SHREVEPORT, LA (KSLA) -

Another week of active weather is expected across the ArkLaTex with heavy rain and strong to severe thunderstorms. On early Thursday morning, a shower soaked the area.

According to the National Weather Service, the Red River in Shreveport has begun to rise again, with a new crest listed at 31.5 feet by Sunday. Levels should hold steady by at least Tuesday.

In Coushatta, a new forecast crest is set at 34 feet. The river is at a moderate flood stage through Tuesday. In Grand Ecore, a new forecast sets the river below major flood stage. The river is expected to rise to 37.5 by Tuesday in a moderate flood stage.

Bayou Bodcau at Bayou Bodcau Lake continues to rise and will enter moderate flood stage by Saturday night. However, the lake is expected to continue to rise through Tuesday. 

Bayou Dorcheat at Lake Bistineau is still slowly rising and expected to crest on Sunday at major flood stage.

Caddo Lake will slowly rise and is expected to crest on Friday in minor flood stage. The Sabine River at the Toledo Bend Reservoir, slowly rising to 172.9, putting the river in action stage, according to NWS.

The Red River in Shreveport has crested early Wednesday morning and is going down, but the threat of rain will affect how quickly it goes down.

One water-way still reaching its peak is Lake Bistineau. 

Hwy 164 between Doyline and Sibley is closed for several miles near the lake. DOTD has the highway shut down because of the amount of water that is flowing across the road. 

Bossier Parish deputies surveyed the area and plan to stay out there as long as a flood threat is present since it is expected to reach major flood stage by next week.

Floodwaters have overtaken the Lake Bistineau spillway near Elm Grove in southern Bossier Parish.

The spillway gates remain closed for repair. But drawdown gates are in operation.

"There are no 'flood gates' at this structure, only drawdown gates, which lower water levels slowly over a period of time," Louisiana highway department spokeswoman Erin Buchanan said Monday afternoon.

The biggest flood threat from Tuesday's rain targets Natchitoches Parish. The Red River level at Grand Ecore sits just above 34-feet but is expected to crest between Wednesday night or Thursday morning at major flood stage.

Louisiana Gov. John Bel Edwards declared a state of emergency Monday for Bossier, Caddo, Natchitoches and seven other parishes.

The order adds nine parishes to a declaration made Thursday due to severe weather starting Wednesday in Grant Parish.

"... the state anticipates further assistance will be needed for parishes within the threatened emergency area in their response to this continuing threat of flooding as the rivers rise in response to the severe weather from February 21 to February 25," the amended declaration states.

Meanwhile, Red River at Shreveport reached flood stage early that morning, according to the National Weather Service.

At 5 a.m., the Weather Service measured the river at 30.05 feet in Shreveport, where the flood stage is at 30 feet.

Representatives of the Caddo Sheriff's Office held a briefing to update the public on flooding concerns at 8 a.m.

Weather Service forecasters say the river will rise to near 31 feet by Tuesday evening. It then will fall below flood stage by Thursday afternoon.

Several public boat launching ramps were closed along the Red River Friday afternoon due to rising water.

The Red River has also overtaken the boat launch and dog park at the eastern end of Stoner Avenue in Shreveport.

And the threat of 1-3" of rain Tuesday through Thursday morning will aggravate flooding, according to the National Weather Service.
