Duncan Drive Access

Duncan Drive Access provides whitewater paddlers with entry to Rattlesnake Creek, a medium-sized river flowing through Missoula County. The creek features a moderate gradient of 4.1 feet per mile with an average flow of 106.66 cubic feet per second and velocity of 1.91 feet per second, making it suitable for intermediate paddlers seeking moving water conditions. Located near the headwaters of this 183-mile system, the access point sits at approximately 527 meters elevation, offering paddlers the opportunity to experience a relatively undeveloped stream corridor.

Rattlesnake Creek drains a substantial watershed of 902 square miles and maintains consistent flow conditions throughout most seasons. The stream's designation as a Stream Order 5 waterway indicates it has developed into a medium river with established channels and defined current patterns. Paddlers should be prepared for typical whitewater conditions associated with this gradient and flow regime, and should assess current water levels before launching as flows can vary seasonally.

Access to this site appears to be a public whitewater entry point in the Missoula area. Boaters using this access should verify current conditions, water levels, and any local use restrictions before launching. The creek's elevation profile and proximity to town make it a potentially accessible option for local paddlers seeking whitewater recreation.
