The inventory was sponsored by the Yellowstone River Conservation Districts Council and partner agencies. The data were updated in 2013 by examination of high-resolution aerial photos taken in 2011. New features were added to the data and features that no longer exist were flagged. The source data are based on a combination of an inventory done in Park County in 1999 and an inventory that was done for the remaining downstream extent of the river in 2001. The source data were modified in 2013 to remove records of items that were outside the scope of the study. The downstream inventory was conducted in October 2001 using a Rapid Aerial Assessment (RAA) technique. Features were mapped using a helicopter and crew equipped with GPS devices. Subsequent ground-truthing (via jet boat) was conducted for purposes of locating additional structures not visible from the air and structure condition assessment. Features identified and mapped during the RAA include: - Existing stream stabilization structures (riprap, jetties, dikes, flow deflectors, etc.) - In-channel structures (irrigation diversions, head gates, pump sites) - Stream crossings (bridges, power lines) - Irrigation return flow points - Accelerated bank erosion - Significant natural sediment sources (valley wall sloughing) - Municipal Structures (water intake structures, lagoon discharge points) - Floodplain Features (dikes, elevated ditches, elevated roads) - limited mapping The Park County inventory was part of an Historic Channel Modification Inventory for the years 1954, 1973 and 1999 to support the cumulative effects investigation sponsored by the Governor's Upper Yellowstone River Task Force. Starting with a physical features inventory conducted in April, 1998 by the USDA NRCS and Montana DEQ, 1999 aerial photos of the channel from Gardiner to Springdale were viewed in stereo and a variety of adjustments were made to features identifiable as barbs or jetties, riprap, and dikes: some features were reclassified; spatial extent of features were reduced or extended as appropriate, and new features were added. Other features identified in the original inventory (photo points, irrigation diversions, etc.) were deleted. Additional information used to supplement interpretation of the 1999 photos included field notes and mapping done in August and September 2000 and 2001, and topographic mapping done in support of the project. 2011 ground condition -110.91 -103.96 47.93 44.99 ISO 19115 Topic Category inlandWaters environment structure Lower Yellowstone River Montana North Dakota Park County Sweet Grass County Stillwater County Yellowstone County Treasure County Rosebud County Custer County Prairie County Dawson County Richland County McKenzie County This is public information and may be used by organizations, agencies, units of government, or others based on needs; however they are responsible for the appropriate application.
