American Whitewater.org has 13 sections of the Buffalo listed. 12 of the 13 are noted as "Below Recom" (i.e. too low in thier opinion) and the 13th section is "Lower Runnable"
in any case, you can see the start/end locations and mileage for each section, and the class rating they have
you might want to court those outfitters a little more and see if there are other options - maybe the White ? or shift to Missouri where there are spring fed rivers that are likely more runnable right now
you can also just google for the USGS Buffalo River gauges - they will present the current cfs with an indication of where nortmal flow would be for the same days over the history of the gauge, but that does not give you any idication that it is too low or not.
