OOl07S change was made based upon the Upper Yampa District historic fill records. . 06-08-95 Changed the proration factors for the following base flow points: 1, Milk Creek above 440692 2, Trout Creek above 574629 To adjust for periods of negative base flow, developed proration factors using ratios to downstream gages. For 440692, the ratio of the Milk Creek gage over-the-gage.atMaybelL(O.O 15)_was.used.and.foL5JA629,_the.ratio_ofEish Creek at Milner over the gage Yampa at Hayden (0,015) was used for Trout Creek, . 06-08-95 Changed the end-of-month contents for Lake Catamount for the period March of 1978 through March of 1980. The end-of-month contents found in the database are too large by a factor of 10 for this period, . 06-09-95 Noticed low historic end-of-month contents (3 ACFf) for Elkhead reservoir for the entire year 1982, George contacted division 6 engineers (Kent Holt) for clarification of numbers, Kent said these values are wrong and should be replaced with 13,699 ACFf, . 06-09-95 Changed the historic end-of-month contents for those months when Lester Creek reservoir was full to match the physical capacity of 5675 ACFf. . 06-09-95 Changed the historic end-of-month contents for those months when Yamcolo reservoir was full to 9096 ACFf. This number matches the physical capacity as provided by both the division 6 engineer and the Upper Yampa District . 06-09-95 Changed the historic end-of-month contents for those months when Allen Basin reservoir was full to match the physical capacity of 2250 ACFf, . 06-10-95 Updated the historic target file to reflect changes made to the historic end-of-month file, . 06-10-95 Checked the baseflow computation in the Bear River above USGS station 09237500, I checked a single month, July 1989 and the results are as follows: total historic diversions(from ,ddh) = 8502 change in storage(from ,eom) = -1210 flow at gage 09237500(from ,rih) = 1371 return flow estimate = 0.75*8502 = 6376 reservoir evaporation = 44 ~
