The Lake Attitash Watershed consists of the entire area that feeds water into Lake Attitash. All activity within this area affect the water quality of Lake Attitash. The map below shows the area from which water flows downhill into the lake.
If you live in the Lake Attitash Watershed, please be a good lake neighbor and be mindful of any fertilizer that is used on your property. Also, be mindful of pet waste, rock salt, car wash runoff, and yard waste. All of these factors can have major affects on yearly cyanobacteria blooms. Good lake neighborhood practices are described on the Lake Attitash Association water quality page.
If you see one of the blue “Entering Lake Attitash Watershed” signs while driving around, you know that you are in the immediate watershed of the lake. The further away areas of the watershed, such as those in Newton, New Hampshire, are not marked with signage.
