a. On Luning Arroyo above where it enters the Purgatoire. This station is known as "U.S.G.S. Station 07126100, Luning Arroyo near Model, Colorado." b. On Von Bremmer Arroyo above where it enters the Purgatoire. This station is know as "U.S.G.S. Station 07126200, Van Bremer Arroyo near Model, Colorado." c. On the Purgatoire near the Colorado Interstate Gas Company pumping station which is immediately below Van Bremer Arroyo. This station is know as "U.S.G.S. Station 07126300, Purgatoire River near Thatcher, Colorado." '" ",\, 1911 . Because Leitzendorfer Arroyo did not carry substantial return flows from the project and because Luning Arroyo and Van Bremer Arroyo do carry substantially all the return flows which are not measured by other gauging stations, is was determined that the three to be installed would be as follows: . These gauging stations have been in operation since 1966 and their location is appropriate for carrying out the provision of the decree. The transfer decree further instructs the Colorado State Engineer to make cer- tain flow determinations for use in assessing the administration of Trinidad Reservoir operation. Storage in Trinidad Reservoir is to be regulated in such a manner that the quantity of water occurring in the Purgatoire River at a gauge (Thatcher) below Van Bremer Arroyo shall remain the same, as determined by the State Engineer, during any ten consecutive year period as it would have had the Model Reservoir Right not been transferred. . . The State Engineer in 1983 attempted to make a determination of flows that would have been observed at the Thatcher gauge without project operation, but was unable to reach a definitive conclusion. 54 . . . . .
