EX PLANATION

D Areas most favorable for irrigation development

In nwst of these areas the land surface i!J flat to gently undulating with a few isolated shallow undra~rud depressU:ms. The gTCYUnd-water reservoir underlying these areas probably has a sufficient thickness of saturated materials for develop'I'I'Wnt of moderate to large quantities of ground water Soils may be too sandy for i rrigation in areas east of Felt and south of the North Canadian River and 'Mrth of the North Canadian Ri ver between Boise City and the Okla­homa-New Mexuo Stat£ hne

D Areas less favorable for irrigation development

In SO?M places, these areas have been deeply eroded by streams, and land slopes are generally too steep for i rrigated agriculture. However, in local areas of moderate surface reltef, sprinklers possibly could be used for t rrigation The ground-water reservoir appears to have sufftctent thickness of saturated materials for developm.ent of m.oderate W large quan­tities of water. The principal waWr-bearing forma­tions are the Ogallala Formation and (or) the underlying sandstones of Cretaceous age. Northwest of Boise Ctty in Toumshtps 4 and 5 N, Ra'TI{}es 2 and 3 E., tM Purgatoire Formation and the Dakota Sand­stone, with a combined thickness of 300 feet or 11Wre, have the greatest potential for ground-water develop­ment

Areas with an unknown potential for irrigation development

Topographic conditwns generally appear favorable for irrigatwn development in most of the area. However, the water table M below the base of the Ogallala and is in the upper um.t of the Triassic rocks that do not yMld enough water for irrigation. The poWntial for developing irrigati<m supplies from the lower umt of the Triassic rocks is unknown

Areas least favorable for irrigation development In 11WSt places, these areas have been deeply eroded by

streams and slopes are generally too steep for i m ­gated ag'f"'.Culture. In areas of moderaW surface reli ejsprtnklers might be used for irrigati<m. Where water-bearing depostts have sufftctent saturated thickness and per?Mabihty, it m.ay be possible to ob­taitt moderate quantities of ground water. In some areas, the ground waWr is too high in sodium or total di ssolved solids to be sui table for irrigati<m

IRRIGATION WELL DEVELOPMENT

The number of wells has increased markedly from 26 in 1952. The most noticeable period of develop­ment began in 1963 when the number of wells in­creased from 149 ro 433 by the end of 1966, Assuming that ground-water pumpage is proportional to irriga­tion-well development, the amount of pumpage in 1966 was nearly three times that in 1963
