Dryanin's charr can reach a recorded maximum length of 90.0 cm (35.4 inches) and up to 8.3 kg (18.3 lbs).[3]

The body of Dryagin's charr is covered with a few large (about 1 cm) light orange spots of usually irregular shape.[4] The belly and underside of the head are white or light yellow. The pelvic and anal fins are reddish-brown. During the spawning season, the body colour of the fish becomes brighter.[5]
