I used to live in Pomona and go to cootharaba to sail our hobie cat. I reckon it's perfect for sailing/ windsurfing because the lake is quite shallow everywhere, maybe chest height, and it picks up wind really well. can't advise you on wind directions but we never had any problems going sailing. If there is wind around you'll pick it up there. it gets really choppy thou when it blows but thats gales. Have fun. I'm a bit jeallous of not lifing close enough to such a fantastic lake
