• Levee Status Daily Reports

  • Federal Levee Daily Status - CAO 26 April 2012
  • Non-Federal Levee Daily Status - CAO 26 April 2012

  The freeboard estimates are based on overtopping stages determined by correlating levee elevations with river gage stage elevations. Top of levee elevations are from the National Levee Database.

• Lower flow scenario - Lower range of flows and stages represents approximately a 50 percent chance of being exceeded during the months of June, July and August.

• Higher flow scenario - Higher range of flows and stages represents approximately a 10 percent chance of being exceeded during the months of June, July and August.

• Levee Overtopping Projections Report - CAO 26 June 2011
  This report provides the probable range of levee freeboard based on the extended river stage predictions initially anticipated for the duration of the flood event.
