The Trinity River ends here in a delta of freshwater marsh grading into brackish and then salt marsh, and that gradient is what makes the area so productive — most of the shrimp, crab and finfish taken from Galveston Bay spend part of their lives in marsh like this. It is also a wintering ground for enormous numbers of snow and white-fronted geese. The delta is losing ground on two fronts: dams upstream hold back the sediment that used to rebuild it, and the land itself is subsiding.
