True enough SH, but I think it's important to note that Ma Nature didn't plan on a fisheries' model to allow "just enough" fish in the system to carry things onward.

No question, there will be some lost spawn in some areas (no digging method will ensure that a redd in one foot of water that is now a 7-8 foot deep spot will survive), ... hopefully, there were enough to start with that we won't all see the effects down the road.
