As Woodsy stated, there is no "10 foot rule".
You own to the high water mark. There are a number of RSAs that define the high water mark, and if in doubt the Department of Environmental Services is the keeper of record and has final say.
Without listing them all out again, you can find information under the 270 section of the boating laws and the 483 section environmental laws.
Look at the bright side....would you really want to pay the taxes on that extra ten foot buffer????
Hopefully the officer was confused or misunderstood the question....wouldn't want someone in a position of authority like that spreading improper information that may cause a landowner undue confusion, or possible legal issues!
