Summer field trip to the Caernarvon Freshwater Diversion
Our partners at the Lake Pontchartrain Basin Foundation and the National Wildlife Federation recently took out a group of folks to see the Caernarvon freshwater diversion and the new land it is building in Big Mar, 20 miles south of New Orleans. Participants were taken by airboat to the diversion structure itself, down the conveyance channel, and through the emerging delta in Big Mar. Caernarvon wasn’t designed to capture sand and other land-building materials out of the Mississippi River but rather to input freshwater into the basin in order to control salinities. Despite this, and its seldom operation and minimal flows, Caernarvon is building new land. That new land provides habitat for wildlife such as roseate spoonbills, alligators, catfish, osprey and turtles in addition to providing protection for communities from storm surge.
The tour included participants from Waggonner and Ball Architects, Trust for Public Land, the Link Restaurant Group, the Louisiana Public Health Institute, the New Orleans Redevelopment Authority and the Tulane Institute on Water Resources Law and Policy. See below for some pictures from this tour.
