Fitch's General Store and House is a historic former commercial establishment on Long Hill Road in the village of East Sebago, Maine. Built about 1870 as a private residence, it became a general store in 1920 and was a mainstay of local business in the rural community. The property was listed on the National Register of Historic Places in 1995. As of 2014, it was apparently again a private residence.

Sebago is a town in Cumberland County, Maine, United States. The population was 1,911 at the 2020 census. It is part of the Portland–South Portland–Biddeford, Maine metropolitan statistical area.

Douglas Mountain or Douglas Hill is a small mountain in the towns of Sebago, Maine and Baldwin, Maine in the United States. It is named after early European settlers John and Andrew Douglas and was first settled by United States citizens in the 1830s. It is part of a small range called the Saddleback Hills on the west side of Sebago Lake. The peak of the mountain is the second highest point in Cumberland County, Maine In 1892, the mountain and surrounding area was purchased by Dr. William Blackman, a New York surgeon. He constructed a sixteen-foot stone tower at the summit, which provides striking panoramic views of Sebago Lake, the Presidential Mountains, and the city of Portland, as well as much of the Western Maine lakes and foothills. The Nature Conservancy later purchased and protected the land from development and later handed over its ownership to the town of Sebago for public recreation.

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 (Sih-Bay-Goh) is the deepest and second-largest lake in the U.S. state of Maine. The lake is 316 feet (96 m) deep at its deepest point, with a mean depth of 101 feet (31 m). It is possible that Sebago is the deepest lake wholly contained within the entire New England region, although some sources say that Vermont's Lake Willoughby is slightly deeper. Along with Lake Champlain, Sebago is one of the only lakes in the area that does not consistently freeze solid during the winter months, with total ice cover only occurring for a short period of time every few winters. Sebago covers about 45 square miles (117 km2) in surface area, has a length of 14 miles (23 km) and has a shoreline length of roughly 105 miles (169 km). The surface is around 270 feet (82 m) above sea level, so the deep bottom is below the present sea level. It is in Cumberland County, and bordered by the towns of Casco, Naples, Raymond, Sebago, Standish and Windham. The seasonally occupied town of Frye Island is on an island in the lake. Sebago Lake and the surrounding area is known for its erratic and sudden changes in weather during all seasons, likely due to its proximity to the Atlantic Ocean and to Mt. Washington, a very notorious extreme weather hotspot. The name comes from the Abenaki sobagoo, meaning "it is the sea" or "it resembles the sea".

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.

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.

The Muddy River is a 5.3-mile-long (8.5 km) tributary of Sebago Lake in the U.S. state of Maine.

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 Dyke Mountain Annex is a historic house at 319 Dyke Mountain Road in Sebago, Maine. This 2+1⁄2-story wood-frame house was built sometime between 1906 and 1908 by Grace L. Dike, proprietor of the Dyke Mountain Hotel, a popular summer resort in the hills west of Sebago Lake. It is the only surviving element of the hostelry, the rest of which was destroyed by fire in 1927. This structure originally housed only sleeping and common lounge spaces, but was modified after the fire to have a kitchen, and continued to be operated as a summer hostel by Dike until her death in 1937. It continues to be used as a guest lodging facility by its present owners.The house is a 2+1⁄2-story wood-frame structure with a gable roof. An engaged porch wraps around three sides of the building, and the front roof facade is pierced by three shed-roof dormers. The second floor of the front elevation has five sash windows, while the first floor has an asymmetrical recessed face with its entry slightly less recessed than the surrounding exterior walls. The porch, under the overhanging second floor, is supported by chamfered square posts. The kitchen ell is a two-story structure extending to the rear of the main block. The interior of the first floor main block is one large chamber, accessed via doors from a vestibule area, with a stairwell in the southwest and a narrow hall leading to a bathroom and kitchen. There are four bedrooms on the second floor, and two more in the attic space.The house was listed on the National Register of Historic Places in 2005.

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.
