Hey everyone. Just joined the forum. I'm in N. California about 40 min. from Berryessa. Just bought a brand new 20' Suntracker Fishin' Barge with an added wireless minnkota. I just installed a Scotty manual downrigger on the aft platform. I've been trying to read up as much as I can on Koke fishing and took the boat out 2 days ago and got skunked on Berryessa. Looking forward to getting some good tips and advice. If anyone in my area likes fishing for kokes and can teach me how to cath them, I would be more than happy to take you out on my boat on my dime for the lesson.
