The Ogden Narrows river run in Utah is a Class III river run that spans approximately 5.5 miles. This section of water is best floated from early May to late June when water flows are between 1,000 and 2,000 cubic feet per second (cfs). The river features several challenging obstacles such as the "Boneyard" and "Kirkham's" rapids, where maneuvering skills are required to navigate through narrow channels and rocky outcroppings. The Ogden Narrows river run is not recommended for beginners, as the rapids and obstacles require experience and skill to navigate safely.
