Yes, Valley Creek does have little black stoneflies, particularly in one stretch about 200 yards long. They are probably already done for the spring. For whatever reason, the fish rarely eat them. I have no idea why not, as I've seen hundreds hatch while the trout keep midging. They're only in the one stretch (that I've seen), and they're only there for a week or so (that week would have been about 2-3 weeks ago), which may explain why they haven't become a regular part of the Valley Creek diet.
