Context paragraphs:
Calumet Region: The Calumet Region is the name given to the geographic areas drained by the Grand Calumet River and the Little Calumet River of northeastern Illinois and northwestern Indiana in the United States.  It is part of the Great Lakes Basin, which eventually reaches the Atlantic Ocean.  This region includes the northern parts of Lake and Porter counties and the western portion of La Porte county in Indiana, as well as the eastern counties of northern Illinois, Will and Cook.  Since much of this region is on the south shore of Lake Michigan, it is sometimes referred to as the "South Shore".  Because it was initially cut off from the rest of the state due to natural geographic barriers like the Kankakee Marsh to the south, the Calumet Region was the last-settled portion of Indiana.  It is a sub-region of the greater Northwest Indiana region and the even larger Great Lakes region.

Crystal Lake (Gilmanton, New Hampshire): Crystal Lake is a 455 acre water body located in Belknap County in the Lakes Region of central New Hampshire, United States, in the town of Gilmanton.  Crystal Lake is at the head of the Suncook River watershed.  Water flows into Crystal Lake from the Belknap Range through Manning and Sunset lakes to the north.  Water from Manning Lake enters Crystal Lake via Nelson Brook.  Other waterways flowing into Crystal Lake include Wasson Brook and Mill Brook.  Water flows out of a dam from the southern end of Crystal Lake via the Suncook Lakes and Suncook River to the Merrimack River.  Shoreline development along Crystal Lake consists primarily of summer cottages, with a few year-round residents.  Belknap Mountain and Mount Major can be seen from the shoreline.

Badin Lake: Badin Lake is one of a series of lakes created by the damming of the Yadkin-Pee Dee River in the Uwharrie Lakes Region of the United States.  The Badin Lake Dam was built in 1917 to support a local aluminum smelting plant (Alcoa), and the associated community of Badin was named for the founder, Adrien Badin.  The power generation unit was sold to Cube Hydro Carolinas in February 2017.  Badin Lake is in the Piedmont area of North Carolina.  It is contained by Narrows Dam at the town of Badin, North Carolina.  Sitting within a valley, the lake is very deep, with a maximum depth of 190 ft (58 m).  The lake occupies 5350 acre and has 115 mi (185 km) of shoreline.  Its waters have an average summer temperature of 84.4 °F (29.1 °C) and an average winter temperature of 50.6 °F (10.3 °C).  No ferries cross Badin Lake.  The northernmost point of Morrow Mountain State Park is roughly 2 mi downstream from Narrows Dam.  The lake lies within Stanly, Davidson, Montgomery, and Rowan counties.  Much of the lake's eastern shoreline lies within the Uwharrie National Forest.

Washington (state): Washington ( ), officially the State of Washington, is a state in the Pacific Northwest region of the United States.  Named after George Washington, the first President of the United States, the state was made out of the western part of the Washington Territory, which had been ceded by Britain in 1846 in accordance with the Oregon Treaty in the settlement of the Oregon boundary dispute.  It was admitted to the Union as the 42nd state in 1889.  Olympia is the state capital.  Washington is sometimes referred to as Washington State to distinguish it from Washington, D.C., the capital of the U.S., which is often shortened to Washington.

Lake Region State College: Lake Region State College (LRSC) is a two-year public college in Devils Lake, North Dakota, United States.  It was founded in 1941 as an extension of the public school system and first known as Devils Lake Junior College and Business School.  Several name changes have occurred over the years ranging from Lake Region Junior College to Community College.  The current name of Lake Region State College was adopted in 1999.  From 1987 until 1999, the college was a branch campus of the University of North Dakota in Grand Forks, known as UND-Lake Region.  In 1984, the college became a part of the North Dakota University System.

Pickerel Lake (South Dakota): Pickerel Lake is a 955-acre spring-fed lake located in Day County, South Dakota, United States.  Pickerel Lake is part of the Glacial Lakes Region that encompasses much of Northeast South Dakota and stretches along the Coteau des Prairies hills.  The area was formed thousands of years ago by glacial activity.  Many of the depressions left behind were filled by melting glaciers.  This area is also referred to as the Prairie Pothole Region.  Pickerel Lake is one of the deepest natural lakes in South Dakota.  The name originated from an American Indian name meaning "where you spear long fish."  Excursion boats were common until the early 1900s.  A fish hatchery was built in 1929 and abandoned in 1979, when a new facility was built at Blue Dog Lake.

Packwood Lake: Packwood Lake is a freshwater lake in the Gifford Pinchot National Forest in the Cascade Mountains of Washington.  It is located near the town of Packwood and is a popular day hiking and overnight camping area.  The southern half of the lake lies within the Goat Rocks Wilderness area.

Maple Lake (Polk County): Maple Lake is a lake in central Polk County, Minnesota, United States, located 2 mi due south of Mentor and approximately 4 mi west of Erskine.  The name of the lake is taken from the extensive sugar maple tree forest which surrounds it.  Even before American settlement of the region, the existence of these extensive hardwood forests in an otherwise treeless open prairie gave the lake a geographic identity.  Maple Lake is a natural lake, and is the westernmost significant lake in the Red River Valley of Northwestern Minnesota.  The lake appears on 19th century historic maps of the area, and developed as a summer home and resort community as early as 1910.  As a result of drought conditions and low inflows during the 1930s, however, the lake nearly dried up.  Beginning in 1940 a two-stage Works Progress Administration development project involving the diversion of water from nearby Badger Lake and the Poplar River raised the lake to its current artificially maintained water level.  This rejuvenated the resort industry, and the lake remains a popular summer home, recreational watersports and fishing lake, drawing people from eastern North Dakota and northwestern Minnesota as well as other neighboring states.

Newfound Lake: Newfound Lake is located in Grafton County, New Hampshire, United States.  It is situated in the Lakes Region of central New Hampshire, in the towns of Alexandria, Bridgewater, Bristol, and Hebron.  Its area of 4451 acre places it behind only Lake Winnipesaukee and Squam Lake among lakes located entirely within New Hampshire, and fourth in the state overall, when Umbagog Lake on the Maine border is included.  Newfound Lake is refreshed twice a year by eight underground springs and has 22 mi of shore line.  The lake is about 2.5 mi wide and 6 mi long.  The deepest point is 183 ft .  Major tributaries include the Fowler River and the Cockermouth River.  Its outlet is the Newfound River, flowing through Bristol village into the Pemigewasset River.  The lake volume is 98 billion gallons of water.
