<br />a) 12,952 acre-feet of Well ton-Mohawk drainage by-passed under Minute No. 218
<br />operations by the United States, and b)1,3l9 acre-feet, less than 1% of the
<br />total deliveries, which was due principally to upstream irrigation cutbacks
<br />during and following a period of rainfall in the United States. Total flows
<br />, reaching Mexico and their sources for the past six and one-half years are

<br />The effective control on waters reaching Mexico beginning in 1967, as shm'll
<br />in the preceding table, reflects the benefits of regulation provided by the
<br />Bureau of Reclamation's Senator Hash Reservoir. The effectiveness of this
<br />control is further shown by the daily hydrographs of total deliveries to
<br />}jexico and Mexico's schedule of requests, reference E,,,hibit 4.
<br />
<br />.
