I don't know about Winnipesaukee in particular, but the NH state records for smallmout and largemouth are as follows:
Largemouth Bass 25.80" 10 lbs. 8 oz. Lake Potanipo Brookline 5/1967 G. Bullpitt NH
Smallmouth Bass 23.25" 7 lbs. 14.5 oz. Goose Pond Canaan 8/1970 Francis H. Lord MA
The complete list can be found at:

Check out the record white perch caught in Winni -- over 17 inches and a few ounces shy of four pounds!
I wonder what the record rock bass is...
