] The average annual adjusted flow of the Dolores River at McPhee Dam for the period 1928-73 is
349.900 acre-feet. The Dolores River was gauged at McPhee Dam site from 1939 through 1952.
The McPhee gauge data were adjusted for the effects of Groundhog Reservoir operations and
the MVIC diversions and then correlated (one analysis for each month) with the historical flow of
the Dolores River at Dolores (1928-73) adjusted for Groundhog.
