From The La Junta Tribune-Democrat (Bette McFarren) via the Ag Journal:
The Super Ditch is a plan whereby the farmer/landowner retains the land, but the water is leased by the acre-foot to an urban area for a period of one year. Whatever part of the farmer’s land which would have been watered by that portion of his irrigation rights is then fallowed (not planted) for that year. This plan makes sense particularly in dry years in which the price of the farmer’s major crop is low. By leasing a portion of his water rights, he is guaranteed an income from his land although actually growing the crop probably would not have been profitable.
