ST. LOUIS COUNTY, Mo. – The Meramec River is expected to crest at 28.5 feet on Tuesday, posing a significant flood risk to areas around Eureka and Valley Park.
The river’s crest is predicted to be a foot and a half above the major flood stage mark of 27 feet. If the Meramec River reaches 27.5 feet, the Missouri Department of Transportation (MoDOT) warns that the northbound lanes of Highway 141 at I-44 may need to be closed for safety reasons.
In Eureka, floodwaters have already covered a section of Highway W near Twin River Road and multiple fields at Eureka High School. The parking lot at the high school is not expected to be impacted but Rockwood School officials are evaluating the situation.
Marshall Road, which runs behind the St. Louis Avenue floodgate in Valley Park, is now impassable in spots, further complicating travel in the area. The Vance Road floodgate near Valley Park High School is also at risk of closure. Officials have indicated that it could close as early as Monday afternoon, although they plan to reopen it as soon as water levels permit.
Residents in the affected areas are advised to stay informed about road closures and floodgate operations as the situation develops. Authorities are monitoring the river closely to ensure public safety.
