Went fishing at Grand Bayou Lake just outside Coushatta yesterday. I caught over 20 bass in a span of about three hours. I also caught enough big Mason bream to have a couple of fish frys with. The reason I switched from bream to bass was the fact that bass kept blowing up on my slip cork. Switched to a Pop-R. Nothing like bass on topwater.
There is also a fantastic Farm/fresh produce/peaches stand just on the west side of the Red River bridge outside of Coushatta. It is on the way if you're coming from I-49 or Highway 1. I had a salad with homegrown lettuce/cukes, sweet onions with my fried fish last night.
I highly recommend that you try this lake out in the future. They have fantastic cabins for rent, they come with their own private dock and there is a real nice beach with amenities there. Here is the link to the resort. I'm calling today to reserve a cabin in September.
