The PLSS has been expanded and slightly modified by Letters of Instruction and Manuals of Instruction, issued by the General Land Office and the Bureau of Land Management and continues in use in most of the states west of Pennsylvania, south to Florida, Alabama, and Mississippi, west to the Pacific Ocean, and north into the Arctic in Alaska. With little power to tax, the federal government decided to use the sale of the Western Territories to pay off war debt. The Confederation Congress was deeply in debt following the Declaration of Independence. The Land Ordinance of 1785 marks the beginning of the Public Land Survey System. Before this could happen, the land needed to be surveyed. The government wished both to distribute land to Revolutionary War soldiers in reward for their services and to sell land as a way of raising money for the nation. Originally proposed by Thomas Jefferson to create a nation of ' yeoman farmers', the PLSS began shortly after the American Revolutionary War, when the federal government became responsible for large areas of land west of the original thirteen states.

Monument referencing the beginning point of the PLSS Today, the BLM controls the survey, sale, and settling of lands acquired by the United States.

The Surveyor General was later merged with the General Land Office, which later became a part of the U.S. Following the passage of the Northwest Ordinance in 1787, the Surveyor General of the Northwest Territory platted lands in the Northwest Territory. Beginning with the Seven Ranges in present-day Ohio, the PLSS has been used as the primary survey method in the United States. Also known as the Rectangular Survey System, it was created by the Land Ordinance of 1785 to survey land ceded to the United States by the Treaty of Paris in 1783, following the end of the American Revolution. The Public Land Survey System ( PLSS) is the surveying method developed and used in the United States to plat, or divide, real property for sale and settling. It can also be called a horseshoe lake, a loop lake, or a cutoff lake.This 1988 BLM map depicts the principal meridians and baselines used for surveying states (colored) in the Public Land Survey System. An oxbow lake gets its name from the U-shaped collar placed around an ox's neck to which a plow is attached. These lakes eventually dried up to create acres of land for farming, housing, and industry. The Mississippi River is shorter now than it was in the 19th century, for instance, because engineers have cut off hundreds of meanders. Giant river otters ( Pteronura brasiliensis) frequently live in the Amazons oxbow lakes, and feed on about five kilograms (11 pounds) of fish per day. Along the Amazon River in South America, oxbow lakes are common and their still waters provide a unique habitat for plants and wildlife.

Oxbow lakes can be rich wildlife habitats. Oxbow lakes often become swamps or bogs, and they often dry up as their water evaporates. There is no stream or spring feeding the lake, and it doesn't have a natural outlet. This means that water does not flow into or out of them. Oxbow lakes are the remains of the bend in the river. Erosion and deposition eventually cause a new channel to be cut through the small piece of land at the narrow end of the meander. Silt and sediment build up on convex banks. The banks opposite the concave banks are called convex banks. The force of the rivers flowing water wears away the land on the meanders concave banks. The corners of the curves closest to each other are called concave banks. Meanders that form oxbow lakes have two sets of curves: one curving away from the straight path of the river and one curving back. On these plains, rivers often have wide meanders. Oxbow lakes usually form in flat, low-lying plains close to where the river empties into another body of water. The meander becomes an oxbow lake along the side of the river. A lake forms as the river finds a different, shorter, course. An oxbow lake starts out as a curve, or meander, in a river.
