Maine lakes are a resource of inestimable value: Maine’s great ponds produce $3.5 billion in spending every year; supply drinking water to half our population; provide employment for over 52,000 Mainers, pay for essential municipal services through property tax revenues, and make Maine’s unique way of life possible.
Maine lakes are fragile: a recent satellite survey showed many Maine lakes lost as much as 20% of their clarity between 1995 and 2010; 26% of Maine’s great ponds rich enough in nutrients to support significant algal blooms; 268 of our great ponds are on the Maine Department of Environmental Protection’s Lakes at Risk list, meaning that in a short time they may fail to provide expected recreation, aquatic habitat, and safety for human use unless we care for them better.

Maine Lakes could really use your help next Wednesday to pass this bill. Your grandchildren will thank you for it.
LD 40 Bans Fertilizer Next to Lakes
Mary Kretchmer, 8, along with her Dad, did an experiment with some water from the lake they monitor in New Hampshire. They added 1 teaspoon of 36/6/6/ fertilizer to one jar of Lake Wentworth water, none to another, put the 2 jars on a windowsill, stirred daily, and waited four weeks to see what would happen.
The two jars show Mary Kretchmer’s results.
The same thing could happen to waters here in Maine if we don’t take care of them.
Naturally forested lake shorelands have kept Maine’s lake water quality high until recent years. Today’s population pressures, accelerated by longer growing seasons and intense, more frequent rain events, threaten to affect our pristine waters in the ways shown at left. A recent satellite study of Maine lakes bore this out when it showed that many Maine lakes lost as much as 20% of their clarity between 1990 and 1995.
Unless we work together to shield our lakes from pollutants, water quality will decline. Continue reading

In 1970, there was no DEP, no shoreland zoning, and the Great Ponds Act was generally ignored as people dumped sand in their lakes to create beaches that could not last. Municipal sewage and industrial wastes were pouring into our rivers, streams, and lakes.
Times have changed! For 45 years, as COLA and now the Maine Lakes Society, we have advocated for strong but sensible regulations to protect the water quality and beauty of our lakes. Lakeshore property owners have accepted more stringent land use regulations because we know our lakes are fragile and our land use activities can impact the future of the waters we love. We accept regulation “for the sake of our lakes.” Continue reading
Maine’s freshwater lakes are under serious threat. A 2012 University of Maine study shows the clarity of many Maine lakes has declined as much as 20% since 1995. New evidence from Europe shows climate change is accelerating declines in water quality there.
If we do nothing, Maine’s lakes, long a precious asset to residents and those who visit Maine to enjoy them, could become not only a vanished treasure, but a costly liability. But we can do something to avert lake declines. LakeSmart is Maine Lakes’ answer to the freshwater challenge.

Global assessment shows 95% of lakes are warming
In 2010, National Geographic News reported on the results of the first comprehensive global study of lake temperature trends. The study — conducted by researchers at NASA’s Jet Propulsion Laboratory (JPL) in California using satellite data — found that in the last 25 years, the world’s largest lakes have been steadily warming, some by as much as 4°F (2.2°C). In some cases, the trend is twice as fast as the air temperature trend over the same period. Continue reading
