Aids maps makes one that has names of coves and other land marks but is very small so the detail stinks. You can also get a map from national park office but it is not the easiest to read as it is in meters and elevations instead of depths. The absolute best map that can be gotten for Amistad is the Navionics map chip, 2008 edition, for GPS systems. Amistad is in the West Texas/New Mexico section.
