Pike can be a little fickle at times. Ive had really good luck on that lake using a cheap yellow/green daredevil knockoff and letting it flutter when Im bringing it in. Reel fast till it gets close to the surface and keep your rod tip high, then stop reeling completely or else slow way down and the spoon will flutter down till it hits bottom, this is when they usually hit. Me and a buddy were there like 10 years ago with my boat and we couldnt get a bite to save our lives till we put on green/yellow spoons and stumbled upon this technique, then we absolutely hammered the fish till our arms got sore. That was back when the lake was loaded with 10lb fish, I dont think they are quite that big yet, since it winterkilled a while back. We went out there this spring and did quite well casting from shore, but it was mid june, If nothing else, take some smelt and throw them out on the bottom or under bobbers, or try frogs under bobbers....
