New Hampshire Lakefront Property Lake Quality Guide

Lakes make up some of the most valuable and utilized water resources in New Hampshire.

Chemical and physical aspects of a lake, and the biological cycles and components of a lake play an important role in determining water quality. Food chains directly affect the fisheries and wildlife capacity of a lake. The type and abundance of plants and algae can and do affect the planned uses of a lake. Monitoring biological components is important to understanding and managing New Hampshire's beautiful lakes.
