As fossana suggested, that gauge is a horrible representation of what to expect between Harris and Coyote. Death Hollow, Calf Creek, Boulder Creek, Deer Creek, etc. all come in upstream and will be adding a lot of flow. Good advice to call the visitor center in Escalante, but your chances are still crap for mid-May this year. Even in drier times, that section can have enough water to make travel quite challenging, especially downstream from Ringtail where social trails are fewer and harder to find. Just fighting your way in and out of the river through the willows can take it out of you fast. That section is much better done in a packraft, or at least not in the spring of a record-setting water year. Also, the section from Harris/Fence down is frequently packrafted at much lower than 5cfs on the town gauge.
