When in the field, we occasionally come across things that make us scratch our heads. You may recall that on September 11th, we sent an email about observing a turtle swimming across Norfork Lake. Being as it is 2020, we wanted to provide another unusual observation that occurred on Norfork Lake.
Freshwater Drum, often referred to as "gaspergou," are native to Arkansas. Commonly found in large rivers, lakes, and reservoirs, drum derives its name from mature males' ability to contract a unique set of muscles that vibrate against the swimming bladder to produce a loud drum-like sound. The Fishes of Arkansas and Fishes of Missouri books both indicated Freshwater Drum are present in all of the Upper White River reservoirs except for Norfork Lake, as well as in the White River below Bull Shoals Lake. Previous biologists have also indicated that they have never observed Freshwater Drum while sampling Norfork Lake. With the craziness of 2020, it isn't surprising that we just happened to collect several Freshwater Drum for the first time on Norfork Lake. Individuals were sampled in different areas of the reservoir while electrofishing for black bass this fall. Shortly after that, Darrell Binkley of Bink's Fintastic Guide Service called us to report catching one. In his 29 years of guiding, he said that was the first one he had caught on Norfork Lake. Though we are unsure how the Freshwater Drum got into Norfork lake, we do not believe the introduction will impact the existing fisheries in Norfork Lake.
