Greenough Park Access provides a launch point on Rattlesnake Creek, a medium-sized mountain stream in the Missoula area. The creek flows from higher elevations with a moderate gradient of 4.1 feet per mile and maintains an average flow of about 107 cubic feet per second. Water velocity averages 1.91 feet per second, making this a moving current environment suitable for paddling but requiring attention to flow conditions.
This access point serves as an entry to Rattlesnake Creek, which drains a watershed of approximately 902 square miles across western Montana. Paddlers using this site should be aware that as a medium river with consistent flow and gradient, conditions can vary seasonally with higher water during spring runoff and lower levels in summer and fall. The creek's elevation range and stream order indicate this is a legitimate whitewater and paddling resource rather than flat water.
