Even when there are hatches, bait or the right lure will take trout in streams, unless the hatch is one of those events where there is just so much food available that all the fish in the stream are keying on it and nothing else

Very few trout when hungry will pass up a live worm or minnow, crayfish,Hellgramite, etcz, unless they are 100% keyed on one food source alone to the exclusion of everything else.. I have seen this a few times over the years, but in my particular experience, its not all the common.. Natural bait, or good convincing artificials are at least as effective as a good fly presentation in most eastern streams most of the time... bob
