Note: Blanks indicate that information was not presented in the individual basin plans.
  1. Estimates are based on outflow plus depletions from the current river basin plans.
  2. Depletion estimates are from the current river basin plans.
  3. Depleted flows are based on outflow estimates from the current river basin plans.
  4. Depletions for municipal, domestic, and stock include 14,400 acre-feet diverted to the N. Platte for City of Cheyenne use.
  5. Excludes the flows for the Little Missouri and Niobrara Rivers.
  6. The Platte River system is fully appropriated: a water right with a current-day priority cannot be expected to provide a reliable supply. Estimates exclude the flows and depletions from the Horse Creek and South Platte drainages.
  7. Drainage area is within Yellowstone National Park and includes estimates for the Madison, Gibbon, Firehole, and Gallatin Rivers.
  8. Excludes the flows for the Henrys Fork and Teton Rivers. Includes the flow of Greys River.
  9. Total Depletions not Post Compact Depletion.
