North Fork American River: Yankee Jims Bridge to Lake Clementine

The North Fork American River, stretching from Yankee Jims Road Bridge to Lake Clementine, offers paddlers an engaging 9-mile journey through rugged terrain and lively Class II-III rapids. As you slide into the cold, rushing waters at the Colfax-Foresthill Road put-in, the river immediately sets its pace—a steady flow that both challenges and invites. This section, often called Ponderosa or Shirttail, reveals a river alive with energy, carving its way through steep canyon walls and scattered granite outcrops. The river moves decisively beneath towering pines and cedar stands, whose branches frame brief glimpses of bright blue sky.

Early in the run, the braided rapids just below Yankee Jims Road demand focused navigation, their swift currents pushing your craft deliberately toward tight eddies and rolling waves. Between flows of 800 and 1600 cubic feet per second (cfs), the rapids maintain a playful yet spirited character, perfect for those moving beyond beginner levels but not seeking constant technical strain. Higher water levels—above 1500 cfs—bring more chaotic sections, where the river asserts its power with unpredictable currents, while flows approaching 3000 cfs reveal punchy holes that call for attention and precise maneuvers.

Paddlers can choose to finish at the Ponderosa Way Bridge after about 4.5 miles or continue on for a longer run approaching 9 miles to the Upper Lake Clementine access point. The lower stretches calm somewhat, giving room to survey the river’s broadening course and impressive granite formations that catch afternoon light in warm glints. Wildlife sightings, such as occasional bobcats seen by visitors near feeder creeks, add a quiet companionship to the experience.

Spring is a particularly rewarding time here, with snowmelt swelling the river just enough to energize the rapids without overwhelming them. Winter trips are also common, though takeout access at Upper Clementine may be limited due to seasonal closures—checking current conditions is vital for trip planning.

Camping is regulated carefully along this stretch; allowable zones extend from 2000 feet downstream of Ponderosa Bridge to a mile below Codfish Creek. Securing a campfire or stove permit through Auburn State Recreation Area’s office is mandatory, ensuring a sustainable relationship with this wild river environment. Recent infrastructure improvements, such as the freshly graded takeout road near Ponderosa Bridge completed in 2024, have made access smoother and more reliable.

For paddlers seeking a balanced challenge, the North Fork American River here provides clear water that dares you forward, braided rapids that test skill and instinct, and a landscape steeped in the straightforward honesty of California’s forested canyons. Prepare with solid footwear, layered clothing for seasonal shifts, and plenty of hydration on sunny days, and you’ll find this run as rewarding for its natural pulse as for its reliable river logistics.

Paddler Safety

Stay alert to flow changes and avoid rapids above 1600 cfs unless experienced; always scout unfamiliar sections and wear proper safety equipment.

Check the USGS gauge before your trip to confirm flows are within safe and runnable levels, especially during spring runoff.
