Not sure exactly which one your lookin for but....the runs I've done are from the hatchery (sappho) down to maxfield rd launch (bridge and its fairly steep). From maxfield down to Whitcomb-Dimmel take out, which is the one I think your looking for. And from whitcomb-dimmel to the sorting yards, then there is still a chunk of river below the sorting yards down to lyndecker. Sappho to maxfield approx 6.5 -7.5 miles, maxfield to whotcomb-dimmel approx 4.5-5 miles, and whitcomb-dimmel to sorting yards approx 6-7 miles. Hope i helped a little.
