I had spawning culverts, but got no fingerlings, probably because of bluegill predation. BG will readily eat all the hatchlings as they leave the nest in a ball, as will small LMB. I have had bad predation from otters so restocking is probably not an option, at least not at this time. I have recently heard of otter problems around here where they come up an intermittent feeder creek a mile from the local rivers. I am closer than that. If you restock, I would suggest getting advanced size 11-12" CC to minimize bass predation. Those could be stocked in March and harvested in October at eating sizes.
