Some Quick Facts

  • Landscape mosaic of bottomlands and uplands includes every major life zone in North America from Upper Sonoran (cold desert) through alpine tundra.
  • Wildlife includes threatened and endangered species like Rio Grande Cutthroat Trout and the Western Willow Flycatcher. This biodiversity is supported and extended by the acequia system.
  • It's documented that there are more than 400 native plants and more than 400 native animals including visiting yellow-throated warblers and resident flycatchers. ‘We grow ecosystems’.
  • 23k acres acequia irrigated row, field, orchard crops.
  • 350 small farmers with adjudicated water rights on 76 acequias.
  • Water rights pertain to historic use rights by heirs and successors to the ‘restored’ common lands of the 80,000-acre La Sierra Commons.


  • What does Acequia mean? it comes from the Arabic, as-Saquiya, the water bearer or the one who carries the water; also: the barmaid.
  • The acequia is a snow-melt dependent, gravity-driven, community irrigation ditch system managed by local farmers who hold use rights and do not “own” the water itself. These use rights holders are known as parciantes.
  • First acequia in Colorado, San Luis Peoples Ditch (1852); 35 acequias by 1861.

Acequia facts

  • 1861-76: Colorado Territorial Legislature recognized acequia institutions and law. Attempts have been made to remove this law so that commercialization of water use could be established. April 2009: HB 09-1233 -Colorado Acequia Recognition Law signed by Gov. Ritter.
  • The allotment of water (repartimiento) on the acequia is managed by a mayordomo (ditch rider or ditch boss) elected on the basis of one irrigator/one vote.
  • The acequia system produces significant economic-base services and cultural ecological benefits

Redefining Water Rights

HB 1233-09. The Colorado statute declares that acequia institutions are among the oldest forms of local self-governance in the Western U.S and that community ditches represent a much older alternative of law to the doctrine of prior appropriation. It declares and that acequia customary norms emphasize equity and fairness and not just priority in the allocation of water rights.

The law also established that acequias and their farming communities are worthy of protection and preservation.
