This Yeaz's mean daily flow values for the Cottonwood and Rapid Creek flumes aze included on <br />data pages SG-23, SH-23, SI-23 and SK-9 and are presented graphically on data pages SG-24, <br />SH-24, SI-24 and SK-10. As usual, the flow in these Creeks is largely controlled by the City of <br />Palisade, depending upon their need for domestic water. Also, imgation water is diverted from <br />the creeks by private water right holders at various locations. Table 598-1 was prepared to show <br />the average monthly flows during the primary itrigation season when low flow in the creeks is <br />critical. There aze significant gaps in the collection of data from these locations. Because of the <br />changes in mine personnel, it is unknown if the data was not collected or if the data has been lost. <br />The water sampling field book shows that the locations were checked on the following dates but <br />no recorder charts could be located. Some gaps may be due to problems with the recorder or <br />flows below the minimum recording level of the recorder. Minimum recording levels of the flumes <br />are listed at the bottom of Table 598-1. <br /> SWGS-1 SWGS-2 SWGS-3 SWGS-5 <br />Date Flow (cfs) <br />5-3-97 1.41 1.90 5.08 1.33 <br />5-31-98 4.37 Flooded <br />8-2-98 0.44 0.94 1.00 0.87 <br />8-30-98 0.39 0.39 0.46 0.37 <br />9-20-98 0.44 0.39 0.35 0.30 <br />The crest stage gages installed in Coal Canyon drainage and Jerry Creek in 1996 were destroyed <br />by a storm in the summer of 1998. SWGS-06 is located downstream on Coal Canyon near the <br />proposed CRDA-3 refuse pile. SWGS-07 is upstream on Coal Canyon near the south boundary <br />line of the permit azea. SWGS-O8 is located downstream on Jerry Creek neaz our Unit Train <br />Loadout. SWGS-09 is located upstream on Jerry Creek below it's confluence with Spring Creek. <br />These monitoring locations aze shown on the Hydrologic Monitoring Location Map. The sites aze <br />monitored approximately once a month for instantaneous flow at the time of monitoring and peak <br />flow since the last time monitored. The sites were located in late 1995 but the actual gages were <br />not installed until August and September 1996 due to access problems with BLM. Access is <br />sometimes restricted by weather, BLM restricts access when the roads aze muddy. Data taken <br />during the Yeaz aze listed on data pages SR-1 for Coal Canyon and SS-1 for Jerry Creek. <br />During the upcoming yeaz, Powderhorn will be conferring with the Division to determine the <br />future of the monitoring stations in Coal and Jerry Creek. <br />AHR 98 Page 2 11/99 <br />
