May 18 (Reuters) - Eight Louisiana refineries continued operating on Tuesday as the risk of flooding along the Mississippi River was reduced by the U.S. Army Corps of Engineers release of flood waters through the Morganza Spillway into the Atchafalaya River Basin.
The one refinery along the Atchafalaya, Alon USA Energy's ALJ.N 80,000 barrel-per-day (bpd) in Krotz Springs, Louisiana, said it expected to continue operating.
Exxon Mobil Corp's (XOM.N) 504,500-bpd Baton Rouge refinery, the nation's second largest, shut its docks on the Mississippi River as of Saturday. The refiner continued to operate, the company said. Sources have told Reuters production was down to at least 450,000 bpd due to tight crude supplies.
Scores of U.S. heartland rivers from the Dakotas to Ohio have flooded following a snowy winter and heavy spring rains, feeding near-record crests on the lower Mississippi River.
There are 10 refineries located along the Mississippi River which can process 2.4 million barrels per day of oil, or 13.7 percent of the country's refining capacity.

Magellan Midstream Partners (MMP.N) said operations would restart at its 2.8 million-barrel storage terminal in Marrero, Louisiana. Magellan's 50,000-barrel storage terminal in Gibson, Louisiana, remained shut. Water levels have crested at Marrero on the Mississippi, while water levels were rising on the Atchafalaya at Gibson.
Exxon Mobil (XOM.N) Pipeline Co has shut two 12-inch (30.5-cm) crude line segments of the North Line system north of Baton Rouge and one 16-inch segment of the Southwest line across the river from Baton Rouge. The lines were filled with water and will remain so until flooding ends.
The Mississippi River reopened at Natchez, Mississippi, on Tuesday. Travel through a 15-mile (24-km) stretch of the river near Natchez was restricted. Fifteen vessels were waiting to transit that section of the river on Wednesday, the U.S. Coast Guard said. That portion of the river may be closed if the river level at Natchez reaches 62.5 feet (19.05 meters). [ID:nN17181374]
Barge traffic is moving along the Mississippi River with some restrictions. Barges were running near Baton Rouge, but facing difficult river conditions.
