Default Check out LWA (Lake Winnipesaukee Association

The Lake Winnipesaukee Association is a great resource to learn about the ecology of the lake watershed and ongoing efforts to maintain water quality.

LWA studies show that storm water runoff is by far the most damaging element to water quality. It brings both phosphorus and silt into the lake, adding algae to the food chain, which lowers water quality. Septic systems and fertilizer are also contributors and as this thread points out, there are some localized issues too.

Tomorrow (Saturday 8/29) it is supposed to rain about an inch. If you are at the lake, look for erosion taking place. If you can find sheets of water running into the lake, look for new silt deposits nearby. That is evidence of lake pollution. During "gully washer" thunderstorms and three day steady rains, the evidence is more clear.

The lake will age no matter if people are here or not, but it ages a lot faster when development channels water to the lake. The more that shore front property owners can reduce the impact of storm water runoff from their land, the less quickly the lake will age.
