12 acre lake damage via flash flood - 04/20/13 03:53 AM
I am fortunate to say i still have a lake.
thanks to heavy clay/rock mix soil used on our dam.
While out of town, we recieved a very large amount of rain couple days ago. came back today and noticed my lake down 3 ft.
This corrigated metal culvert around 30", is connected to a larger horizontal culvert pipe.
the horizonatal pipe has been starting to rust out the past year.
We were in the process of designing a concrete spillway, but this happened 1st.
I have a emergency spillway, that worked. but the clay/dirt around this pipe must have gotten washed out from a leak.( im guessing) Now we are going to siphon down 4-5 ft in order to let this dry out so we can replan and give us some time in case it rains again.
Its still pretty unstable, so i place some plastic/rocks over where the water is entering to this hole. it stopped it from washing out even more, and is just draining at the moment.
if this drys out soon, could i pack more heavy clay into this to seal it off. ?
thanks
Don
