It depends on the kind of fishing you're doing. If you're using your trolling motor to pound the bank for SMB, LMB, or spawning Crappie we usually call it quits at around the 10mph windspeed mark. If trolling you can get away with a little more wind, but we don't do much trolling so I can't say what the top level would be. Be careful as the main channel can get worked up pretty quick while you're in a protected arm fishing, making it difficult and dangerous to get back to camp. We left Red Canyon for Farley once in the 80's and found that the Main Channel was rolling with 4' waves, I was just a kid and thought it was cool, but my Mom wasn't impressed and stuffed my brother and I under the bow. We were in a 16' StarCraft(aluminum) closed bow. Took quite a while to get back to Farley.
