If you fish in the main river or anything on the Texas side no you don't need it. If you go in any cut/ditch/creek East of the river channel you will need a LA license.
100%....the Sabine River is not like Toledo Bend to where all you need is either a TX or La license and you are good no matter where you go. If you go into anything off the main river into La you will need a Louisiana license. Also, something else to consider, it used to be and I am almost positive that it still is a law, but anything south of Interstate 10 requires a saltwater stamp as well.
Good point! I never considered it because I always buy a super combo with every endorsement/stamp.
I took the below from the TPWD website. Anything East and South of these boundaries is considered saltwater.
