average rise in water level of 3.06 feet in 2001, as compared to 10.76 feet in <br />2000 and 1.49 feet in 1999 (Roberts, 2001). <br />5. This report estimates the proven economically recoverable ground -water <br />resources at about 12,384,700 acre-feet. At current withdrawal rates of 220,000 <br />acre-feet annually, the ground -water reserves for the entire aquifer system are <br />estimated to have an economic life expectancy of 56 years. The possible water <br />resource in the deeper, and largely unexplored Dockum, may add substantially to <br />the recoverable resource. <br />6. Ground -water recharge is primarily from precipitation, with some contribution <br />from irrigation return flows. <br />7. The District in cooperation with the State Engineer's Office added nineteen <br />production wells to the monitoring well network. These wells were measured for <br />the first time in March 2001. Identification of monitored hydrostratigraphic <br />intervals in the Basin and the overall distribution is inadequate. Several new <br />monitoring wells are needed and should include existing wells in unmonitored <br />areas and new, dedicated wells. <br />8. The District Board should consider requiring metering of all ground -water usage <br />in the District. <br />9. The District Board should require geophysical and geologic/lithologic logging of <br />any new high capacity irrigation wells drilled in the District. <br />10. The District Board should request the Colorado Ground Water Commission to <br />issue a moratorium on all new water well permits and permits for additional <br />acreage from existing wells in the District. The time period of this moratorium <br />should be determined by the Board in concert with the Commission and should <br />extend until the Commission establishes new management rules. <br />11. Drill three test holes for monitoring purposes and to obtain pump test information. <br />These newly dedicated wells should be drilled exclusively for monitoring and <br />testing ground water. <br />12. The District should enter into an information sharing relationship with the <br />adjacent Kansas ground water management districts. <br />1-2 <br />99-028.003\Phase 2 Report\SHP Summary <br />
