Water levels?

Isn't there a restiction on messing with the dam once the spawn begins? It's my understanding that years ago if the water was high they would let more water into Canyon and it effected the success rate of the walleye spawn and visversa on low water conditions. they would try and hold more water back for the chain of lakes thus dropping the level in Canyon and then the eggs would be effected also.
