<br />All the floodwater in Rio Hondo was intercepted and easily con-
<br />tained in the Two Rivers flood-control reservoir, constructed and
<br />maintained by the Corps of Engineers. The reservoir was empty before
<br />the storm, and it could have retained and released twice the f1oodflow
<br />of June 1965 without endangering areas downstream. The maximum
<br />storage in the reservoir was 7,400 acre. feet at 1500 hours on June 18,
<br />and the maximum release was 750 cis. The Corps of Engineers stated
<br />that controlling the flow of Rio Hondo in the Two Rivers Reservoir
<br />prevented an appreciable amount of flood damage in the Roswell area.
<br />Most of the towns in the valley are above the flood plain and there-
<br />fore had little damage. Damage in agricultural areas, whioh received
<br />the full force of the flood, was high because the flood occurred after the
<br />land was planted and when the orchard trees were in full foliage.
<br />About 3,000 acres of irrigated land was flooded, and about 300 acres of
<br />orchards was deStroyed. Owing to sediment deposition, 1,000 acres of
