New Orleans Bonnet Carre' Spillway - Monitoring Locations

View the 2011 Bonnet Carre' Spillway and Morganza Floodway Viewer.

On April 11, 2008, the Bonnet Carre’ Spillway was partially opened as required by law to reduce the risk of flooding in south Louisiana by the Mississippi River. The diversion of freshwater into Lake Pontchartrain and adjacent waters will temporarily change the hydrology of the estuary. To better understand and qualify the water quality changes and effect on fishery resources and endangered species, Federal and state agencies and non-governmental organizations are monitoring events and collecting data.
