Chaoborus
This must be Chaoborus. In colloquial terms, the hairy nose in combination with the generally pale color and normal proportion legs put it there. (One genus has a short, bare nose. Another is darker. Another has a very short basitarsus.)

Possibilities include C. trivittatus and C. americanus.

Closer?
Can you post a closer shot of the wing veins, showing the R-M and M-Cu crossveins, forking of M (if any), and any branches of R near the top?

Wing shot added
Let me know if the wing shot shows what you need to see, when you view the larger image.

Chaoboridae
The adult wing keys to Chaoboridae. It has too many veins for Chironomidae. I do not have a key to the pupa or adult of the family, only larva.

Pupa does look chaoborid
There is a key to aquatic fly pupae in Merritt and Cummins. The spindle-shaped respiratory horns (the antenna-like structures) with nearly closed apical openings are diagnostic for the family.

Not a chironomid
The wing closeup is helpful. This is not a chironomid. I think it is Chaoboridae. I'll look it up later.
