Photograph of detention reservoir; D.A - 490 acres. Permanent pool - 1.15" runoff with 10.0 acres surface. Flood pool - 4.56" runoff with 29.4 acres surface. Total storage 0 5.71" runoff from 490 acres. Flood pool (10' in depth) discharges through an 18" metal pipe at rate varying from 29 c.f.s. to 38 c.f.s. Both pools were empty but were filled during storm of May 9-10 and 1.0' depth.

Photograph of this 30 acre field of corn was damaged only about 10% during the storm of May 9-10 when 15.5 inchs of rain fell. Without the detention reservoir shown in the background the field would have been a total loss. The reservoir held 5.7 inches of runoff. The normal release, through a 18" pipe, may beseen in the small drain at the right of the corn field.
