Ok found what I was looking for. Jugline fishing is allowed on Sabine but not on Lacassine.  
"Fishing is permitted with rod and reel 
or pole and line only on Cameron Prairie 
and Lacassine NWR’s. Sabine NWR 
permits jug fishing in designated areas in 
addition to rod and reel and pole and line 
fishing. See refuge specific regulations."
You  can read all about in here. It plainly states it on the first page.

The one who were jugging in the Duck Pond can also read this, but they were told about it already
