Intermediate quantities shall be computed by proportional parts.

(5) The Otowi Index Supply is the recorded flow of the Rio Grande at the U.S.G.S. gaging
station at Otowi Bridge near San IIdefonso (formerly station near Buckman) during the calendar year,
exclusive of the flow during the months of July, August and September, corrected for the operation of
reservoirs constructed after 1929 in the drainage basin of the Rio Grande between Lobat05 and
Otowi Bridge.

(6) San Marcial Index Supply is the recorded flow of the Rio Grande at the gaging station
at San Marcial during the calendar year exclusive of the flow during the months of July, August and
September.

The application of this schedule shall be subject to the provisions hereinafter set forth and
appropriate adjustments shall be made for (a) any change in location of gaging stations; (b) depletion
after 1929 in New Mexico at any time of the year of the natural runoff at Otowi Bridge; (c) depletion of
the runoff during July, August and September of tributaries between Otowi Bridge and San Marcial,
by works constructed after 1937; and (d) any transmountain diversions into the Rio Grande between
Lobat05 and San Marcial.

Concurrent records shall be kept of the flow of the Rio Grande at San Marcial, near San
Acacia, and of the release from Elephant Butte Reservoir to the end that the records at these three
stations may be correlated. (Note: See Resolution of Commission printed elsewhere in this report.)
