Appendix A contains the sanjuan.ris file, <br /> <br />4.1.3 Base Streamflow File - sanjuan.rim <br /> <br />The sanjuan. rim file contains historical estimates from water years 1975 to 1991 of base streamflows <br />modeled within the San Juan River at the locations described in the river station file, sanjuan.ris. The <br />base streamflows shown in Table 4.1.3a represent the conditions upon which diversion, reservoir, <br />and minimum streamflow demands are superimposed, The techniques used to perform data filling or <br />extension of gaged recorded data are explained in Appendix C, Section 6. <br /> <br />This file was generated by the baseflow module of StateMod using historic streamflows, diversions, <br />EOM contents of modeled reservoirs, and estimated diversion efficiencies and return flow patterns. <br /> <br />TABLE 4.1.3A <br />Stream Flow Comparison <br />Average (acre-feet/year) 1975-1991 <br /> <br /> Base Historic <br /># ID Name Streamflow Streamflow <br />I 09339900 EF SAN JUAN R AB SAND CREEK, NR PAGOSA 69197 69197 <br />. sPGs, CO, <br />2 09341500 WEST FORK SAN JUAN RIVER NR PAGOSA 128759 127011 <br /> SPRINGS, CO, <br />3 09342000 TURKEY CREEK NEAR PAGOSA SPRINGS, CO. 33731 28728 <br />4 09342500 SAN JUAN RIVER AT PAGOSA SPRINGS, CO, 313261 301594 <br />5 09343300 RIO BLANCO BL BLANCO DIV DAM.
