Because of an approximate I-day traveltime between the CCS WWTF and the mouth of Fountain Creek. different 24-hour periods are used at each of the gaging stations to compute daily mean discharge (fig, 3). It is evident from figure 3 that dala over a 2-day period are needed to compute the transit loss for the TRF release on a given day; however, all the required input dala are nOI available until after the 2-day period has ended, Therefore, 6 Descrtptlons or the Program Changes (1989-97) and 8 User Manual for a Tran8lt~LoS8 Accounting Program Applied 10 Fountain Creek Between Colorado Sprlnga and tha Arlran88a River, Colorado
