At the 2022 annual meeting, Bob Gogolen mentioned that NH Lakes offers something called the Lake Smart Program, which will come to your property to analyze how lake-friendly your property is and provide an evaluation report. If there are actions that you can take to improve your property, the report will suggest upgrades.
NH Lakes has more information about this program at this web site: https://nhlakes.org/lakesmart/
