• Utilize Geographic Information System (GIS) technology to develop maps <br />showing the relationship of the four aquifers. <br />Preliminary Report Conclusion Summary <br />• Accurate projections of future development would benefit from additional <br />investigation of the various sources of data and available information; <br />• Areas of hydraulic communication between the four separate aquifers is <br />indicated by the measured water level data, but additional investigation is <br />warranted to confirm the aerial extent of this hydraulic connection; and <br />• Long term management considerations should include: (1) requiring flow <br />meters or other measuring devices to be installed on all wells in the district; <br />(2) limiting acreage expansion when converting from flood irrigation to <br />sprinkler irrigation to maintain the current rate of withdrawal from the source <br />aquifer(s); (3) reducing the "allowable maximum annual amount of withdrawal <br />form 3 % acre-feet per acre to a lesser amount; (4) establish well spacing <br />criteria for specific source aquifer parameters; (5) create a funding <br />mechanism to support the district to conduct district activities; (6) create a <br />well plugging program to insure all abandoned wells are properly plugged. <br />At the District's annual meeting on January 10, 2000, the District membership voted to <br />accept the recommendations in the report and to pursue additional studies of the <br />District's ground -water resources. <br />In June 2000, the District was awarded a second grant from the Colorado Water <br />Conservation Board (CWCB) to conduct a Phase 1 level assessment of a feasibility <br />study to assess the "current" condition of the ground -water resources within the District <br />and to compare those findings with the 1967 Beck Report. McLaughlin Water <br />Engineers, Ltd., (MWE) was contracted by the District to complete the feasibility study <br />and to prepare a report of the findings. The report, entitled "Hydrology and Water <br />Resources of the Southern High Plains Designated Ground Water Basin — Phase 1 <br />Study", was published in January, 2001. <br />The principal objectives of the Phase 1 study were to: (1) develop a new conceptual <br />model of the aquifer system underlying the Basin; (2) quantify the available ground -water <br />resources in the District; and (3) define the historical and present use of ground water in <br />the District. Specific goals that were accomplished by the Phase 1 study are listed <br />below: <br />11-4 <br />99-028.003\Phase 2 Report\ SHP Introduction <br />
