In reply to girlymonkey:
I've crossed the river after a 14 hour day, rained all day, got there at midnight, midges gathering in the manky hut beside Luibeilt........
Anyhoo was doubtful about the crossing, but the river calms down a bit 50m downstream from Luibeilt. In up to my waist but the water there wasn't especially turbulent, just wide and deep, and felt safe enough for the most part.
