I always imagined that "White Water" implied immense torrents of water, huge waves and dangerous obstacles. Quite like the terrifying courses laid out for the sport at the Olympic Games. I dont recall any of the watercourses in the vicinity coming anywhere near an approximation of that, except on the odd occaision when they are in serious flood following a prolonged spell of heavy rainfall, which would be far too unpredictable to base a tourist attraction/health activity on.

Or am I being too picky. Perhaps "white" refers not to the volume of water but to it's contamination with industrial pollutants, in which case the local watercourses would be eminently suitable, particularly the Calder.
