The duration <br />of this storm was about eight hours and the precipitation <br />was estimated at 3". None of the ponds discharged during <br />this event but we had three breaches in the sediment control <br />ditches. The ditches have been repaired and are functioning <br />properly again. <br />We had several major blowouts in the contour furrows that <br />I will have to evaluate to make a decision on the method <br />of repairs. <br />As I informed you on the phone on Monday, August 30, 1993, <br />the previous storm was recorded at 1-3/4" in a two hour <br />period. As soon as I get confirmation on the severity of <br />this event I will let you know. <br />If you have any questions, <br />Sincerely, <br />~~ ~~ <br />Michael T.
