Flood of June and July 2007

• The Corps cannot control floods, we can only
  respond to the flood by managing the outflows
  from our projects.

10
Flood OperationIndividual Project

• The goal of any flood damage risk reduction
  operation is to not exceed the downstream
  bankfull capacity.
• Releases from the lake, when combined with
  downstream runoff will not cause the river to
  exceed bankfull capacity, if possible.
• Flood waters will be stored as long as possible
  in order to accomplish this goal.

11
System Water Control Plan

• All the Lakes in the Red River Basin are Operated
  as a System
• Each river system has a system water control
  plan.
• Each system water control plan attempts to
  balance the percent of flood storage contained in
  individual project flood pools.

Why a Successful Flood Operation?

• Great Decisions by COE Districts HH Staff
• Very Accurate Forecasts by COE and RFC
• USGS - Measured Flows Kept Gages Working
• Great Work by the Lake Managers and Staff
• Excellent Communications and Coordination
• Timing of Release Reductions were Staggered
• It Stopped Raining Just in Time!!!
