Kettle Creek macroinvertebrates

Spent a week inventorying stream restoration structures on Kettle Creek. A variety of structures have been used by the watershed group to reduce bank erosion and improve trout habitat. I've looked a many streams in north-central Pennsylvania and these structures are holding up better than most. Here's an example of a cross-vein type structure in the upper catch-and-release section of the stream:

We were focusing on the channel morphology and so didn't have time to turn over many rocks or assess fish populations. Nevertheless, we saw a lot of macroinvertebrates and all indications are that this is healthy trout stream which has recovered nicely following decades of intense logging around the turn of the century. Here are some photos of caddis, mayfly, dragonfly larvae:
