Power Generation - Big Creek Hydro
Whitewater Tied for First Reach
San Joaquin River
Fresno County, CA
The reach commonly referred to as Tied For First begins below Mammoth Pool Reservoir and ends at Mammoth Pool Powerhouse. The length of the reach is approximately 7 miles. Tied for First is class V and has many large drops which will require scouting and portaging which is difficult in this reach. Based on limited off-river flow observations, the reach is boated by advanced kayakers at flows upto 1,500 cfs. At flows between 1,500 and 2,200 cfs, the reach is boated by expert and elite kayakers only. We have no knowledge of raft runs of this reach.
