Weekend rainstorms lead to backwater flooding, road closures

Ascension Parish officials barricaded three roads in low-lying areas Monday and braced for more high water due to backwater flooding from the Amite River and Bayou Manchac, officials said.

The Amite River is expected to approach and even exceed flood stage late Monday and early Tuesday after heavy weekend rains, the National Weather Service reported Monday.

The Amite at Bayou Manchac is expected to surpass flood stage by one foot when it crests at 10 feet at midnight Monday.

Farther south, the river at Port Vincent is projected to crest at 5.9 feet at 6 a.m. Tuesday — more than 2 feet below flood stage, the Weather Service reported. Flood stage for the Amite at Port Vincent is 8 feet.

Parish crews put up barricades Monday at Airport Drive, Kay Drive and Idle Hour Road due to high water, parish officials said.

Airport Drive is off of Summerfield Road South and southeast of the La. 42/La. 431 intersection.

Kay Drive and Idle Hour Road both run north off La. 42 west of the La. 42/La. 933 intersection, parish officials said in a news release.

Some parts of northern Ascension Parish accumulated more than an inch of rain over the weekend, the Weather Service said. A gauge in Prairieville recorded 1.32 inches of rain from early Saturday to early Monday. But the heaviest rain in the Amite River Basin fell just north of Ascension in East Baton Rouge Parish.

Gauges on Claycut Bayou and Bayou Fountain recorded 2.14 and 1.98 inches, respectively. Claycut flows directly into the Amite while Bayou Fountain flows into Bayou Manchac, which flows into the Amite.

Assistant Department of Public Works Director Johnny Richardson said crews will continue to monitor roads along Manchac and the Amite.
