Safety details
American Whitewater rates Big Sur/Cameo Class III and describes the feature as a unique high-water wave that occurs around 20,000 cfs. This is expert high-water boating, not a casual float or beginner surf session.
- BoaterBeta lists 18,000 cfs minimum recommended, 20,000–24,000 cfs optimal, and 30,000 cfs maximum recommended. The 2012 Colorado River Basin study independently reports 20,000–50,000 cfs acceptable and 27,500–50,000 cfs optimal survey ranges. Treat the conservative 18,000–30,000 cfs band as planning guidance only and verify trend, forecast, debris, and the actual wave before launch.
- The downstream Roller Dam is a hard stop. Take out at the named access before the dam; do not surf, swim, or drift toward the structure, and do not improvise a shoreline exit or walk the railroad/I-70 corridor.
- High water creates fast current, powerful eddies, cold water, floating debris, limited recovery, and difficult shore access. Require a properly fitted PFD, cold-water protection, communication, rescue equipment, competent safety boaters, and a crew with proven high-water skills.
- The American Whitewater access coordinates and parking directions are approximate. Confirm the signed eastbound I-70 parking area, legal path to the river, take-out conditions, and any current closure or construction before unloading. Never stop, cross, or walk in active travel lanes.

Gauge note
Target band: 20,000 cfs to 24,000 cfs · Colorado River near Cameo, CO
Gauge context
Use direct USGS 09095500 Colorado River near Cameo for the flow check. Big Sur is a rare high-water feature: American Whitewater identifies it as a Class III reach that occurs around 20,000 cfs, while BoaterBeta lists 18,000 cfs minimum, 20,000–24,000 cfs optimal, and 30,000 cfs maximum recommended. Keep the route unavailable below 18,000 cfs, above 30,000 cfs, during rapid change or debris, when the dam boundary or access is unclear, or when the crew lacks expert high-water rescue readiness. These values are planning thresholds, not a safety guarantee.

Access and shuttle
A guarded expert Big Sur high-water wave reach with direct 09095500 telemetry, 18,000–30,000 cfs planning bounds and a 20,000–24,000 cfs preferred band, named access points, a hard Roller Dam take-out, and no endpoint camping.

Put-in
Beavertail Mountain cutoff / Beaver Tail Tunnel parking accessUse only the American Whitewater Beavertail/Beaver Tail Tunnel parking access and Roller Dam take-out contexts after confirming current signs, legal parking, river entry, and the physical landing. Coordinates are approximate planning anchors.
Take-out
Roller Dam take-out accessAmerican Whitewater’s put-in directions require an eastbound I-70 parking area and a walk under the overpass on the concrete bike path. Do not stop in travel lanes, cross I-70, walk active railroad tracks, or substitute private access.

Access caveats and watch for
Access caveats
- Use only the American Whitewater Beavertail/Beaver Tail Tunnel parking access and Roller Dam take-out contexts after confirming current signs, legal parking, river entry, and the physical landing. Coordinates are approximate planning anchors.
- American Whitewater’s put-in directions require an eastbound I-70 parking area and a walk under the overpass on the concrete bike path. Do not stop in travel lanes, cross I-70, walk active railroad tracks, or substitute private access.
- The Roller Dam is the mandatory endpoint boundary. Exit before the structure; a high-flow wave is not permission to approach, run, or swim toward the dam.
- No on-route camping is established. Stage a lawful shuttle and separate lodging/campground plan before the high-flow window; do not rely on an overnight vehicle or riverbank camp.
Watch for
- USGS 09095500 below 18,000 cfs, above 30,000 cfs, rapidly rising/falling, unavailable, or inconsistent with the feature’s current visual shape and local advice
- Powerful high-water current, wave hydraulics, cold water, floating debris, strainers, limited recovery, I-70/railroad exposure, and the Roller Dam
- Eastbound parking/path legality, access closures, take-out visibility, safety-boat positioning, daylight, and failure to exit before the dam

Score & sources
Why this score

Why this scoreToday's evidence strength is checking
Evidence strength mostly comes down to three things: how direct the active gauge is, how clear the range is, and how fresh the data is.
- Checking evidence-strength notes.
- Checking evidence cautions.

NotesWhat to know before you go
These notes cover the access details, route quirks, and source caveats most likely to matter once you get there.
- Named public corridorBig Sur / Cameo-Lucky 7; approximately 1.2 miles; Class III
American Whitewater names Big Sur/Cameo, the Class III rating, the 1.2-mile reach, the direct Colorado River near Cameo gauge, and both access points. BoaterBeta independently names the Beaver Tail Tunnel-to-Roller Dam segment.
- Direct live gauge and high-water gateUSGS 09095500; 18,000 cfs minimum, 20,000–24,000 cfs preferred, 30,000 cfs maximum planning band
USGS provides continuous discharge and gage-height telemetry. BoaterBeta publishes 18,000/20,000–24,000/30,000 cfs guidance, while American Whitewater identifies the feature around 20,000 cfs and the federal basin study provides an independent high-flow survey range. These values are planning cues, not a safety envelope.
- Lawful endpoint accessBeavertail Mountain cutoff parking/path access to Roller Dam take-out
American Whitewater documents the eastbound I-70 parking/path approach and publishes approximate put-in and take-out coordinates. Verify current legal parking, carry-down, landing, closures, and dam restrictions before entering.
- Safety boundaryExpert Class III high-water feature with mandatory Roller Dam exit
American Whitewater identifies the high-water Class III feature; Rock2Rapid warns of fast current, limited shore recovery, and the danger of ending up near the dam or illegal railroad corridor. Preserve the high-water rescue and hard-stop warnings.
- Camping and logisticsNo endpoint camping; roadside/dam-adjacent day use only
The named access contexts are a highway parking/path and dam-adjacent take-out. No camping evidence clears the route; use separate lawful lodging or a designated campground and stage the take-out before the high-flow window.
- Rights-clean image decisionApproved USGS public-domain Cameo webcam image
USGS identifies the 09095500 webcam image as public domain. Use it as current Cameo corridor context, not as a claim that it depicts the Big Sur wave or either endpoint; retain the USGS source attribution.
- Duplicate separationDistinct Cameo high-water feature below the Glenwood/South Canyon route family
This route is separate from the existing Grizzly Creek-to-Two Rivers and Two Rivers-to-South Canyon corridors: it uses the direct Cameo station 09095500, a different named high-water feature, and a separate Beaver Tail/Roller Dam endpoint pair.
