Show WATER DATA FOR 1916 Rxtracta from a letter sent to their entrymen by the Delta Land & Water Company. The snow fall on the Sevier River Watershed has, according to the best information at hand, exceeded that for thirty years past. Indications point to a plentiful supply of water, although an excessive amount cannot be expected on account of the extremely dry year of 1915. A great portion por-tion of the water now stored in the hills in the shape of snow will go into the ground, but nevertheless neverthe-less all indications point to ample water supply for this season. On March 1st, with the same rate of increase in the reservoir as at present, there will be about 70,000 acre feet stored, and a full reservoir reser-voir can be expected before the beginning of the season. The Sevier Bridge Reservoir will be completed this year. The dam has been increased from a thickness at the base of approximately 300 feet to approximately 750 feet. The present height of 65 feet will be increased to a little better than 90 feet. The outlet tunnel in the most part has been lined with concrete. A massive reinforced concrete gate tower has been constructed at the upper end of the tunnel and fitted with bronze faced gates. These gates supplement the old gates in the center of the dam. A huge concrete spillway is in process of construction, which will handle from 15,000 to 25,000 second feet of water. Reinforced concrete wing walls have extended from the rock on either side of the dam out to the center channel of about 300 feet. These concrete walls are joined join-ed to Lackawanna interlocking sheet steel piling, which are driven through and into the bed rock across the central portion. Joining the tops of these sheet steel piles is a copper iron diaphram,-which diaphram,-which in turn is joined to the concrete wing walls. The sheets composing this copper iron diaphram are all riveted water tight and then coated with asphalt and extend to the top of the dam. The dam i now, and will be when completed, the best and safest structure of its kind in the United States. No expense has been spared in its construction, and its equal in safety and stability cannot be found. When the dam is raised to its full height, as it will be before the flood waters come, it will im pound in the reservoir 250,000 acre feet of water. Last year there was approximately 15,000 acres of land in cultivation on the Delta Project. This acreage has been increased until about 20,000 acres will' be in cultivation during the year 1916. |
