There is substantial reliance on <br />groundwater in the basin for irrigation <br />uses. Recreational use is an economic <br />mainstay in the headwater region, with <br />some of the best fishing and river <br />rafting in the nation. <br />Draft <br />September 2000 <br />Fountain Creek <br />Water Conservancy <br />Districts <br />Arkansas River <br />North La Junta <br />Purgatoire River <br />Southeastern Colorado <br />Upper Arkansas <br />Surface Water Diversions in Acre -feet by Use <br />Total 3,733,511 3,418,258 <br />Source: Colorado Division of Water Resources, Division 2Annual Reports <br />Growth <br />Bill Owens <br />Governor <br />Greg E.
