<br />I <br /> <br />Clyde-Sherard report, and a certain log of <br />the underground by the u.S.G.S., reported in <br />Water Supply Paper No. 1378, knowing also that <br />Riverside Reservoir has almost double the cross <br />section of permeable materials under the dikes <br />that the weld County site would have and that <br />the losses through this permeable material, <br />which is 5 miles in lineal distance, are from <br />25,000 to 35,000 acre-feet of water annually, <br />knowing they can be stopped by lining the <br />reservoir with an impermeable blanket or by <br />constructing a cutoff wall around the perimeter, <br />a few calculations revealed the following con- <br />ditions must exist. Now I want to point out, <br />you see those yellow lines shown on the Weld <br />County site (again referring to the maps on <br />the wall), Riverside Reservoir is built upon <br />a shelf and if we take the entire perimeter <br />of that there is possibly double the yeilo~ <br />line under the dikes of the Riverside than <br />there is under the Weld county site. <br /> <br />(a) Very permeable gravels must exist <br />since there are no surface streams leaving <br />the reservoir embankments. <br /> <br /> (b) The rate of flow must be very high. <br /> (c) The area under and surrounding the <br />reservoir was over 5,000 acres. <br /> (d) The water gravel coefficient must <br />be close to 20",{. <br /> <br />(e) The reservoir as far as surface <br />water was a little like an iceberg, most of <br />the storage was in the underground under and <br />in the lands surrounding the reservoir. <br /> <br />I <br /> <br />(f) How to divert this water into the <br />ditch at time of need? <br /> <br />A well was drilled resulting in close to <br />six cubic feet per second discharge convenient- <br />ly blanketed off by a clay strip under the <br />ditch to prevent recirculation, proving the <br />
