Colorado River

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.

These are the live readings and threshold notes behind today's score.

These notes cover the access details, route quirks, and source caveats most likely to matter once you get there.

• Named public corridorRiverbend Park to Corn Lake State Park; approximately 6.5–7 miles; Class I/II

  The Colorado Mesa river guide names the Palisade-to-Corn Lake section, identifies Riverbend as the preferred start below the diversion, gives the Class I/II rating and length context, and names Corn Lake as the take-out. A current local section guide independently describes Riverbend-to-Corn Lake as a 6.5-mile float.

• Direct live gauge and threshold gateUSGS 09106150; 500 cfs conservative floor, 1,500–15,000 cfs preferred, 30,000 cfs high-water stop

  USGS identifies 09106150 as a continuously monitored Colorado River station below the Grand Valley Diversion near Palisade. BoaterBeta publishes 1,500 cfs minimum recommended, 3,000–15,000 cfs optimal, and 30,000 cfs maximum guidance; local guidance documents lower-flow floatability but also low-water hazards. Keep the mixed-source values as planning bounds only.

• Lawful endpoint accessRiverbend Park / Harky's Launch public ramp to CPW Corn Lake river ramp

  The riverfront map identifies Riverbend Park and its boat ramp, while CPW documents the Corn Lake river ramp, road approach, park hours, and river recreation use. Coordinates are mapping anchors and must be verified against current signs, carry paths, parking, and closures.

• Safety boundaryMoving Class I/II water with low-water debris, diversion/bridge features, strainers, and high-flow consequences

  Rock2Rapid documents submerged farm equipment and changing low/high-flow hazards; the local guide documents the boulder diversion and a Class II riffle; Mesa County Search and Rescue stresses PFDs and river-designed equipment after a Corn Lake rescue. Preserve active scouting and no-ankle-leash guidance.

• Camping and logisticsDay-use endpoints; no route camping; CPW Corn Lake vehicle-pass and no-camping rules apply

  CPW identifies Corn Lake as day-use only and expressly prohibits camping. Stage a lawful vehicle shuttle and arrange separate lodging or a designated campground.

• Rights-clean image decisionApproved USGS public-domain Colorado River near Grand Junction image

  USGS identifies the Colorado River near Grand Junction image as public domain. Use it as Grand Valley river-corridor context, not as a claim that it depicts the exact Riverbend ramp, Corn Lake ramp, or submerged hazard.

• Duplicate separationDistinct Palisade-to-Corn-Lake direct-gauge reach below the diversion

  This route is distinct from the existing 09095500 Cameo Big Sur feature, upper Colorado reaches, Glenwood Springs routes, and the broad American Whitewater Grand Junction Town run: it uses the direct Palisade station 09106150, starts at Riverbend below the diversion, and ends at the named CPW Corn Lake ramp.
