The chocolate colored water in Galveston Bay is more an issue of geography than pollution. Think sediment. Sediment does not equal man made pollution.
Galveston Bay is not a good poster child for what oil spills can do. It self corrects very well and has vastly improved over the last 40 years in spite of an increase in oil spills (which may be due to better detection rather than a real increase in spills). Much of the pollution was run-off related, so the issue was not even close to just oil. Pesticides and sewage had a lot to do with the problems, too. But the same mechanisms that dump all the pollutants (and sediment) there also clear them out. Particularly once the upstream sources clean up. Weekly fish kills of the 80s don't happen any more. You don't see oil slicks floating in and out with tides any more. Galveston Bay is not without issues, but look at the trends.
SOB
Houston Ship Channel, however, is nasty...too much like a pond to self correct. But even it has shown some improvement.
These improvements are not due to decreasing oil production in the Gulf of Mexico. Oil production in the Gulf peaked in 2002 when the state of bay report at that URL was released.
