Davenport Public Works employees will begin moving floodwall sections into place at Modern Woodmen Park today in preparation for a higher-than-forecast crest.

The National Weather Service forecast the Mississippi River to crest at 15.7 feet on Sunday at Lock and Dam 15, but 3 to 4 inches of rain is expected Wednesday through Friday.

The river already is lapping at South Concord Street.

"The runoff will hit at the same time as the already-forecast crest," Davenport Public Works director Mike Clarke said Tuesday. "That will raise the crest and lengthen it."

National Weather Service meteorologist Tom Philip said the crest forecast for Sunday is based on rainfall amounts through 7 a.m. today. How much higher the crest will go depends on how much rain actually falls, he said.

Public works and police have been closely following flood levels since they reached 10 feet and are talking to the National Weather Service regularly. Clarke declined to say what crest level the city is are planning for. A flood planning meeting is scheduled for this morning.

The city's flood planning calls for flood protection 1 1/2- to 2-feet higher than the forecast crest. City workers have prepositioned pumps and also checked pumps in the Garden Addition as well as storm sewer valves that are closed to prevent backflow with high water.

"We will weather this flood with the same efficiency we weathered the last three floods that were in the top 10 in the area's history," Clarke said.

At 15.7 feet, water will begin lapping into LeClaire Park, and at 16 feet, Credit Island Lane is affected. Moline's River Drive also is affected.

The forecast calls for heavy rain through today and during the daylight hours Thursday. Rain chances diminish to 60 percent Thursday night. There is a 70 percent chance of a rain and snow mix Friday during the daylight hours. Snow is likely before 1 p.m.

The high today is expected to hit 55 degrees, while the high Thursday is expected to reach 60.

Friday’s high should reach only into the low to middle 40s.

Friday night, the clouds begin to leave and the mercury is expected to drop to an overnight low of 29 degrees.

Saturday’s forecast calls for mostly sunny skies and a high of 51 degrees.

The City Council, the RDA and the rest may be pretty much worthless but at least we have one part of City Government run by an extremely competent man. His performance during these floods so far has been outstanding and then some.

As long as the Mayor and the City Council gives him the tools he needs he'll get the job done ... again
