Fewer private launches available in 2002 due to commercial sector using more of their launches, especially in May and June. The 84 miles trip from Sand Wash to Swaseys Rapid offers outstanding scenery, interesting geologic formations, evidence of prehistoric and historic human activity, and whitewater opportunities. The average trip length for private boaters is 6 to 7 days. During the spring season, boaters should be prepared for a wide variety of weather conditions as a single trip may include snow, rain, and cold nights as well as warm, sunny days. Summer temperatures may exceed 100 degrees.
Thunderstorms can build in a matter of hours and produce heavy rain and flash floods.
Fall is unpredictable. Ice blocks the river from December though mid-March. Running water is generally available at Rock Creek, Range Creek, Chandler Canyon, and Florence Creek. Springs are available in a forked side canyon near the second camp around Peters Point, at Dripping Springs, at the south end of Trail Canyon Bottom, and at McPherson Ranch. All water obtained in the canyon should be treated.
