In addition to the ground water model gages listed in Table 3, the SPDSS Ground Water <br />Contractor identified five streamflow gages on major tributaries that could provide important <br />information for the ground water modeling: <br />• Big Dry Creek at Mouth near Fort Lupton (06720990) <br />• Bijou Creek near Ft. Morgan (06759100) <br />• Bijou Creek near Wiggins (06759000) <br />• Cherry Creek at Denver (06713500) <br />• Kiowa Creek at Bennett (06758300) <br />Due to the significant amount of missing data and unique streamflow patterns at these gage <br />locations, filling techniques did not produce reasonable results and therefore these gages are not <br />included in Table 1 as key ground water model gages. Although these gages have relatively <br />short periods of record, the historical data may be useful in calibrating and checking modeling <br />results (using actual records but not with filled data). Given that the Big Dry Creek at Mouth <br />near Fort Lupton and Cherry Creek at Denver gages are still active, filling historical data may <br />become more reasonable as additional data becomes available and stronger correlations can be <br />developed. <br />Recommendations <br />Using the key streamflow gage criteria, a total of 65 gages were identified for potential surface <br />water modeling, 15 gages for ground water modeling, and 4 gages for water budget modeling. <br />The ground water and water budget modeling require key streamflow gages to have complete <br />Task2.doc 26 of 30 <br />Figure 11: South Platte River Near Weldona Filled Results <br />
