 Some areas of the park are for experienced whitewater kayakers or canoeists only and can be dangerous. Use extreme caution in all gorge areas. Water levels and currents can change quickly downstream of TVA's powerhouse, or dam without notice. Large amounts of water may be released at any time without warning. Exit immediately if you hear warning sirens or notice changes in conditions. Always wear your PDF and check both generation and dam daily water release schedules for TVA Great Falls prior to visiting. For further information call 800-238-2264 option 4, (#36) or visit http://www.tva.gov/lakes/gfh_r.htm.
