Values in RED indicate basins updated since previous statewide plan.
  1. Grass/Pasture category includes any kind of grass or hay (wild, native, tame, other; excluding alfalfa), mountain meadow, and pasture.
  2. Small Grains category contains winter wheat, spring wheat, barley, and oats.
  3. Above crops aggregated for comparisons; all current basin plans did not distinguish based on identical crop types.
  4. Green River Basin Plan reported irrigated crop acreage for some of the subbasins; percent distribution for most; corn and grains acreage taken from subbasins for which they were reported; other subbasins reported no corn or grain; basin distribution was
  5. Only Northeast Wyoming, Powder/Tongue, and Snake/Salt Basin Plans reported irrigated crop acreage; other acreages calculated from crop distribution percentages from individual basin plans.
  6. 1973 Framework Plan included potatoes and other categories.
  7. No update available due to different methologies in the Agricultural use memo; WYRAG Memo 2009 only used grass/pasture and alfalfa for this updated plan.
