Put In

Put In on Big Creek in Mariposa County provides access to a medium-sized river system with substantial gradient and flow. Big Creek is a 24.31-mile waterway with a total elevation drop of 392 feet, creating an average gradient of 16.1 feet per mile. The stream carries an average flow of 141.81 cubic feet per second with velocities around 1.82 feet per second, indicating moderate current conditions suitable for intermediate paddlers. The drainage area of 174 square miles supports consistent water levels throughout much of the year.

This put-in location serves as an entry point to a Class III-IV whitewater environment typical of Sierra Nevada foothills rivers. Paddlers should be prepared for the technical nature of this waterway, with the significant gradient suggesting rapids and potential obstacles. The moderate to fast water velocity and substantial flow volume demand solid paddling skills and awareness of changing conditions. Water levels and difficulty can vary seasonally, with higher flows during spring runoff and lower, potentially more technical conditions in late summer and fall.

The location in Mariposa County places this put-in in the central Sierra Nevada region, accessible from Highway 140. Paddlers should scout conditions before launching and be aware that assistance may be limited in remote mountain environments. Weather conditions can change rapidly at this elevation, and water temperature is typically cold year-round due to snowmelt sources.
