In Utah, in addition to the general reconnaissance of the storage facilities at the headwaters of the Sevier River and other streams, a careful survey was made of Utah Lake. This survey, run by level and transit around the lake, was for the purpose of determining the area which would be covered by damming or holding back the flood water. A description of the location and physical features of this body of water is to be found in this report under the head of Hydrography, and it will suffice to state here that after a careful study it was found that, on account of the excessive evaporation from such an enormous surface, the lake was too large to act in an economical manner as a storage reservoir. On the other hand, while it may not be advisable to hold back the water to a point above that of the average height, yet there is sufficient evidence to show that natural forces at times may raise the water level and increase the area to abnormal proportions by backing water over the great fringing marshes on the east and south. This being, therefore, the natural flood ground of the lake. land |
