. . -5- Records of the diversions of these ditches are available frail 1939 to date. They shmv that in the period 1939-1941, when competitive diversions were made as between the transmountain and mead0Vl1and users, the combined mean monthly diversions of the eight ditches between the gage and McIntyre Creek amounted to about 90 second feet during periods of good streaIl flow. It is estimated that an aggregate diversion of about 70 second feet qy these ditches would constitute a reasonably adequate water supply for the lands irrigated by them. A flow of about 65: second feet at the Glendevey gage would be sufficient for such total diversion by the eight ditches. If the transmountain users should elect to make maximum possible exports from the available water supply during periods of canparatively low stream nON during the meadowland irrigation season, such as in the month of July, the run- off at the Glendeveyea3e in many of the years of a period such as 19l$-1949 would be reduced below 65 second feet. In 10 of the 35 years the flows at the gage could be diminished to amounts ranging from 9 to 20 second feet for periods varying from a week or two up to practically the entire irrigation season in a year such as 1934. The userS of meadowland ditches bet\'Teen the tunnel and McIntyre Creek have indicated that base flows in the Laramie River of 5 second feet immediately below the diversion point of the Laramie-Poudre Tunnel., and of 30 second feet at the point where the gage on the Laramie River at Glendevey is now located, for periods of a 1\Teek or ten days immediately prior to July 25, would permit sufficient diversion by those ditches to finish off the hay crops without serious loss of tonnage.
