"You still have the same amount of depredation, natural death, etc, the only variable is the reduced number of eggs spawned and fertilized...........So, over harvest prior to the spawn can have an impact on the population."
I don't disagree with any of this, but in Utah it seems that you could have the worlds best, most successful spawn, and the larvae would either starve to death (in a less "rich" lake), hatch bountifully in flooded weeds/trees only to have the lake drawn down so far they have no cover, be born into a drawn down lake with no cover where they can't survive, or even have their eggs left high and dry on vegetation by an early draw down.
