What is the Duncan Canal?
The Duncan Canal is a man-made waterway. It helps control water levels in a big area of Louisiana. Think of it like a giant ditch built to move water from one place to another.
Why is the Duncan Canal Important?
The main job of the Duncan Canal is drainage. This means it collects extra water from rain and the ground. Without good drainage, areas in Louisiana could flood easily.
- Water Collection: A system of pumps and smaller canals brings rainwater and groundwater into the Duncan Canal. This water comes from the East Bank of Jefferson Parish.
- Water Movement: The canal then carries this water away. It drains into Lake Pontchartrain, a large lake nearby. This process helps prevent flooding in cities like Kenner, Louisiana. Kenner is located on the Jefferson Parish side of the canal.
Where is the Duncan Canal Located?
The canal forms a natural boundary. It separates Jefferson Parish from St. Charles Parish for a long distance.
- Jefferson Parish Side: The city of Kenner is on the Jefferson Parish side. This is also the eastern side of the canal.
- St. Charles Parish Side: Most of the area on the St. Charles Parish side is undeveloped swamp. This means it's a natural wetland with lots of trees and water.
How Does the Canal Protect the Land?
Along the Jefferson Parish side of the canal, there is a special structure.
- Levee and Flood Wall: A levee runs along this side. A levee is a raised bank built to prevent a river or canal from overflowing. On top of this levee, there is a strong concrete flood wall. This wall adds extra protection against high water. It helps keep the city safe from floods.
