Show 274 INTERSTATE COMPACTS Similar gaging stations shall be maintained and operated below any other reservoir constructed after 1929, and at such other points as may be necessary for the securing of records required for the carrying out of the Compact; and automatic water stage recorders shall be main- tained and operated on each of the reservoirs mentioned, and on all others constructed after 1929. Such gaging stations shall be equipped, maintained, and operated by the Commission directly or in cooperation with an appropriate Fed- eral or State agency, and the equipment, method and frequency of measurement at such stations shall be such as to produce reliable records at all times. ARTICLE III The obligation of Colorado to deliver water in the Rio Grande at the Colorado-New Mexico State Line, measured at or near Lobatos, in each calendar year, shall be ten thousand acre feet less than the sum of those quantities set forth in the two following tabulations of rela- tionship, which correspond to the quantities at the upper index stations: Discharge of Conejos River [Quantities in Thousands of Acre Feet] Intermediate quantities shall be computed by proportional parts. 1 Conejos Index Supply is the natural flow of Conejos River at the U.S.G.S. gaging station near Mogote during the calendar year, plus the natural flow of Los Pinos River at the U.S.G.S. gaging station near Ortiz and the natural flow of San Antonio River at the UjS.GjS. gaging station at Ortiz, both during the months of April to October, inclusive. 2 Conejos River at Mouths is the combined discharge of branches of this river at the U.S.G.S. gaging stations near Los Saulees during the calendar year. Discharge of Rio Grande Exclusive of Conejos River [Quantities in Thousands of Acre Feet] Intermediate quantities shall be computed by proportional 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 principal points of diversion to San Luis Valley) corrected for the operation of reservoirs constructed after 1937. 4 Rio Grande at Lobatos less Coneios at Mouths is the total flow of the Rio Grande at the U.S.G.S. gaging stations near Lobatos, less the discharge of Conejos River at its Mouths, during the calendiar year.
