With the coming of the railroads in the late 1800s, the importance of the river changed from commercial to becoming a much-needed water supply to help irrigate fields and supply drinking water. But the water levels of the Colorado River could slow to a trickle during the hot summer months and be a raging river if there was a rainy season. In the early 1900's,a massive system of dams and canals were constructed to control the flow of the river. Many lakes were formed at this time.
