Photograph of construction work on an intake of the Colorado River, eight miles below Yuma, Arizona, [s.d.]. Two men in dark suits stand in the foreground on the left of what appears to be a large, metal cylinder which lies on a set of tracks at the top of a dirt mound on the right. At the end of the mound on the right men work on a wide, wooden cart as well as on the edge of the river at center. Piles of wood are stacked to the right of the men while towers stand across the river behind them. One tower stands on the right separate from the rest and away from the forest which blankets the far bank.
