There are lakes in N.H managed for Browns.A lot that I know are smaller lakes. Like Webster, Bow Lake. But a couple bigger ones come to mind. Massabesic and Lake Francis.I have never really heard of any large Brown"sCaught in these lake. But you can catch plenty in the 15" range. I know Massabic used to be loaded with shiners. And should be the best bet to catch a large brown.Don"t know if a trophy Brown lake would be possible.But it would be great to have a few.
