On March 9, 1973, at approximately 1326, the tank vessel TIV Mayo Lykes collided with the Bayou Lafousche Barge PC 2901. The bow of the TIV Mayo Lykes, penetrated the port bow of the barge at a 45-60 degree angle and almost cut the barge in two. Only the starboard outer skin of the barge held the vessel together. A large quantity of the 23,000 barrels of Louisiana crude oil and Bunker C spilled into the water upon impact. Heavy concentrations of oil impacted the beaches and water north to Morgan Point, east to the Houston Ship Channel, south to Clear Creek Channel, and west to the shores of upper Galveston Bay. Overall, approximately seven miles of tidal flats and beaches were contaminated as a result of the incident. High tides accompanied by strong south winds caused oil on the shore or trapped in bayous to contaminate areas above the normal tidal zone, as with Sylvan Beach in La Porte. Approximately 519,302 gallons of liquid pollutant, and 400 cubic yards of solid oil-soaked debris, were collected in the 28-day cleanup response.
