when i lived in northern LA not too long ago, i did ALOT of fishing on this lake with a well known member of this site. I cant begin to praise this lake enough. it is BY FAR one of the best (if not THE best) crappie lake in the state of louisiana, and i have fished alot of them. where you may not always get the numbers you can find at spots like darbonne, cypress, and bist., the size and quality of the fish was always head and shoulders above the rest. all my success came on the south-eastern part of the lake, about 3/4's of the way to the dam, in deep water. I helped plant several bamboo tree's out there, and so have several other people, judging from the sonar. one of my fondest memories of fishing that lake came from a mid winter trip with two friends of mine. we put a LOAD of crappie in the boat that day, as our buddy percher can attest to. there were several times throughout the day with all 3 of us were landing fish simultaneously.
if you have the time, and the means, do yourself a favor: get thee to the Grand Bayou!
