Muddy River (Sebago Lake)

Trickey Pond is a water body in the U.S. state of Maine. Its maximum depth is 55 feet (17 m). The lack of serious pollution in the area contributes to the pond's remarkably good water clarity. At most points in the pond, the entire depth can be seen.

Brandy Pond, also known as Bay of Naples Lake, is a small lake in Naples, Maine, United States, that is connected to Long Lake by the Chute River. Brandy Pond is connected to Sebago Lake by the Songo River, which runs through Sebago Lake State Park. To get to Sebago Lake through the Songo River, one must pass through Songo Lock, one of the last remaining hand-operated locks in the country. Brandy Pond is bounded by a commercial (downtown) area called the "causeway" on Rt. 302, an area of homes on the southerly side called Scenic Drive, a golf course on the northern side, as well as many private homes and public campgrounds and condominiums.

Songo Lock is the last surviving lock of the Cumberland and Oxford Canal, a 19th-century canal in southern Maine, United States. The lock is located on the Songo River, just above its confluence with the Crooked River at the northern end of Sebago Lake State Park in the town of Naples. The lock, built in 1830, is now used primarily during the summer months by pleasure craft. It was listed on the National Register of Historic Places in 1970 and designated as a Maine Historic Civil Engineering Landmark by the American Society of Civil Engineers in 2001.

The Crooked River is a 58.0-mile-long (93.3 km) tributary of the Songo River in Maine. It is the longest of the tributaries of Sebago Lake, the outlet of which is the Presumpscot River, flowing to Casco Bay on the Atlantic Ocean. The Crooked River rises at the outlet of Songo Pond in the unorganized territory of South Oxford in Oxford County, near the eastern end of the White Mountain National Forest. It flows southeast through the towns of Waterford, Norway, Otisfield, Harrison in Cumberland County, Naples, and Casco, reaching the Songo River 1.0 mile (1.6 km) south of that river's source at the outlet of Brandy Pond and 2.1 miles (3.4 km) upstream from the mouth of the Songo in Sebago Lake.

Peabody Pond extends from the southern tip of Bridgton into northern Sebago forming the western boundary of Naples, Maine. The eastern tip of the lake receives drainage from Cold Rain Pond in Naples. The southern tip of the lake overflows as the Northwest River through 5 miles (8.0 km) of boggy land to the western shore of Sebago Lake at East Sebago. The pond has a native population of rainbow smelt, and has been stocked with smallmouth bass, lake trout, and land-locked Atlantic salmon. A boat-launching area near the outlet of the lake is accessible from Tiger Hill Road off Maine State Route 107.

The Songo River is a 3.1-mile-long (5.0 km) river in Maine. The river flows from Brandy Pond at the south end of Long Lake into Sebago Lake at Sebago Lake State Park. Songo Lock, the last remaining lock of the 19th-century Cumberland and Oxford Canal, controls the elevation of Long Lake and allows navigation of large boats between Long Lake and Sebago Lake.

Sebago Lake State Park is a public recreation area encompassing 1,342 acres (543 ha) on the north shore of Sebago Lake in the towns of Naples and Casco, Cumberland County, Maine. It opened in 1938 as one of Maine's original five state parks. The mostly forested park is divided into east and west sections by the Songo River. It is managed by the Maine Department of Agriculture, Conservation and Forestry.

Camp O-AT-KA is a non-profit summer camp for boys in East Sebago, Maine, on the western shore of Sebago Lake. Founded in 1906 by Rev. Ernest Joseph Dennen of Lynn, Massachusetts, it is to date the oldest continuously running summer camp in the United States. It began its life as the summer camp of the Order of Sir Galahad, an Episcopal church organization founded by Dennen in 1896. Originally founded as an explicitly Episcopalian camp, O-AT-KA may have allowed some Jewish campers as well. In the modern period, it is open to campers of all backgrounds. It runs as a traditional summer camp for boys aged 7-16 and is accredited with the American Camp Association.During the off-season, O-AT-KA is also a popular venue for weddings and other events. It has been featured on Martha Stewart's website, described as making one, "feel like you stepped into a Wes Anderson film."

Point Sebago Resort is located in the Town of Casco, on the north shore of Sebago Lake, southern Maine's largest lake. Point Sebago opened in 1970 as a campground suitable for tents and trailers. Today the 775-acre (3 km2) resort has over 250 park homes on and around Sebago Lake, resort cottages and vacation homes on and around the 18-hole championship golf course. The Resort offers free supervised children's activities program, as well as family and adult activities to resort guests, and an off Broadway caliber entertainment program. Sebago Lake State Park lies just to its west. The resort was started in 1970 by Larry Gould, who lived on the shore of the lake from 2008 until his death from a long-standing illness on February 13, 2015. The resort is now owned by Cove Communities.

The Chewonki Foundation is a non-profit institution in Wiscasset, Maine which runs educational programs with an environmental focus.
