The men were identified as 19-year-old Dylan Peters and 23-year-old Chris Romey. Authorities say the two died when they attempted to swim between two islands on the north side of the lake. Their bodies were recovered Sunday night.
Scotts Bluff County Attorney Doug Warner says the men's bodies were found in a shallow area, about 6 feet deep. He says drugs and alcohol weren't factors in the drowning.
The Nebraska State Patrol and Scotts Bluff County sheriff's office are investigating the incident.
