A big shout to Lloyd for getting this together. We could do with a shot of the medium high level at ahich the wardens hole starts to get decent for playboating - can any one can help with a number or picture?

@  1'  8"   (Reaverhill)

This is pretty much an absolute minimum flow for boating

@  2' 7"   (Reaverhill)

This level is a more sensible minimum flow, Wardens rapid will be worthwhile.

@  6' 11"   (Reaverhill)

High water. Wardens will be be bouncing down and the river flowing well elsewhere.
