re: What’s the best lake to buy a camp on in LA?

Do you want to be land locked ? There are several beautiful oxbow lakes and reservoirs mentioned here. They are all landlocked. If you want to be able to explore a lot of water and minimize boat traffic , there are only two choices

Toledo Bend
Lake Verret system

From a boat ride perspective , we have taken day trips from LV to New Iberia and Houma for lunch. Have also gone through the lock and south into the bays at the mouth of the Atchafalaya River to catch redfish in August. I plan to make a run this summer from the boat launch under the HWY 1 bridge in Port Allen, through the Sorrel lock and into Pierre Part Bay to the camp and back. It gets busy on the weekends, but there is enough water to find quiet place to fish, ski or ride.
