The Bonnet Carré Spillway is a flood control structure located in Louisiana, USA. It was built to manage excess water from the Mississippi River and protect nearby communities from flooding. The spillway can divert water into the Lake Pontchartrain basin, helping to reduce pressure on the river during high water events. Constructed in 1931, the spillway is an essential part of the region's flood management system. It features a series of gates that can be opened to allow water to flow into the spillway when river levels rise. This helps maintain safety and stability for the surrounding areas.
