Real-Time Updated Flow Information

This page features real-time flow updates for the North, Middle and South Fork of the American rivers. Be sure to check the river flows before you go rafting. Bookmark this page and keep up with the latest because whitewater rafting is only exciting when there is enough water.

The North Fork American usually stops running by mid-June. The Middle and South Forks are controlled by upstream reservoir water releases. Optimal flows for whitewater rafting usually continue throughout the summer and fall months, often as late as October.

South Fork of the American (Beginner - Intermediate / Class III+):

Whitewater rafting on the South Fork is best from April through October. Consistent flows are controlled by the upstream reservoirs in the summertime with added runoff in the spring. Snow melt, precipitation, air temperature and reservoir releases can affect current river levels.

Middle Fork of the American (Beginner - Intermediate / Class III - IV):

The Middle Fork usually runs from May through October. Consistent flows for whitewater rafting are controlled by the upstream reservoirs in the summertime with added runoff in the spring. Snow melt, precipitation, air temperature and reservoir releases can affect current river levels.

North Fork of the American (Intermediate - Advanced / Class IV+):

The North Fork runs during April & May. Whitewater rafting can sometimes be enjoyed until mid-June. This river has no dams. The longevity of flows is dependent on the weather and snowpack. Snow melt, precipitation, air temperature and reservoir releases can affect current river levels. Proceed with caution when rafting at high flows.
