This stretch of flume made with Armco pipe is a link in a long irrigation ditch which heads in 4 mile lake high in the cascade mountains, and runs down into the Valley around Medford, Oregon for irrigation purposes. Part of the flume is formed along the hill sides by excavating the dirt and using the earth from the ditch for a very narrow road to travel in the maintenance of this long flume. Hundreds of fishermen also travel this dike formed road to reach 4 Mile Lake which is amply stocked with trout.
