The greatest volume of water flowing into the Colorado River comes from the state of Utah. Specifically, the Green River, which is a major tributary of the Colorado River, contributes a significant amount of water, especially during spring runoff. Other tributaries, including those from Colorado and Wyoming, also add to the river's flow, but the Green River plays a crucial role in increasing the river's overall volume.
