Don't know if this may have any bearing but sometimes large reservoirs go through a boom in forage during and subsequent to flood years. There is an increase in fertility and predators benefit but lag in the process. Eventually after a big growth spurt and reproduction of predators the fertility declines and all the big fish are trying to hold their own. Maybe this is just a natural decline in fertility that is affecting the larger fish.
