I live in the area of that launch and those canals are only good for bream. If you run to the lake and fish the canals thqt feed in the lake you will have better luck there. I usually fish the Bayou Gauche and Des Allemands area and do really well all year long. If you want to go one day just contact me and I will let you follow me out there to show you a few spots.
