Caernavon is only 17 miles southeast of New Orleans, but it looks totally different from most of the rest of the Delta. Here, trees are largely absent, and in their place are thousands of acres of gently waving marsh grass. Lake Lery is a popular open-water fishing area here, but many prefer to stay in the winding canals themselves. This region of the Delta has been enhanced by a special diversion canal that brings in water directly from the Mississippi, as well as by the stocking of fast-growing Florida bass. The river water has helped the spread of vegetation, which in turn has increased the habitat for forage.
Tides also influence much of the Delta fishing.
There is only one high and one low tide each day, but the water level may fluctuate two feet each time, especially in the lower part of the Delta. Another possible problem in fishing here is summer weather. It is hot and humid. The best fishing, by far, occurs in the spring and again in the fall. In the summer, some of the canals, especially in the Caernavon area, are totally choked with vegetation that makes boat navigation difficult.
