Unfortunately there is nothing like AWW, we mainly use this book https://westerncanoekayak.com/whitewater-in-southwest-bc-by-claudia-schwab/
Also, http://www.liquidlore.com/bc/
http://www.bc-ww.com/index.php/river-guide/bc-mainland-rivers/ (However sometimes these sites focus more on Class IV-V)
The Thompson in Lytton is currently running (Class III)
The Upper Cheakamus in Whistler is running (Class IV)
A lot of rivers have dropped out by now, but there's definitely still stuff to paddle. For example you could a tide at the Skookumchuck narrows.
