This is at the point where the timbers broke and the trench caved in during the campaign three years ago. Every possible advantage will be taken this season to prevent a similar occurrence. occur-rence. The recent storms have checked check-ed the drain on the reservoir so that at present the 17 foot level is being' mantained and it is hoped will prove sufficient to generate power to operate the pile driver. Should the head of water, for any reason, be insufficient in-sufficient to generate the necessary neces-sary power, a 12 horse poer gasoline engine stands in readiness readi-ness to assume the burden at a moment's notice. Of the 600,000 cubic yards of dirt that will be required to complete com-plete the dam to the 90 feet level but 200,000 cubic ft. remain to be placed, and should the companies com-panies decide to push the work to completion it could be done by May 1st! 1916. Whether or not this will be done remains to be seen. It is proposed at least to drive the piling and complete the concrete walls to the present height of the dam this summer. At present but one shift is being worked, but it is proposed to put on two shifts in the immediate imme-diate future. Salt Lake has prepared a royal entertainment for the crowds. The streets are gaily decorated; scores of bands have been provided, provid-ed, and the Fair association has arranged the greatest line of sensational sen-sational attractions possible to obtain. Uba Dam Construction (Contributed.) Work on the enlargement of the Sevier River Bridge Reservoir Reser-voir is being pushed with considerable con-siderable energy. Machinery for driving the . 40 feet steel piles is being installed as is also the over head dredging apparatus, which will operate two clam shell buckets when the moving of the dirt in the gigantic gigan-tic cut at the toe, can no longer be done to advantage by teams and scrapers. It is proposed to excavate to a depth of 20 feet on the down stream side of the dam before starting to drive the 40 foot steel piles. These piles will be driven by compressed air to bedrock and concreted together at the top where they intersect with a steel plate diaphram. On either side of the river channel and connecting with the steel piling, pil-ing, a heavily re-inforced concrete con-crete wall is being constructed from bedrock to a. point 87 feet above the natural bottom of the river. This will mean thatat some points the concrete wall will attain an extreme hight of 127 faetand will extend from bedrock bed-rock on the bottom to high water wat-er mark (when the dam is completed com-pleted the top. This wall connected as it is, and will be with the steel piling, will be impervious im-pervious to water and prevent aiy burrowing animal from djing any disastrous damage to the structure-It structure-It must be borne in mind that this concrete core will be imbedded imbed-ded in clay, sand, and paved so that but little if any of it will be be exposed. The concrete wing wall at the south east side of the dam was placed on bedrock and intersected intersect-ed the core placed a few years ago. It was plainly demonstrated demonstrat-ed that the former structure was placed on bed rock, so far, at least, as the base was exposed by the recent excavation. At present a shaft is being |
