<br />001030 <br /> <br />;' <br /> <br />water required to satisfy their demands, A possible reason they did not have <br />adequate water in storage might be because they diverted out of priority, <br />historically. It is noted that under the simulation operating with target levels <br />set to full, these structures were not shorted because they had adequate water <br />in storage. <br /> <br />. 06-27-95 Changed proration factor into Little Bear Creek (440573) from 1.5 <br />times_USGS .gage_(02246220)..to_I. 9_times_US_G_S.gage_(Q22A.622m~rhjs <br />inflow is taken as a function of the neighboring basin based on a comparison <br />of the drainage area and inspection of the historic diversions. <br /> <br />. 06-27-95 Moved Cheyenne irrigation demand to the mainstem of the Little <br />Snake so it can take advantage of inflows from Slater Creek and the Little <br />Snake. Modified Cheyenne City inflow to 0,25 times USGS guage(09255000) <br />from 0,7 time USGS guage(09255000). Modified inflow to 540549 to 0.75 <br />times USGS guage(09255000) from 0.30 times USGS guage(09255000). <br /> <br />. 06-27-95 Modified the proration factors in the Williams Fork river as <br />follows: <br /> <br />pine creek 440611 from 0,094 0.20 <br />Morrapos Creek 440726 from 0,201 to 0.50 <br /> <br />. 06-28-95 Noticed that Coal Creek was consistantly being shorted during the <br />calibration simulation because when releases from storage were made to meet <br />targets, this water was not available to Coal Creek Ditch because it is not on <br />the mainstem below the reservoirs. Therefore the operations file was <br />modified to make target releases after the exchange to Coal Creek Ditch. <br /> <br />. 06-28-95 Output files for the historic calibration are named as follows: <br /> <br />yampa_hist.x* <br /> <br />Output files for the baseline run (reservoir targets set to full) are named as <br />follows: <br /> <br />yampa_base.x* <br /> <br />Output files for the simulation run (using consumptive crop requirements to <br />estimate head gate diversions) are named as follows: <br /> <br />yampa_simcu.x* <br /> <br />$I' <br />_ . _ .. _ .. ,_."f)J <br /> <br />Markus L Ritsch mlr@riverside,com <br />
