Yellowstone River Basin Available in Wyoming through StreamStats

StreamStats can provide basin delineations and basin characteristics for user-selected sites in the Yellowstone River Basin in Wyoming. This part of Wyoming was implemented as part of the effort to implement Montana. To obtain basin delineations and basin characteristics in this area of Wyoming, users should select Montana as the State. After making this selection, the map will redraw showing hatching over the entire State of Wyoming; however, the stream grid will appear at zoom level 15 or greater and delineations can be obtained.

Please refer to the State/Regional Info page for Montana for information about the streamflow statistics that can be obtained for user-selected sites. The map below shows an outline of the State of Montana in white and the implemented area (Yellowstone River Basin) in Wyoming in dark yellow.
