Arizona has many rivers and creeks. The Colorado River is the longest and most important river in the state and forms most of the western border of the state. Others rivers include the Gila River, Salt River, and Bill Williams River. The Verde River is a National Wild and Scenic River. The Rio Grande marks the border between the United States and Mexico. Most of the small rivers in Arizona are dry in the summer. Some rivers appear dry on the surface while water continues to flow underground.
