OHIO RIVER FLOOD THREAT RAISED TO 'MODERATE'. THE OHIO RIVER IS UNDER A FLOOD WARNING UNTIL SATURDAY AFTERNOON, AND IF THE FORECAST HOLDS, THE RIVER COULD REACH WATER LEVELS IT HASN'T HIT SINCE 2011.

OHIO RIVER AT CINCINNATI- WATER LEVELS

CINCINNATI, OHIO

Projections for the Ohio River's max crest rose more than a foot on Friday.
The National Weather Service originally predicted a max crest of 55 feet Thursday, but this was changed around 11:15 a.m. to 56.3 feet and to 56.5 feet around 2:15 p.m.

This caused the National Weather Service to upgrade a forecast of minor flooding to moderate.

Moderate flooding occurs when the river stage reaches higher than 56 feet.
The stage was measured at 53.07 feet at 3 p.m. This puts the Ohio River past the flood stage of 52 feet and the weather service said that minor flooding has already occurred.

The weather service also issued a flood watch for the entire region and predicted up to 2 inches of consistent, heavy rain by Sunday morning.

If predictions hold, the river could reach water levels it hasn't hit since 2011.
"We're looking at all of this recent rainfall and a very saturated ground and now a good soaking amount of rainfall is moving in," said Mike Kurz, a meteorologist from the National Weather Service in Wilmington. "All of that is going to turn into a significant amount of runoff."

If the river reaches 56 feet, this would be the highest the stage has risen since 2011 when the river peaked at 55.89 feet on March 13, Kurz said.

Officials closed floodgates in Queensgate Thursday evening in preparation for the weekend.

They haven't done that since 2011, said Jeff Oxenham, a senior engineer for the Metropolitan Sewer District.

But closing the floodgates on Carr Street between Mehring Way and W. 6th Street is a requirement to keep the area from flooding when the river rises above 55.5 inches.

"These floodgates protect a lot of business in Queensgate here," Oxenham said. "We're being a little cautious, but this is not something we can afford a mistake on."
Crews spent about four hours closing the gates on Carr Street Thursday evening.
"We're looking at technology from the '40s here," Oxenham said. "It works, but it doesn't close as fast as some of the more modern gates."

The mile-and-a-half floodwall along the Mill Creek Valley was put up in the 1940s, but not quite in time to help protect the city from the flood of 1937 -- when the Ohio River crested at a record 79.9 feet.

Additional floodgates along the wall can be closed if the river is projected to reach higher levels. Oxenham said the next gate (that likely won't be closed this weekend) is on Mehring Way and only closes when the Ohio River reaches more than 57 feet.

The gates will remain closed through at least Monday, according the Metropolitan Sewer District.

Last weekend, a number of river-bordering areas and streets were underwater after last week's snow melt and rains -- parts of Cincinnati's Coney Island were flooded; Kellogg Avenue was closed near the Riverbend Music Center; and Campbell County was forced to close several local roads.

The weather service warned that roads near the river will flood again along with parts of Anderson Township, the East End and California near the river. Sections along Ohio 52 in Hamilton and Clermont counties were also listed in danger.
The river is expected to remain above the flood stage until Monday.
