Water quality in Sebec Lake, Maine
The water quality of Sebec Lake is above average for lakes in Maine, according to the Maine DEP. A constant concern is to keep invasive species out of the lake. These are introduced by boats which are brought to the lake with remnants of the invasive plants (e.g. milfoil, hydrilla) somewhere on the boat, motor or trailer. It is important to inspect and clean boats which have been in other bodies of water prior to launching them on the lake.
