<br />WMIDD Irrigation Drainage
<br />Reduction Program
<br />
<br />This program, authorized by section 101(b)
<br />of Public Law 93-320, has reduced WMIDD
<br />irrigation drainage pumping and, thus, the
<br />required size of the YDP by removing some
<br />high-water-use lands from irrigation and by
<br />increasing irrigation efficiencies.
<br />
<br />Acreage Reduction Program
<br />
<br />Under-this program, WMIDDirrigable
<br />lands were reduced from 75,000 to
<br />65,000 acres, 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from which irrigable status was withdrawn,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 mlllrimum con-
<br />tractual consumptive use from 300,000 to
<br />278,000 acre-feet per year.

<br />Wellton-Mohawk Irrigation
<br />Efficiency Improvement Program
<br />
<br />Several entities cooperated on this program,
<br />including the WMIDD and its fanners,
<br />several Government agencies (Reclamation,
<br />Soil Conservation Service [SCSl, 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 ofland; 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 />measurement s.!rl1ctures, '!'he Federal
<br />Government contributed 75 percent of the
<br />costs; fann cooperators contributed the
<br />other 25 percent,
<br />
<br />Irrlgatlon Management Services Program
<br />
<br />Reclamation provided technical assistance
<br />through the Irrigation Management
<br />Services (IMS) program, which, in turn,
<br />provided onfann, 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
