<br />Distribution of Flow The distribution of flow at Laredo is a good estimate
<br />
<br />of the distribution into Falcon Reservoir. Distribution may be by rates of flow
<br />
<br />or by time. The diEtribution by rate of daily flow is shown in table 6 for each
<br />
<br />year and the average for period 1932-63 (period of record published by I. B. & W. C.).
<br />
<br />Data do not show a sharply defined and consistent trend, but do show that in later
<br />
<br />years more water entered the reservoir at a lower discharge rate than in former years.
