Intermediate quantities shall be computed by propor-
tional parts.

(3) Rio Grande at Del Norte is the recorded flow of
the Rio Grande at the U.S.G.S. gaging station near Del
Norte during the calendar year (measured above all princi-
pal points of diversion to San Luis Valley) corrected for
the operation of reservoirs constructed after 1937.

(4) Rio Grande at Lobatos less Conejos at Mouths is
the total flow of the Rio Grande at the U.S.G.S. gaging
station near Lobatos, less the discharge of Conejos River
at its Mouths, during the calendar year.

The application of these schedules shall be subject to
the provisions hereinafter set forth and appropriate adjust-
ments shall be made for (a) any change in location of
gaging stations; (b) any new or increased depletion of the
runoff above inflow index gaging stations; and (c) any
transmountain diversions into the drainage basin of the Rio
Grande above Lobatos.

In event any works are constructed after 1937 for the
purpose of delivering water into the Rio Grande from the
Closed Basin, Colorado shall not be credited with the
amount of such water delivered, unless the proportion of
sodium ions shall be less than forty-five percent of the
total positive ions in that water when the total dissolved
solids in such water exceeds three hundred fifty parts per
million.
