The Water Suppl,y

Flaw of Rio Grande

The record of discharge of the Rio Grande at Rio Grande

City indicates the total amount of water supplied by the river at the upper end

of the Valley. (No record available for location at site of Falcon Dam, where

information is desired.) A record of flaw at Rio Grande City was produced for

period 1901-64 by combining the Rio Grande City record with records for Rio Grande

at Roma plus Rio San Juan, a tributary entering the Rio Grande between Roma and

Rio Grande City, and by correlation with' I. B. & W. C. computed record for annual

flaw into Falcon Reservoir. This record very well represents the natural flaw of

the river for period, except for relatively small amount .of water used for irri-

gat ion between Falcon Dam and Rio Grande City. The annual discharges are listed

in table 5 (p. 7) as are the 5-year and 10-year running averages. Data from

table 5 were plotted on figure 3 (p. 40) to shaw graph of annual discharges of

Rio Grande at Rio Grande City and the 10-year running averages for period 1901-64.

Also shown on figure 3 is the name and date of completion of construction of

storage dams in the basin.
