Heavy rains Monday created what looks like a stream on Birmingham Road. The road was closed due to the water and remained closed into Monday night.

"Get your boots out" is the warning for visitors to Uncertain as the rain continues to fall, pushing lake levels up.

"It's up six inches and rain is still coming down," said Billy Carter, owner of Johnson's Ranch Marina in Uncertain. "It's liable to be one of the good ones."

According to Karen Holzman, who works at the marina, their gauge showed Caddo Lake levels at 171.5 feet.

The National Weather Service's Advanced Hydrologic Prediction Service page on its Web site, showed Big Cypress Bayou in Caddo Lake at 171.05 feet at 8 a.m. Flood stage is 172 feet.

"The parking lots are covered, the docks are under water and the launch was still usable," she said around 11:45 a.m. Monday.

A flash flood warning for eastern Harrison County including Marshall as well as eastern Marion County, southeastern Cass County and parts of Louisiana had been issued as between four and five inches of rain fell Monday.

There were 19 roads that were closed or had water over the road Monday, with three becoming passable as of 8:30 p.m. Monday night.

The NWS, in its Hazardous Weather Outlook, noted numerous showers and thunderstorms are to be expected through at least Thursday, with Thursday's storms possibly severe in nature.

The NWS warns that the excessive runoff "will cause flooding of small creeks and streams and highway underpasses. Additionally, country roads and farmlands along the banks of creeks, streams and other low-lying areas are subject to flooding."

The NWS forecast for today is showers and possibly a thunderstorm with the high near 75 and a 100 percent chance of precipitation with east winds at five mph. The chance of precipitation tonight is lowered to 80 percent.The high is expected to be in the low 70s with east winds around five mph. For Wednesday, a 50 percent chance of rain is forecast with a high near 83 degrees and south winds at five mph.

"It's very unusual for flooding to come this time of year," said Carter, noting it was the fifth time in seven months that his property has flooded. "It's a really saturated piece of property down here."

At Caddo Lake, the boat ramp is closed and the water has reached the parking lots, said Park Manager Todd Dickinson.

"It's up into several of our campsites," he said, noting Mill Pond campground is covered three to five tent sites along the lake. "It will cover several more if it keeps raining."

Dickinson said because Caddo is a natural lake there is not a lot of give in its fluctuations. "It has a five to six vertical foot elevation change. If it is two feet below normal, we're drying up. If it is two feet above, we're flooding. There's not a lot of give," he explained.

Over in Uncertain, Carter said he has to wade out to his boats at present.

"It's time for everybody to get ready. Tyler Island may actually be an island again without motorized access. It could happen, it's getting close," he said.
