Lewis and Clark Lake Boundary Survey

near Yankton, South Dakota

Lewis and Clark Lake is the most-downstream reservoir on the Missouri River – it is formed by the US Army Corps of Engineers’ Gavins Point Dam. The Omaha District of the US Army Corps of Engineers had knowledge that data from a 1971 boundary survey of Lewis and Clark Lake had critical discrepancies. The Omaha District contracted Eisenbraun and Associates to conduct research and provide a boundary re-survey of the flawed previous survey. Steep terrain, heavy tree cover and difficult weather conditions would need to be overcome to complete this resurvey. Eisenbraun and Associates crews researched and surveyed adjacent subdivisions to determine where gaps and overlaps existed along the Government boundary throughout three sections along Lewis and Clark Lake in Knox County, Nebraska. A replat to correct the former problems was prepared and filed at the completion of the field survey. The final delivery included a copy of the final filed plat, an Intergraph DGN file and tabular listing of found and set corners in state plane coordinates (NAD 83). E/A also provided a detailed analysis of the problem areas found in the survey.
