The river is subject to seasonal trends, with peak flows occurring in the spring due to snowmelt. There are no major dams on the Rio Grande at Wagon Wheel Gap, but there are several small diversion structures for irrigation purposes. Interestingly, the Rio Grande is the fifth-longest river in North America, and it flows from Colorado to the Gulf of Mexico.
