A blizzard of mayflies have invaded Kittanning in Armstrong County along the Allegheny River again this year. Although they are a nuisance to many, Mayflies are actually a sign that water quality has improved in the river.

Millions of Mayflies made driving and even walking hazardous in Kittanning, but after a few days they all died and all that was left was to cleanup.
