No, it wasn't on the warm side. It was kind of nice, because the few people that were out on a Thursday seemed to keep toward that side of the lake, which left the rest of it to me! I started on the cove just across from the marina and caught three in there on a blue shad crankbait (The same one in my picture). I lost the bait a couple of casts later, something underwater cut my line. That really made me mad, since I didn't have another one. I wasn't getting any action on the other two colors I tried in the coves, so I headed to the riprap around the dam and tied up a Crappie colored crankbait, as that was the closest thing to a shad that I had left, and ended up catching the other eight on that lure. Today I am painting up two more "Clinton Lake Shad" lures, similar to my Crappie pattern, but with more of a shad style to them.
So, I guess it's not much of a secret anymore, but hopefully that will work for you.
