Soda Springs trailhead, Umpqua National Forest, Douglas County, Oregon, USA

Size: 5-7mm
I can't find any flies in Bug Guide with long antenna like this. The tiny fly was present on very shallow moving water. The big flume at this location has been leaking a steady stream of water about one foot wide and one inch deep. I also photographed what I think is a marsh fly at this location, which I'll submit in a few minutes.

Moved from Tachytrechus.

Antennae
The antennae may be species-specific, a "male secondary sexual character". I will need to do some reading. Females have plain antennae.
