Early history (1841–56)

The United States Lakes Survey was created on 31 March 1841 by an act of Congress, appropriating $15,000 for a United States Army Corps of Topographical Engineers led survey of the Great Lakes. William G. Williams was appointed the first commander of the survey. He was assisted by Howard Stansbury, James H. Simpson, Joseph E. Johnston, Thomas J. Cram and I. Carle Woodruff. They were headquartered at the mouth of the Buffalo River. In the first summer, a detailed topographical survey of Mackinac Island was completed, reconnaissance surveys in the northern part of Lake Michigan were made and a site for a baseline near the entrance to Green Bay was selected and partly cleared.

The first four years of the survey largely dealt with the baseline at Green Bay, and building triangulation stations. Surveying work was additionally done on Lakes Michigan, St. Clair, and Erie, and at the Straits of Mackinac. To conduct hydrographic surveys, in 1843, an iron steamer named the Abert (after John James Abert) was built for the survey. Flaws in the ship's design were soon discovered, and it was overhauled and renamed Surveyor in early 1845. By the end of 1845, all harbors besides those in Lake Superior had been surveyed.

James Kearney replaced Williams in 1845, relocating the survey to Detroit. Work was temporarily halted for most of the Mexican–American War. After the war, work resumed and the west end of Lake Erie was completed in 1849. John N. Macomb took command of the lake survey in 1851. It greatly increased in size and appropriations. It published its first charts in 1852–covering all of Lake Erie. During the 1852–55 seasons, the areas surveyed by the Lake Survey included the Straits of Mackinac and the approaches 30 miles (48 km) to 40 miles (64 km) either side of Mackinac Island, part of the north end of Lake Michigan, all of the St. Marys River, and a few harbors on Lake Superior. As a result of this work the Lake Survey published three new charts. A second steamer, the Jefferson Davis (after Jefferson Davis) was launched in 1856, and soon renamed Search.
