The results of the study, shown in tabular form and in the graph of Figure 4, provide preliminary information on the storage volume in the valley. The maximum elevation of a reservoir on the Eagle the Meadow Mountain slide to contain the .runoff of acre-feet) would be about 8030 feet. The height of a dam amount of water would be 220 feet.

A dam formed by the .Meadow Mountain slide would start at about elevation 7810 feet. At about elevation 7825, the town of Minturn would begin to flood. At elevation 7865, Minturn would be completely inundated. A dam caused by the Whiskey Creek slide would begin at about elevation 7650 feet. Flooding up the arm into Gore Creek would start at elevation 7740. Further flooding would reach Minturn at 7825 feet, completely flooding the town by elevation 7865 feet. Continued flows into the reservoir would reach West Vail at about elevation 7960 feet. The volume estimated in the Whiskey Creek. of water required to reach these threshold elevations is following table for slides at Meadow Mountain and
