An example of a banco, created when a meander is cut off by a new, shorter channel, leaving a cut-off section of land surrounded by a U-shaped (oxbow) lake
The Banco Convention of 1905 between the United States and Mexico allowed, in the event of sudden changes in the course of the Rio Grande (as by flooding), for the border to be altered to follow the new course.[557] The sudden changes often created bancos (land surrounded by bends in the river that became segregated from either country by a cutoff, often due to rapid accretion or avulsion of the alluvial channel), especially in the Lower Rio Grande Valley. When these bancos are created, the International Boundary and Water Commission investigates if land previously belonging to the United States or Mexico is to be considered on the other side of the border.[558] In all cases of these adjustments along the Rio Grande under the 1905 convention, which occurred on 37 different dates from 1910 to 1976, the transferred land was minuscule (ranging from 1-acre (4,000m2) to 646 acres (261ha)) and uninhabited.[559][560][561]
↑Even though there were borders drawn as far as the Mississippi River, the early United States was only settled along the east coast. As the states were surveyed, these lines were solidified, though often missing their intended mark. By the time the country was surveying its western acquisitions in the mid-19th century, the process had improved and was being conducted through the United States General Land Office; the western borders were rarely controversial. Border surveys are given their own entry in this list if they were performed east of the Mississippi River, involved legislation, or were otherwise notable; the rest are detailed in footnotes in the relevant statehood or cession entries.

↑The treaty established the boundaries of the new country, from the Bay of Fundy: up the "St. Croix River" (which river this referred to was disputed) to its source; north to the height of the land (the "Northwest Angle of Nova Scotia"); along the height of the land to the "northwesternmost Head" of the Connecticut River (which source this referred to was disputed); down that to 45° north; west to the St. Lawrence River; up that to the Great Lakes, through Lake Ontario, the Niagara River, Lake Erie, the Detroit River, Lake St. Clair, the St. Clair River, Lake Huron, and Lake Superior; to "Long Lake" (which lake this referred to was disputed) towards the Lake of the Woods; to the northwest angle of the Lake of the Woods; then west to the Mississippi River. However, the Lake of the Woods was north of the source of the Mississippi River; maps universally show this undefined boundary as a straight line, nearly straight south, between the two points. From there, it followed the Mississippi River down to 31° north; east to the Chattahoochee River; down that to the confluence of the Chattahoochee and Flint rivers; a line from there to the source of the St. Mary's River; then down that to the Atlantic Ocean.[H]
