The Mermentau River continues to rise to historical levels in response to the flooding rains last week. Flood water levels across portions Acadia Parish have begun to slowly recede while the water funnels southward through the Mermentau Basin and the river.
The river gauge at Mermentau had risen to 10.4ft late Monday afternoon with a revised crest of 11.0ft expected Thursday by the National Weather Service.
If the river crests at expected levels, it would surpass the reading of 10.97ft that followed after Hurricane Juan in 1985.
The top 10 gauge readings at Mermentau are as follows:
1) 14.50 ft on 08/07/1940
(2) 13.36 ft on 05/23/1953
(3) 11.06 ft on 02/10/1955
(4) 10.97 ft on 11/02/1985
(5) 9.47 ft on 12/10/1972
(6) 9.05 ft on 04/25/1977
(7) 8.96 ft on 05/18/2004
(8) 8.66 ft on 06/02/1941
(9) 8.56 ft on 05/20/1980
(10) 8.54 ft on 04/18/1967
Additional data along with the latest readings can be found in the link above.
Basin-wide (across much of Acadia Parish) 10-13" of rain fell last week, most of it coming within 24 hours or less on January 10th.
North winds and drier weather later this week will allow for flood waters to slowly recede this weekend.
