BURLINGTON, Maine — Lincoln resident Jerry Davis apparently got caught in his own wake on Upper Cold Stream Pond and it caused him to lose control of his boat, which crashed, ejecting him onto shore, Warden service spokesman Cpl. John MacDonald said Monday.

Davis, 53, is the town manager for Greenbush and is Lincoln’s former code enforcement officer.

Davis was driving his 15-foot 2006 Bombardier Seadoo at about 2:10 p.m. Sunday in an area of the pond called The Little Narrows, and witnesses saw him take a hard turn at a high rate of speed and get caught up in the wake created, MacDonald said.

“When he did that, it knocked him to the ground in the boat,” he said. “The boat continued on at a high rate of speed and crashed on shore, and the driver was ejected.”

The boat hit the shore near 51 Petite Road, and a nurse practitioner helped to render aid to Davis, who was seriously hurt. MacDonald did not have an update on his condition on Monday. No information was available about David, a hospital spokesperson said Monday.

Davis was taken by ambulance to Penobscot Valley Hospital and then a LifeFlight helicopter transported him to Eastern Maine Medical Center in Bangor, MacDonald had heard.

Upper Cold Stream Pond is one of two large bodies of water bisected by Transalpine and Long Ridge roads in Lincoln. A small part of it extends into Burlington.
