Sweetwater River
The Upper Sweetwater section covers a distance of 19 miles from Sweetwater Gap to Greys River. This section features Class III to IV rapids and offers challenging drops, tight turns, and boulder fields. The Middle Sweetwater section spans a distance of 18 miles from Greys River to Sweetwater Station. This segment features Class III rapids and a beautiful landscape with towering cliffs and stunning rock formations. The Lower Sweetwater section covers a distance of 31 miles from Sweetwater Station to the North Platte River. This segment features Class II to III rapids and offers an exciting journey with long stretches of calm water.
There are specific regulations that paddlers must adhere to when rafting on the Sweetwater River. For instance, all flotation devices must be Coast Guard-approved, and paddlers must wear life jackets at all times. Additionally, paddlers must carry a spare paddle, a whistle, and a throw rope at all times. Paddlers must also obtain a permit from the Bureau of Land Management before embarking on their journey. Overall, the Sweetwater River provides an exhilarating and challenging whitewater experience for paddlers of all skill levels.
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 Sweetwater River 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.
