The location of the power dam at Bend has finally been chosen and it will be built about 400 feet below the water wheel that stands in the river in front of the Club Houses. As announced In The Bulletin several weeks ago, the structure will be a rock fill dam. It will be made by dumping rock in the river, then overlaying these with gravel, brush, etc., followed by more rock, this again covered with gravel, until the dam will be practically water tight.
The dam will raise the water eight feet. As there is a depth now of about three feet of water at the deepest point, and as the dam will extend at least two feet above the high water line, the total height will be approximately 13 feet. It will be 300 feet long, eight feet wide on top, and will have a slope of 2 to 1 on both the up and down stream sides. This will give it a width of 60 feel on the base. A spill-way take care of the flow of the river, will lie built around the west end. The water cannot be allowed to wash over the top of this sort of a dam.
Pull particulars in regard to the construction of the power plant could not be obtained for this issue. One plan that is considered quite favorably, however, is to take out a canal from the cast end of the dam, carry the water on a high line to about the location of the present pumping plant, and there drop it on a wheel. It is possible to secure a 14 foot drop by this means. The Bulletin was also unable to learn the amount of power that will be developed, but it is understood that it is possible to generate 3,000 horsepower from the dam.
A. M. Drake will arrive in Bend from Portland the latter part of the week, and soon thereafter the work of building the dam will be taken up in earnest and pushed to an early completion. Mr. Drake, has purchased a full supply of the necessary tools and dam building paraphernalia.
Superintendent of Construction Danielson has had a force of 10 men at work during the past week. Part of them are engaged in building a bridge across the river near the site of the dam. Cribs are built on the river bank, then floated out, at the end of two strong guy ropes, to the desired location, sunk and filled with rock. These cribs will act as piers for the bridge. As the current is quite swift, the placing of the cribs is no child’s play and requires considerable muscle and no small degree of skill. It is interesting work to watch. Others of the crew are engaged in clearing the flat on the east side of the river–removing logs and general debris. From 50 to 60 men will be employed when the work is in full swing.
