Colorado. Utah. New Mexico. Total. Navajo... San Juan. Piedra... Price..... Florida... Auimas.. La Plata. Mancoa... McElmo.. Acre*. 12,000 20,000 Acre*. 12,000 15,000 Acre*. 14,000 5,000 10,000 19,000 10,000 1 25,000 10,000 5,000 Acres. 38,000 25,000 15,000 20,000 23,000 10,000 25,000 Total. 111,000 12,000 34,000 157,000 1 From Dolores River. ¦ The present developed area is the result of efforts largely of individuals singly or in small groups, very few projects requiring organized effort having been executed to date. Future irrigation development.-Opportunities still exist for considerable increase in acreage by individual efforts in the headwaters region and by the extension of present irrigated areas under small Pitches in the intermediate areas between the headwaters and the San Juan River valley proper, especially from the Pine and Florida rivers. On some of the streams, notably the La Plata and to a lesser extent the Pine and Florida rivers, diversions are not difficult, but storage will be required for any major extensions while with the other Streams diversions except near the headwaters will be difficult. ' The greatest possibilities lie in diversions from the Animas and San Juan rivers whose flow has been depleted very little, but where diversions are possible only with long, expensive canal systems. The segregation of many localities into definite projects is impossible with available data and some of the listed projects are, in reality, rather a group of smaller projects. Classification of projects. Project. Class A. Class B. Class C. Class X. Navajo River___ Piedra River..... Pine or Ignacio... Florida River___ La Plata Mesas... Overland project. Turley project- Mancos River___ Total... 50,000 15,030 40,000 83,000 125,000 275,000 313,000 275,000 17,000 9,000 10,000 36,000 |
