The country vocalist had been missing for more than a week after going duck hunting.
The Oklahoma Highway Patrol confirmed to NBC affiliate KFOR that he was found dead in the lake.
His wife tweeted about the death, saying he is "safe with his Father in Heaven."
#CraigStrickland was found today. He is safe with his Father in Heaven. Thank you Lord for leading us to him today. I will praise you, Amen.
