The US Army Corps of Engineers is mapping the bottom of a major river

The US Army Corps of Engineers awarded a contract to survey the Lower Monongahela River. This means a private company will use sonar and other tools to map the riverbed.

The Monongahela River is a major shipping route for coal and other goods in Pennsylvania. Detailed underwater surveys help the Army Corps of Engineers manage navigation, maintain dams, and plan for future infrastructure projects. This kind of data is essential for keeping commercial river traffic moving safely and efficiently.
