If you fish it when it is low and clear you want to use light line like 6lb maxima or flourocarbon with a small float like an adjust-a-bublbe or small drennan, use split shot for weight and roe or small lures. You could also try casting small lures with a spinning rod and no float. The trick is to be stealthy. It also helps to switch up your presentation and try something that they haven't seen before (be creative). It is very tough fishing though to say the least. I would also recommend fishing for them early or late in the day when the water is this low because the coho are more leary during the day and are easily spooked fish to begin with. Good luck if you decide to go and again be very careful. You may see people fishing off the ciffs but I would not recommend that for a few reason, #1 being your safety. A person dies on the Cap every year. I would highly recommend casting spoons and buzzbombs at the mouth at this time of year.
