The Private Waterfront area is 250' with a 35 foot dock. The Lake
tends to stay warm for a Maine Lake and drops off slowly. It is about
6 to 10 feet deep at the end of the dock. Plenty of Swimming and
Outdoor Activities are available. There is a boat landing at the bridge about 1 1/2 miles up from the camp if you have your own boat. Otherwise, a boat and motor or canoe is provided for your enjoyment. New for Summer of 2019, new kayak, regular electric line (Solar will be there for backup only. No more monitoring electric meter). New Refrigerator. Camp is open from June 15th to October 30th every year. Smoking is not allowed; if you or your guests smoke inside, you will be billed for the damages.

Mainstream is not commercial and abounds with wildlife, including Moose, Deer, and Beavers, as well as a large variety of Birds.

We have added a two person kayak and a child kayak plus two rowboats and a canoe for the Summer of 2023. We already had a canoe and boat available. Also, we are extending our dock out 50 feet from shore for better swimming.
The Portland Press Herald has listed Mainstream Pond in Harmony and its associated river chain as one of the top 5 locations for kayaking and canoeing in the State of Maine. if you enjoy seeing bald eagles fly over and beaver building their lodges as well as plenty of recreational opportunities then Mainstream is a great place to get away

The fishing is excellent if you like Bass and Pickerel. We are only
minutes from the Harmony General Store which also has laundry facilities? Mainstream is part of the Sebasticook River Chain and has rapid falls below the Mainstream bridge.
