Thanks John
I've found adult Chrysops cincticornis at this same location before, so that's a real possibility.

Aquatic Fly Larva
This is a larva of a deer fly (Chrysops). Larvae of some deer fly species have a terminal spine. There are a few species that have larvae found in flowing streams. Based on the pubescence pattern of the last abdominal segment, I would guess Chrysops cincticornis Walker, but that is just a guess.

You wouldn't happen to know why they have retractile spines coming from their respiratory siphons, would you? This seems like a feature that would be... counter productive to breathing.
