IOWA CITY (KWWL) -

More encouraging news came out of Johnson County Tuesday, as officials once again scaled back flooding predictions.

The Army Corps of Engineers is now predicting the Coralville Reservoir will crest at 709 feet Thursday, 3 feet below the emergency spillway.

The Corps also gave some insight on the length of time this flooding could last.

Officials are projecting that it could be June 12 before the flooding begins to subside.

The gates at the dam will likely remain open until next week as officials try to get the lake level down to a more manageable level.

Researchers at the Iowa Flood Center are saying the response to flooding has changed since 2008.

New technology allows officials to observe river flows and levels as they change in real time. The information results in more frequent river forecasts than ever before.

And while the news of the projected crest at the Coralville Reservoir continues to improve, researchers say the area still remains in a vulnerable state as long as the lake levels remain high.

"The tools that we have now and what we learned, is that we have to keep an eye on precipitation as it falls in as close to real time as we can, because we don't know where the next huge storm is going to land," said Ricardo Mantilla, a researcher with the Iowa Flood Center.

Researchers credit the Army Corps of Engineers for preventing more extreme flooding by being more aggressive than 2008.
