Paddle this 9.5-mile stretch from the Middle Fork confluence to Folsom Lake for a blend of natural energy and engineered rapids, where every current challenges your skills and reward the prepared adventurer."

North Fork American River: From Confluence to Folsom Lake

The North Fork American River, flowing boldly from its confluence with the Middle Fork to the expansive Folsom Lake, offers paddlers a compelling mix of steady Class II(III) rapids and striking scenery shaped by both nature and human history. This 9.5-mile stretch unfolds through a rugged canyon carved by persistent waters, with each wave and current inviting you to engage directly with the river’s restless energy.

Starting at the confluence, where the Middle and North Forks meet, paddlers can feel the dynamics of the waters merging—the river pulses with renewed force, daring kayakers and rafters to test their skills. The landscape here is a blend of sheer granite walls and forested slopes, the air filled with the sharp scent of pine and the sound of rushing water guiding you downstream.

A significant highlight is the Pumping Station Rapids, an engineered marvel born from Auburn’s need for city water supply. Here, the river splits around a pumping station, creating two channels that ripple with artificial yet thrilling rapid features. The waves and hydraulics shift with river levels, sometimes forming playful surf spots that beg for a ride. Though public vehicle access is currently limited, the area’s raw, shifting water challenges paddlers to read the river and find the best lines.

The take-out options reflect the river’s varied terrain and access logistics. Birdsall take-out, just below the Pump Station, provides the easiest and most direct exit point with parking perched above the river. In contrast, Oregon Bar offers wrap-around access to a final cluster of minor rapids but demands a strenuous carry from a distant parking area, making it a test of endurance after paddling. For those willing to extend their journey, paddling across the Folsom Reservoir to Rattlesnake Bar boat ramp is a peaceful finish that trades the bump and churn of rapids for wide, reflective water.

Understanding river flow is crucial here. At flows around 1000-1400 cfs, the rapids reveal their balanced, challenging forms—waves craftable for play boating, holes that test maneuvering, and an overall pulse that pushes you efficiently downstream. Lower flows expose hazards like submerged debris near the Highway 49 Bridge, demanding caution and alert navigation. High flows transform rapids into powerful hydraulics that can be both awe-inspiring and unforgiving, notably at the Pumping Station and near the Auburn Dam site.

Access is straightforward but requires preparation. Most paddlers use the confluence as their put-in, reached by driving east on I-80 and south on Highway 49, turning onto Old Foresthill Road to find well-marked parking areas along the river. Take-out decisions depend on your stiffness to carry boats or your appetite for a reservoir paddle-out.

From a practical standpoint, expect rocky, gravelly riverbeds punctuated with swift current and waves shaped by both natural flow and human modification. Footwear with good grip is important for all access points, especially at take-outs with significant carry. Hydration and timing your trip to avoid extreme flows will maximize safety and enjoyability. Early spring through late fall offers the best windows, with the river’s character evolving as seasonal water releases and rainfall ebb and swell.

This section calls for respectful engagement with a river that reveals its personality differently at each flow level. It challenges paddlers not just physically, but mentally—requiring sharp observation, fluid adaptability, and a readiness to embrace both calm passages and sudden surges. The echoes of Auburn’s dam legacy linger, but so does the river’s undiminished spirit, inviting you to carve your own path through its waters.

Whether you’re carving waves at the Pumping Station, lining up eddies below cherry-picked rapids, or drifting across Folsom’s glassy expanse, the North Fork American River’s stretch from confluence to lake offers an adventure that respects its history and rewards careful planning with memorable whitewater paddling.

Paddler Safety

Always scout unfamiliar rapids, especially near engineered sections and at low flows watch for submerged obstacles. Carry required safety gear and plan for logistics at take-outs with difficult access.

River Sections

Confluence Put-in

II
StartConfluence of Middle and North Fork American River
EndPumping Station Rapids
Length3.6 miles

Begin at the river’s confluence where calm flows merge and quickly ramp up to a series of moderate rapids. The water here tests basic maneuvers amidst changing currents, with access trails nearby and river views framed by forested slopes.

Note: Be cautious of submerged metal near Highway 49 Bridge at low flows.

Pumping Station Rapids

II+
StartPumping Station
EndBirdsall Take-Out
Length0.1 miles

An engineered rapid section where the river splits and flows around a city water pump station. Offers play boating potential with varying wave sizes depending on flow. Public vehicular access currently limited.

Note: Portage trail available on river left for scouting or exit; no direct vehicle parking at river level.

Birdsall to Oregon Bar

II
StartBirdsall Take-Out
EndOregon Bar Take-Out
Length1.6 miles

This stretch continues with smaller rapids and eddies, requiring steady paddling skill and situational awareness. Oregon Bar challenging for take-out due to steep terrain and long carry; consider reservoir paddle-out as an alternative.

Note: Oregon Bar take-out demands boat carry uphill; plan accordingly.

Oregon Bar to Rattlesnake Bar

Class I
StartOregon Bar Take-Out
EndRattlesnake Bar Boat Ramp
Length3.9 miles

Paddle across the calm waters of Folsom Reservoir to reach a final boat ramp take-out. This section offers rest and reflection after the rapids, with scenic lake views and a wider river channel.

Note: Reservoir paddle-out may require longer time and good wind conditions.

Paddler Tips

Scout Rapids Before Running

Always inspect unfamiliar rapids, particularly the artificial features near the Pumping Station, to anticipate hazards and find safe lines.

Time Your Trip With Flow Levels

Flows between 800 and 1400 cfs offer an excellent balance of challenge and safety. Avoid high flows unless experienced, and be wary of low flows exposing hazards.

Plan Your Take-Out Early

Choose a take-out that fits your endurance; carrying boats at Oregon Bar is demanding, while reservoir paddling to Rattlesnake Bar is longer but less physically taxing.

Bring Hydration and Sun Protection

Exposure on the river can be intense; ensure you carry water and sun protection to stay comfortable on longer runs.
