Yep, Louisiana big bass are hard to catch. I should know, I have lived and fished here most of my life. There are a good number of 10 lb bass swimming in Toledo Bend and some other LA lakes....but it is nothing like Cali where a real good weekend trophy hunter can catch several a year, every year. Man, do I miss Cali bass fishing!
Toledo has put out more 10 lb plus bass this year than any other year in it's history, I believe. Of course, I have fished it only twice this spring, due to family and work. However, The Bend (as many locals call it) is notoriously tough on us big swimbait fishermen.
There are some other lakes in LA with big bass and better odds of catching them. Friday I had 25 lbs for 5 fish on one of them. PM me Rob and I'll hook you up.
I get my big bass fix by traveling to Texas. When I moved here from Cali in about 2005 I hit the Amistad boom. That was the best swimbait fishing I ever experienced, as far as getting bit a lot. It's beauty is up there with Bacarrac. Alas, Amistad went in the tank due to low water. But Falcon boomed next and what a boom it was, probably the best fishing overall I have ever seen. Now it is down and I have turned to Lake Fork (like I did in the 90's).
I caught a 23" post spawn fish there 3 weeks ago on a big swimbait. I'll make a couple of trips there each year. It is 5 1/2 hours from Lake Charles, where I live.
