Originally the Colorado River was named Rio Colorado (Red River) by the Spanish. It may not be immediately obvious how the river was named in such a way, especially because its color today is closer to blue-green. However, in the past the river did have a reddish-brown hue before the Glen Canyon Dam was completed in 1963. Silt and sediments gave the river its red color - now they are trapped behind the dam in the bottom of Lake Powell.
