<br />_ the point where many local water providers are now out of compliance with federal and <br />local drinking water requirements. <br />~ The Conduit, beginning at the South Outlet Works of Pueblo Dam and Reservoir, will <br />pass through Pueblo with the first drop off point projected to be the St. Charles Mesa <br />Water District just east of Pueblo. At that point it is expected that a filtration plant will <br />J bring the quality of the water to a point that only chlorination will be needed at the final <br />distribution points further down the Conduit. The Conduit will continue east to Fowler <br />with, a spur at Fowler to provide water for the cities and towns along Highway 96 in <br />Crowley County. The main line of the Conduit will continue east with spurs or a loop- <br />spur providing water to the entities throughout Otero County. Continuing eastward, the <br />J Conduit will provide spurs to Las Animas, Eads, May Valley, and several other small <br />towns. The conduit will terminate at the City of Lamar's water treatment plant. In total, <br />the Conduit will serve about 50,000 people in the lower Arkansas valley. A Preliminary <br />J Design of the Arkansas Valley Conduit prepared by the Applegate Group, Inc., and <br />Black and Veatch, prepared in June 2006, can be referenced for additional information <br />regarding location, cost estimates and participating entities. <br />5. Clav Creek Aquifer Recharge Program <br />j Deliveries of Fort Bent Ditch water and Fryingpan-Arkansas Project water to the Clay <br />Creek recharge area have occurred since 1973. The augmentation plan decreed in <br />Case No. W-4015 approved the use of 386 Fort Bent Ditch shares and the Project water <br />for recharge of the aquifer supporting Well Nos. 1 through 20. Since 1999, the City has <br />- operated under annually approved substitute water supply plans and Rule 14 <br />replacement plans which allowed additional recharge and well pumping above the limits <br />decreed in Case No. W-4015. Deliveries to the Clay Creek recharge area typically occur <br />- from April through October. <br />Records are available for the City's deliveries to this recharge area from water year <br />- 1996 through 2006. These records, as well as records for the amounts of Project water <br />_ used for recharge, are summarized in Appendix A Table 14. The deliveries to the Clay <br />Creek recharge area during 1996-2006 averaged 1,754 acre-feet annually and ranged <br />- from 572 acre-feet in 1999 to 2,723 acre-feet in 2006. Recharge of Project water <br />_ averaged 843 acre-feet annually. The maximum water surface area of the recharge <br />area is approximately 32 acres. With a net evaporation rate of 46.34 inches, the <br />- evaporation would not exceed 123.6 acre-feet annually if the recharge area was full all <br />_ the time. Based on the 1996-2006 operation reflected in this table, the evaporation <br />_ should not be more than about 8 percent of the delivery to the recharge area. <br />- Several water supply studies for the City were completed in the 1970s and 1980s by <br />_ Lloyd A. Hershey. An extensive hydrogeological investigation of the Clay Creek alluvium <br />was completed by Hershey, including the drilling of test holes and monitoring of ground <br />- water levels to define the characteristics and extent of the aquifer. In addition, Hershey <br />_ assessed the effectiveness of the existing recharge program and made <br />recommendations for expanding the recharge program.
