The plane crashed into Ridgway Reservoir in a mountainous area in southwestern Colorado on Saturday. The single-engine Socata TBM700 was en route to Montrose, Colo., about 20 miles north of the reservoir, from Gadsden, Ala.
Marti Whitmore, a spokeswoman for Ouray County, said poor visibility underwater hampered the search Sunday. The rescue team hoped the camera would help assess what equipment would be needed to get the wreckage to the surface.
"Logistical questions are being focused on today," she said. "This morning we sent a camera down to get more detailed information to determine if the fuselage still in one piece, or broken, is the wing damaged."
Whitmore said the reservoir is about 7,000 feet above sea level, increasing the chance divers could suffer from the bends.
The plane was registered to Gadsden Aviation LLC. Its flight records show took off at 8:30 a.m. and crashed shortly after noon after landing in Bartlesville, Okla.
