Colorado River Segment 4 river run
Colorado River Segment 4
This segment is approximately 10 miles long and offers several exciting rapids and obstacles. Some of the most notable rapids include Eye of the Needle, Funnel Falls, and Tombstone. These rapids offer a thrilling experience for experienced paddlers, but can be challenging for novice paddlers.
There are specific regulations in place for this area to ensure the safety of visitors. Personal flotation devices (PFDs) are required for all individuals on the river, and helmets are strongly recommended. Additionally, visitors must follow Leave No Trace principles and pack out all trash.
Plan your run down to the hour
Same weather feed Snoflo's iOS app uses -- updated continuously from NOAA / yr.no. Watch the precipitation column on the meteogram; rain ahead of a run typically lifts flows 12-48 hours later depending on the basin.

Whitewater safety
- Check the flow before you run
- Use the linked-gauge card and Regional Flow panel above. Class ratings change with flow -- a Class III at low water can become Class IV+ at high water.
- Know your skill ceiling
- Pick runs comfortably below your ceiling. Cold-water and big-water runs raise the consequences of any mistake.
- Wear the right gear
- Helmet, PFD, drysuit / wetsuit when water is below 60°F. Throw bag, knife, and whistle on your person, not in the boat.
- Scout, set safety, and run with a team
- Scout new rapids on foot, set safety with throw bags above the consequence pool, and run with at least one other competent paddler.
- Respect the river
- Strainers, undercuts, low-head dams, and wood can kill at any class rating. When in doubt, portage.
Set push alerts in the Snoflo app
Save Colorado River Segment 4 as a favorite, set a discharge threshold (e.g. "alert me when flow hits 600 cfs"), and the iOS app pushes the moment the linked gauge crosses.
