Amistad Reservoir Boating, Water & Navigation
Plan boating on Amistad Reservoir with lake-level, navigation, invasive-species and safety context.
Before you launch
Water level, navigation and invasive-species rules matter.
Amistad can fluctuate 5–10 feet in a typical year and has historically fallen much farther below conservation pool, so current ramp and shoreline conditions are essential trip inputs.
TPWD posts invasive-mussel guidance for the reservoir; check current clean-drain-dry requirements before moving gear.
The reservoir crosses the U.S.-Mexico boundary, so anglers need to understand where they are fishing and which license applies.
Rocky points and steep dropoffs create excellent fish habitat while also making contour awareness useful for navigation and fishing.
