This is a great question Bob. This can be a problem most salmon fisherman face and struggle to find the answer to. Here are a few things to try when trying to locate more than one fish. - Talk to the bait shop and get a general knowledge of the depth range people are fishing(not always the best option but can give you a good starting point) - Talk to everyone you see at the ramp or on the way out the channel that looks like they were salmon fishing. - If you still don't have a clue what depth to start, begin trolling shallow and head west untill you hit fish. - Scrape the bottom all the way to the top of the water column until you know what depth they are hanging in. -TRUST YOUR FISH FINDER, if it found no fish use it to find the fish. Don't fish where there is no other fish. - Don't stay in one area too long if you don't get any more hits move on and find more fish. If you caught fish in 100ft don't stay there all day, you might of caught a fish heading deep or moving in shallow. - Get a lucky charm...ex: hat, sunglasses, rabbits foot, underwear...etc and stick to it. - Go with your gut feeling and don't always follow the other boats out there. - Fish the prime times sun up and sun down. Mid day fish can get spotty. Good luck, I hope this helps
