Eagle Lake is the first, largest, and deepest lake of the Allagash Wilderness Waterway in the North Maine Woods. The lake covers the eastern side of Eagle Lake township. The southern end of the lake extends into Maine township 7, range 12, where it receives overflow from Indian Pond, and into Soper Mountain township where it receives overflow from Haymock Lake via Smith Brook. Other ponds in the Eagle Lake watershed include Woodman Pond via Woodman Brook, Pillsbury Pond and Little Pillsbury Pond via Smith Brook, Soper Pond and Upper Soper Pond via Soper Brook, and the Russell Ponds via Russell Brook. Eagle Lake originally received overflow from Chamberlain Lake, but Lock Dam has diverted most Chamberlain Lake overflow through Telos Cut to the Penobscot River since the 1850s.
Seboeis Lake extends from Lake View Plantation, Maine, north into Maine township 4, range 9. The lake is enclosed by rocky headlands and sandy beaches and contains several pine-covered islands. The inlet at the north end receives several tributaries from Long A township including Dean Brook, Jordan Brook, and West Seboeis Stream. Bear Brook flows into the northwest corner of the lake, and Northwest Pond overflows into the west side of the Lake. West Branch Sebois Stream overflows the east side of the lake through Dudley Rips into Endless Lake; and Endless Lake overflow reaches the Piscataquis River 15 miles (24 km) downstream, just 3 miles (4.8 km) upstream of the Piscataquis and Penobscot River confluence at Howland.
Schoodic Lake is a deep Maine lake with a small drainage basin. The lake covers much of the western half of Lake View Plantation. Tributaries drain Orson Bog, Norton Pond, and Jaquith Pond in eastern Brownville. The south end of the lake overflows through Schoodic Stream 5 miles (8.0 km) to the Piscataquis River 13 miles (21 km) upstream of the Piscataquis confluence with the Penobscot River at Howland. The lake provides good habitat for togue, squaretail, and land-locked Atlantic salmon. Fishermen also find smallmouth bass, white sucker and round whitefish.
Allagash Lake is in the North Maine Woods on the boundary of Maine range 14 townships 7 and 8. Allagash Stream flows into the northwest corner of the lake from Allagash Pond, Crescent Pond, and Mud Pond in township 9 range 15. Allagash Stream overflows the northeast corner of the lake and flows 5 miles (8.0 km) through Little Round Pond into Chamberlain Lake.

The Belgrade Lakes are a chain of lakes around Belgrade, Maine. The flow sequence is from East Pond to North Pond to Great Pond to Long Pond to Messalonskee Lake and thence via Messalonskee Stream to the Kennebec River at Waterville.

Millinocket Lake is the source of Millinocket Stream in the North Maine Woods north of Baxter State Park. Millinocket Stream flows 5.5 miles (8.9 km) to Maine township 8, range 8, where it joins Munsungan Stream to form the Aroostook River. The lake extending along the border of Maine range 9 townships 7 and 8 is impounded behind a wooden dam. The dam enlarged the lake to include Little Millinocket Lake and Moose Pond by flooding adjoining bogs to store water for hydropower. The large areas of shallow flooded bog are a good habitat for fallfish, yellow perch and white suckers; but with summer water temperatures ranging from 70° near the surface to 55° in the deeper areas, dissolved oxygen concentrations become unfavorable for trout. Tributaries to the lake drain a number of small ponds to the west of the lake including Atkins Pond, Blackmore Pond, Buckley Pond, Big Caribou Pond, Little Caribou Pond, Chandler Pond, Elsie Pond, Ervin Pond, Jack Pond, Kyle Pond, Line Pond, Mathews Pond, May Pond, Little Moose Pond, Upper Moose Pond, Pretty Pond, Snowshoe Pond, and Spring Pond.
Spencer Lake extends southward from Fish Pond in Hobbstown township into Maine township 3, range 5. The north end of the lake receives drainage from Whipple Bog, Whipple Pond, Hall Pond, Toby Pond, and Chub Pond through Fish Pond. The south end of the lake overflows through Little Spencer Stream and thence Spencer Stream 6 miles (9.7 km) to the Dead River 14 miles (23 km) upstream of the confluence with the Kennebec River at The Forks. The lake supports a native population of lake trout and brook trout, and has been stocked with land-locked Atlantic salmon. There is a boat launch area at the north end of the lake accessible from a 2-mile (3.2 km) gravel road 11 miles (18 km) west off U.S. Route 201 at Parlin Pond.

Toddy Pond is a long, narrow Maine lake with three basins. The southern basin extends from Blue Hill northward to the middle basin forming the boundary between Penobscot and Surry. The northern basin is in Orland, where US route 1 follows the shoreline of the northern tip of the pond. The north end of the pond overflows through Alamoosook Lake into the Orland River. The northern basin cold-water habitat has a self-sustaining population of lake trout, and is stocked with splake, brown trout, and land-locked Atlantic salmon. Smallmouth bass and white perch thrive in the warmer water of the middle and southern basins. The pond is used by a spring spawning fun of alewife. There is a public boat launching site off highway 1 at the north end of the pond.
Highland Lake extends from the northern tip of Westbrook through the western edge of Falmouth into east Windham, Maine.

The deeper northern basin of the lake in Windham has been stocked with brown trout, splake, alewife, and occasionally brook trout and land-locked Atlantic salmon. The shallow southern basin is favorable habitat for white perch and chain pickerel, and has been stocked with largemouth bass.
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.
Crescent Lake receives drainage from Coffee Pond and Dumpling Pond in northern Casco, Maine, and extends south into Raymond.

Smallmouth bass, largemouth bass, chain pickerel, and white perch thrive in the lake. Dissolved oxygen deficiency below the 11-metre (36 ft) summer thermocline limits suitability for cold-water fish; but the lake supports populations of cusk and rainbow smelt.
