25 At levels near 25 feet water is over the top of the dock at the Phillips Terminal near Sweeny with all vessel traffic stopped. Widespread inundation of the left flood plain occurs.
20 At levels near 20 feet major lowland flooding begins. Water is within 5 feet of the top of the dock at the Phillips Terminal near Sweeny. Tugs can not push barges upstream and are unable to dock and there is widespread innundation onf the flood plain.
17 At levels near 17 feet moderate lowland flooding begins. Water is over the mid level walkway at the Phillips Terminal near Sweeny. Barges can not push barges upstream and are unable to dock. Water begins spilling into the left flood plain.
16 At levels near 16 feet minor lowland flooding begins. Water is over the mid level walkway at the Phillips Terminal near Sweeny and tugs can not push barges upstream and are unable to dock.
14 Water is over the lowest platform at the Phillips Terminal near Sweeny. Shipping barges moving up the San Bernard River must fight the current and docking maneuvers are affected.
13 Water start spilling over the right bank and covers the lowest platform at the dock just upstream from the gage.
12 Caution stage, a strong north wind can cause barges scrape bottom.
