As a part of the p:rellent investigat:l.on, the 1933 survey was <br />reviewed and spot checked in the field. It was concluded that results of <br />the 1933 survey would be sufficiently reliable for the present appraisal, <br />A detailed classification to current specificat:l.ons, however, probably <br />would show the lands to be somewhat less suitable for irrigation fanning. <br />Small areas, fonnerly shown as class 2, have developed seepage problems <br />and others are noticeably shallow. More detailed investigations, however, <br />should add new areas, mostly of class 3 and 4 land, which would tend to <br />offset the lands eliminated frOlll the arable classes. <br /> <br />~e 1933 survey showed an arable area of 7,800 acres, s.ll in class 2. <br />Approximately 700 acres of this land are currently being irrigated with a <br />'!he table <br /> <br />relatively reliable vater supply in the Stevens Ranch area. <br />below shows the arable lands by township and range. <br /> <br />Summary of arable lands!:! <br />(Unit--acres) <br />Location Nonirr1gs:ted <br />Township Pange land <br />34 H. 2 w. 430 <br />34t N. 2 W. 5 <br />35 N. 2 w. 2,825 <br />36 N. 2 W. 10 <br />~ N. 1 w. 30 <br />35 N. 2t w. 400 <br />36 N. ~ w. 890 <br />31 N. ~ w. 60 <br />35 N. 3 W. 110 <br />36 N. 3 w. 1,680 <br />Total 1,roO ~O <br />Y Based on 1933 reconnaissance surreys <br />land6 were classified as Clasll 2. <br /> <br />Irrigated <br />land <br /> <br />100 <br /> <br />Total <br />430 <br />5 <br />3,525 <br />10 <br />30 <br />400 <br />8go <br />60 <br />110 <br />1,680 <br />1,000 <br />1n which all <br /> <br />8 <br />
