I agree with n8ly, although I know that pike are very aggressive and will sometimes go out of it's way to bite. Yet, these are lures we're talking about so the fish don't have to try too hard to catch them. Match the hatch is a good motto, definitely try it but also try variations, sometimes it is what is different and stands out in movement and color that will get fish to bite. It seems minnow fishing had some success.
Pike love rocky shorelines, points and aquatic vegetation. Does this lake have a flooded spring marsh? Because that's were they reproduce very early in the year when the water temperature is around 48 degrees. Try running a seine through there in the spring to see if there is any reproduction going on.
After a quick visit to Wikipedia I also found this. Pike use a lateral line system to register low frequency vibrations. They seem to recommend spinners to use this. Also, funfact: In Finland, catching a kymppihauki, a pike weighing at least 10 kilograms (22 lb), is considered the qualification as a master fisherman. Have fun.
