I am wondering about the Hump as well, as one of my nieces is coming out on the boat, on the 16th.
I checked pacific anglers, Bonchovy and Predators Pen, for their reports and Dave said a few have been caught out there already. He seems to think april 10th will be the time. Bonchovy gave some dates in April that marked the start of it, April 4th one year, versus april 18th another year.
The water colours are very dark and obscured at the bell buoy and horseshoe bay now, and brown plankton/muck on the lines.
If you get a chance, just go!
Dave says Nanaimo is still dead.
