Well there still are smelt....especially in Lake superior and Huron....but it is true that the runs are nothing compared to the days of old. Based on all the info i've read about loss of desporia, loss of spawning habitat, and other factors I would have to say that there will be no miraculous rebound for Great Lakes smelt. But who knows, baitfish are cyclical like anything else. Right now Lake Michigan is up on Alewives while Lake Huron is way down. The low alewive pop. on lake huron has allowed a bumber crop of young perch to explode, maybe the same could happen with smelt. So the truth is my opinion is NO but i'm not sure anyone can answer that question for sure.
