Open water fishing season is now open under an emergency law signed by Gov. John E. Baldacci today. That’s one week early. All lakes, ponds and brooks are open except those with specific opening-day regulations that start after April 1. Open water fishing season historically begins on April 1st, on most waters of the state, but because of the warm weather opening up waterways in many counties and strong interest in wanting to fish, emergency legislation was enacted to start the season early.
