not actually all fact, water temperature, related to photo period ie daylight hours, is main trigger, trout and seatrout tend to be first, salmon second, but that depends on geographical distribution, however lower water will help, as fish will spawn in areas that are always underwater, therefore the lower the better at spawning time. in terms of flooding damaging the redds therefore the eggs, only a big problem if layers of silt are deposited on top of eggs, if eggs are washed out and settle on other gravel beds will hatch just the same.
