Watershed Information

Q: What is a watershed?

A: Everyone lives in a watershed, no matter how much water is nearby. The 30 Mile River Watershed is all the area that drains through the Dead River into the Androscoggin River. This area includes everything within its boundaries: the land, water, plants, animals, buildings, farms, roads and people. Everything that happens in a lake’s watershed eventually impacts the lake’s water quality, for better or worse.

Q: What is the 30 Mile RiverWatershed?

A: The Thirty Mile River is a waterway used long ago by Native Americans and pioneers traveling from the Androscoggin River to the Sandy River Valley. The name dates back to around the 1750s, when timber hunters paddled from Lewiston up the Androscoggin River to the north end of Echo Lake in what is now the town of Mt. Vernon. Estimating they had traveled 30 miles, they named the chain of lakes, ponds and streams the Thirty Mile River.


Numerous town officials and lake association members in the 30 Mile River Watershed, from Kimball Pond down to the Androscoggin Dead Water, joined to form a non-profit corporation to protect and preserve the watershed. Vienna's eight-year lake warden and courtesy boat inspection program was the local model, and the group sought out other organizations in Maine during its planning.

In January, 2008 the organization became a nonprofit corporation in Maine and in July of that year became a 501c3 federal nonprofit.
