Abstract:

An Historic Channel Modification Inventory for the years 1954, 1973 and 1999 was prepared for the upper Yellowstone River from Gardiner, Montana to Springdale, Montana in 2001 and 2002 to support the cumulative effects investigation sponsored by the Governor's Upper Yellowstone River Task Force. Channell modifications include barbs or jetties, riprap, and dikes.

Purpose:

This layer was created to support the Geomorphology Investigation sponsored by the Governor's Upper Yellowstone River Task Force.

Data Quality Information:

Attribute accuracy report:

The accuracy of the channel modification data is dependent on the photography used to capture the data: 2.0-foot pixel resolution, black and white, orthophotos at a scale of 1:15,480.

Completeness report:

Channel and floodplain modification inventory data set is complete as of the aerial photography date (October 4, 1973).

Horizontal Positional Accuracy Report:

The 1973 data sets meet the National Map Accuracy Standards for 200 feet per inch horizontal mapping.

Calendar date: 10/04/1973

Process step:

Aerial photos of the channel from Gardiner to Springdale were viewed in stereo and features identifiable as barbs or jetties, riprap, and dikes were mapped. The spatial extent of features were transferred onto a digital orthophoto mosaic of the 1973 hardcopy photos to create the ArcView shapefile.
