At this location the existing west embankment is <br /> <br /> <br />only about 4 to S feet high. The area upstream from the raised <br /> <br /> <br />embankment on the west has been left open to provide an overflow <br /> <br />area for major floods exceeding the 40-year event. This <br /> <br /> <br />emergency action has reduced the risk of dam failure but has not <br /> <br /> <br />significantly increased the level of downstream protection. A <br /> <br /> <br />severe hazard still exists from events exceeding the 40-year <br /> <br /> <br />flood. To reduce this hazard additional flood control storage, <br /> <br /> <br />such as the Upper Lowry Dam, would be required. That action, <br /> <br /> <br />however, requires authority beyond that which is currently <br /> <br />available to the Corps of Engineers and is the reason for the <br /> <br /> <br />preparation of this report. <br /> <br />. <br /> <br />30 <br />
