Based on the information you provided, I would make an educated guess that fish at Skiatook can be much more spread out and scattered than fish at those other lakes. When the thermocline is shallow (20 feet down), it creates much less space/area for all fish to inhabit. There is basically a layer of water from the surface down to 20 feet for fish to live, breathe, and eat in during the summer. In a lake like Skiatook where the thermocline is much deeper, that layer of "quality" water (where fish can get enough oxygen to survive) is a great deal larger. My guess is that the shad can be a bit more scattered in Skiatook, as opposed to being much more tightly schooled in lakes with shallow thermoclines. This of course has an effect on how concentrated schools of hybrids are as they feed on the scattered versus schooled shad.
That is my initial impression of this situation, but others who fish Skiatook a lot may have additional info to add which woudl help explain it.
