A 12-year-old boy from Calvert County has landed in Maryland’s fishing record book for a catch made with a spinning rod one summer evening at a local pond: a largemouth bass that weighed 11 pounds, 6 ounces.

Colton Lambert’s catch on July 31 — weighed the next day at a tackle shop in Chesapeake Beach and authenticated by a biologist from the state fisheries service — was announced last week by the Maryland Department of Natural Resources. The weight was four ounces heavier than the previous state record for freshwater largemouth bass set nearly 30 years ago.

Colton, of Huntingtown, will be honored Saturday at a seafood festival at Sandy Point State Park in Annapolis. The Lambert family could not be reached for comment on Colton’s feat at a Huntingtown farm pond.

“It was a beautiful fish, I can tell you that,” George Klein, owner of Tyler’s Tackle, who weighed the catch on a state-certified scale, said Sunday. It measured 26 inches long and 18 inches around.

The reaction from the young angler?

“He was very excited,” Klein said. “The father was even more excited than the boy was.”

A state news release gave this account:

“Colton was fishing with his father and younger brother at approximately 7:30 p.m. when he thought his line was caught on something.

“ ‘All of a sudden something started to move very quickly and broke the surface and took off, peeling line off the reel,’ he said. ‘It was really hard to control and reel in; when I finally slid it up on the shallow bank, my dad started getting all excited.’ ”

The catch was made, the state said, with a “spinning rod loaded with an 8-pound test line and a plastic worm, rigged weedless and without a weight.”

Virginia’s state record for largemouth bass is 16 pounds, 4 ounces, for a fish caught in 1985.
