Charge to District Staff

• Establish MFLs District-wide for priority water
  bodies
• 5 year time-frame
• Best available data
• Focus initially on the Suwannee River
• Including springs

The Issue

• Loss of time-sequence by use of FDC
• Testing underway using HEC-RAS dynamic model to
  examine routing/channel storage/pickup effects
