<br />) <br /> <br />6.0 SUMMARY AND RECOMMENDATIONS <br /> <br />A second winter season of cloud seeding operations was conducted over the <br />Willow Creek Drainage located in north centra] Colorado. The program was operated <br />during a two month period between February 1, 1994 and March 31. As in the fIrst <br />season, seeding was accomplished using 15 ground based silver iodide generators. There <br />were eight seeding episodes during the operational period in which the generators were <br />operated a total of 574.5 hours. <br /> <br />An evaluation of the second season of operations, based on a target-control <br />comparison of April I snowpack (water content), indicates that a possible increase of <br />approximately 25 percent occurred. This percentage is higher than anticipated and may <br />be partly due to the unusual 1993-94 winter season experienced in u""to_ r\_' Ido. <br />:sult <br /> <br />Taken toget"~- - '.' c5Yl.\W'\ ./ <br />indicated a I ~ \:-to eN .7 ..:.--- <br /> (e-b 300 J L'ta'-f.
