S.) Department and are available upon request. A wide variety of G.I.S. data for Lake County can be downloaded from the Montana State Library Natural Resource Inventory System (NRIS).
