Ran across this stonefly 2 winters ago, 2/16/19, on the Tucannon River across from Blue Lake. Should have gotten more pictures but I believe it to be a little brown stonefly. The day was somewhat mild and overcast for the most part.

The following winter I used this rig to take several rainbows from different spots of the same characteristics. All below a straight gravel riffle. Most of the day the dropper was a smaller similar black stone. The rainbows all took the Pat's, the whitefish all on that short (had to keep it down but lifelike) black dropper fly.

It does look to be in the family Nemouridae, but there are quite a few other genus possibilities (like Zapada and Malenka) in addition to Nemoura, and getting to that level of detail from a picture is difficult.

The snow leads me to believe it is the species Taeniopterygidae, commonly known as winter stoneflies or snow stones.

It's either that or an Atlantic salmon, take your pick. ;) :D
