About 6,200 acres of land <br />were purchased from 85 landowners. The <br />remaining 3,800 acres were Federal lands <br />from which irrigable status was withdrawn. <br />Approximately 4,600 of the irrigable acres <br />purchased were in crop production. As <br />a result of the land purchases, deep per- <br />colation was reduced by about 29,800 acre- <br />feet per year. This program was completed <br />in 1978. <br /> <br />In addition to the Title I measures described <br />, above, the Salt River Pima Maricopa Indian <br />Community Water Rights Settlement Act of <br />1988, executed in 1991, reduced WMIDD <br />irrigated lands by an additional 2,125 acres <br />and reduced WMIDD maximum con- <br />tractual consumptive use from 300,000 to <br />278,000 acre-feet per year. <br /> <br />Wellton-Mohawk Irrigation <br />Efficiency Improvement Program <br /> <br />Several entities cooperated on this program, <br />including the WMIDD and its farmers, <br />several Government agencies (Reclamation, <br />Soil Conservation Service [SCS1, and the <br />Agricultural Research Service), and the <br /> <br />University of Arizona Cooperative <br />Extension Service. Individual measures are <br />discussed in the following sections. <br /> <br />Onfann Improvements Program <br /> <br />The objective of this program was to <br />increase onfarm irrigation efficiencies by <br />improving onfarm irrigation systems and <br />management practices. SCS provided <br />design, installation, and management <br />assistance for approximately 48,000 acres of <br />land. Significant accomplishments included <br />lining 263 miles of onfarm canals; leveling <br />44,415 acres orland; making soil improve- <br />ments on more than 3,000 acres; and <br />installing 10 drip irrigation systems and <br />10,600 onfarm water-control and <br />measurelllent s~ctu,res. 'I11El f'ederal_, <br />Government contributed 75 percent of the <br />costs; farm cooperators contributed the <br />other 25 percent. <br /> <br />Irrigation Management Services Program <br /> <br />Reclamation provided technical assistance <br />through the Irrigation Management <br />Services (IMS) program, which, in turn, <br />provided onfarm, field-by-field irrigation <br />scheduling assistance. From 1977 through <br />1986, irrigation scheduling information was <br />furnished for about 49,000 acres of crops <br />each year. <br /> <br />Reclamation provided technical expertise, <br />training, and funding for the program. The <br />WMIDD provided one district employee and <br />office facilities at the district. Reclamation <br />funding for the IMS program ended in 1987. <br /> <br />Research and Demonstration Program <br /> <br />Six projects were funded under this <br />program, which provided information on <br />cultural practices, equipment, and economic <br />considerations that could lead to improved <br />irrigation efficiencies. Projects included <br />monitoring soil salinity, studying emitter <br /> <br />13 <br />
