Probably not Isoperla
This looks like Agnetina to me (a perlid). The yellow wing bases are usually attributed to A. flavescens, and this could be a dark specimen. A. annulipes and A. capitata are also found in the DC area, and capitata has many synonyms and a rather variable appearance as an adult.

Isoperla
Looks a lot like Isoperla (Perlodidae). In a key for Utah, (this will be a big help), I.patricia adult males have patches of short stout hairs on the rear margin of the 9th tergite and the abdominal segments often have a red cast. The females have a wide, deep excavation on the subgenital plate and the abdominal segment red cast. If only this information was easy to photograph in the field.
