08240500 <br />This stream flow location in the StateMod network was created to reflect historical observed <br />stream flows at USGS gage 08240500, TRINCHERA C AB TURNERS RANCH, NR FT <br />GARLAND, CO. The period of record for this gage is 1923-1998. No adjustments or data <br />filling was necessary for this location, therefore, the tstool DMI reads the historical flows <br />for this gage directly from HydroBase. <br />08241500 <br />This stream flow location in the StateMod network was created to reflect historical observed <br />stream flows at USGS gage 08241500, SANGRE DE CRISTO CREEK NEAR FORT <br />GARLAND, CO. The period of record for this gage is 1916-1998. No adjustments or data <br />filling was necessary for this location, therefore, the tstool DMI reads the historical flows <br />for this gage directly from HydroBase. <br />08242500 <br />This stream flow location in the StateMod network was created to reflect historical observed <br />stream flows at USGS gage 08242500, UTE CREEK NEAR FORT GARLAND, CO. The <br />period of record for this gage is 1923-1998. No adjustments or data filling was necessary for <br />this location, therefore, the tstool DMI reads the historical flows for this gage directly from <br />HydroBase. <br />08243500 <br />This stream flow location in the StateMod network was created to reflect historical observed <br />stream flows at USGS gage 08243500, TRINCHERA CREEK BELOW SMITH RES, NR <br />BLANCA, CO. The period of record for this gage is 1929-1998. No adjustments or data <br />filling was necessary for this location, therefore, the tstool DMI reads the historical flows <br />for this gage directly from HydroBase. <br />Table 1 <br />Statistical Measures of the Regression Results <br /> TSTooI R <br />Stream Regression Type of Correlation Comment <br />Flow Location Regression coefficiant <br />Location <br />08216500 08219500 Monthly, 0.68 to 0.93 Missing years 1950, 1983 to 1997 <br /> Lo arithmic <br />08218500 08219500 Monthly, 0.72 to 0.96 Missing years 1952 to 1954 <br /> Logarithmic <br />08223500 08219500 Monthly, 0.44 to 0.92 Missing years 1956 to 1966 and 1970 to 1997. <br /> Logarithmic Only 10 years of overlapping data, but regression <br /> created reasonable h dro ra hs. <br />08236500 08236000 Monthly, 0.14 to 0.97 Missing years 1955 to 1979.
