15 <br />1001 is outside the range of the location map-given in Exhibit 1. The <br />~ location of thug station is the t+~F 1/4, Sec.ll, T4N, R87W. The data <br />from this station is included since it is located such that it measures <br />discharge from the higher elevations of Fish Creek. As Exhibit 4 shows <br />the peak discharge for Station 1041 occurs approximately one month later <br />than the peak for Station 1003. A gaging station was installed at FI-b <br />in the fall of 1979. A sudden snow melt destroyed this station in the <br />spring of 1980 and it was abandoned. The sudden thaw had a similar <br />effect on Station FI-a and the peak discharge period was missed. Peak <br />daily discharge for Station AR-1001 for 198fl was 224 cfs and occurred on <br />May 22, 1980. Peak daily discharge for Station AR-1003 was 406 cfs and <br />oECUrred on April 23, 1980. <br />Exhibit 5 shows the seasonal hydrograph at Station FO-a. The peak <br />daily discharge measured during:. the period Qctober 1, 1979 to September <br />30, 1480. was. 76 cfs which occurred on Aprii 2~, 1980. It should be pointed <br />out that this- represents the largest. discharge measured at this location <br />since the station was installed in October. of 1975 (the previous maximum <br />was 32 cfs measured- on April ~, 19°76). <br />~ The season hydrographs as measured at Stations MI-a and MI-b are <br />presented in Exhibit 6. The peak daily discharges measured during. the <br />period October 1, 1979 to September 30, 1980 for Stations MI-a and MI-b, <br />respectively were 116 cfs on May 11, 1980 and 144 cfs on April 23, 1980. <br />In the four previous years the maximum daily discharge at Station MI-a was <br />47 cfs and occurred on May 19, 1979. The peak fpr Station MI-b occurs on <br />the same dates as the peaks at Stations FO-a and AR-1003. Again this is <br />indicative of the large snowpack in the lower elevations during the winter <br />of 1979-1980 and the sudden thaw that occurred on approximately April 23, <br />' 1980. Since a large portion of the Middle Creek Drainage Basin lies within <br />the higher elevations, the peak-daily discharge lags behind those measured <br />1 at MI-b and FO-a. <br />A comparison of daily discharges for the period April 18, 1980 to <br />June 15, 1980 at Stations FO-a, MI-a and MI-b is presented in Exhibit 7. <br />Since Station MI-b is downstream of MI-a and the confluence of Middle and <br />Foidel Creeks, the discharge at MI-b should be approximately equal to the sum <br />of the discharges at FO-a and MI-a. Although, at first glance, this does not <br /> <br />
