ANNOTATIONS TO
IOWA RIVER & CORALVILLE DAM INFORMATION
*Iowa River near Lone Tree: outflow trigger
Note that the Lone Tree threshold is NOT a typographical error.
The Corps goal for Lone Tree is to keep the water
at least one foot below flood stage at all times.
There is no documentation available from the Corps explaining
the rationale for how the values of any outflow triggers are set.
