Description: The Watershed Boundary Dataset (WBD) is a comprehensive aggregated collection of hydrologic unit data consistent with the national criteria for delineation and resolution. It defines the areal extent of surface water drainage to a point except in coastal or lake front areas where there could be multiple outlets as stated by the "Federal Standards and Procedures for the National Watershed Boundary Dataset (WBD)" “Standard” (http://pubs.usgs.gov/tm/11/a3/). Watershed boundaries are determined solely upon science-based hydrologic principles, not favoring any administrative boundaries or special projects, nor particular program or agency. This dataset represents the hydrologic unit boundaries to the 12-digit (6th level) for the entire United States. Some areas may also include additional subdivisions representing the 14- and 16-digit hydrologic unit (HU). At a minimum, the HUs are delineated at 1:24,000-scale in the conterminous United States, 1:25,000-scale in Hawaii, Pacific basin and the Caribbean, and 1:63,360-scale in Alaska, meeting the National Map Accuracy Standards (NMAS). Higher resolution boundaries are being developed where partners and data exist and will be incorporated back into the WBD. WBD data are delivered as a dataset of polygons and corresponding lines that define the boundary of the polygon. WBD polygon attributes include hydrologic unit codes (HUC), size (in the form of acres and square kilometers), name, downstream hydrologic unit code, type of watershed, non-contributing areas, and flow modifications. The HUC describes where the unit is in the country and the level of the unit. WBD line attributes contain the highest level of hydrologic unit for each boundary, line source information and flow modifications.

Copyright Text: Funding for the Watershed Boundary Dataset (WBD) was provided by the USDA-NRCS, USGS and EPA along with other federal, state and local agenciesies. Representatives from many agencies contributed a substantial amount of time and salary towards quality review and updating of the dataset in order to meet the WBD Standards. Acknowledgment of the originating agencies would be appreciated in products derived from these data. See dataset specific metadata for further information

Description: The Montana Public Land ownership layer contains most public administered lands that are at least 40 acres in size. The data was vertically integrated from the statewide Montana Cadastral layer to correspond with the public ownership records found in the original MTNHP Stewardship Data. In the present data, tribal lands have been omitted because of conflicting ownership records. These records will be added when more information becomes available. All MTNHP Stewardship attributes have been eliminated except "Owner". Conservation Easements have been removed from the layer and are now in a new Easements Feature Class found in the Montana Cadastral Data Model. Private lands found in the former Stewardship Data have been eliminated (Plum Creek, etc.). Note: The MTNHP Stewardship's land management, easement, and lease status information that were associated with the original Montana Stewardship layer were moved to separate layers by MTNHP and are available at: http://nris.mt.gov/nsdi/nris/stew_easements.html, http://nris.mt.gov/nsdi/nris/stew_leases.html http://nris.mt.gov/nsdi/nris/stew_management.html
