link above to the most recent F&G fishing report. Some bass may still be on beds in places on the big/cold lakes.
Also from AJ's bait and Tackles facebook post:
"Please take note that in NH it's 'catch & release' season for Bass and you CANNOT TARGET them with live bait (this includes worms)!
Black Bass (Smallmouth Bass & Largemouth Bass)
May 15th to June 15th.
Catch and release only.
Artificial lures and flies only."
good luck, and let us know how it goes
