Deteriorating overflow pipe - 04/22/19 01:28 AM
Hey folks, new guy here.
I just moved into a property with an awesome 6 acre pond, fed by at least 5+ underground springs. I've been told the pond was built back in the 1950's and the deep side with a hillside dam is around 50 ft deep.
There is an overflow pipe (18" (maybe 20?) galvanized) and it sits about 30-40ft from shore. I think it's a bit unique in that it runs straight down, and then come out 90 degrees outside of the dam wall. The overflow feeds a small creak, which hits the river about 1/4" mile away. The flow is always steady, probably a few gallons a second.
The issue is that I don't know the condition of the pipe, other than the top is rusting and and I can break small chips off with my fingers. I feel like I'm sitting on a time-bomb, a log (beavers) or loose boat floats into it from a strong wind.
I'm thinking an option may be to create a new overflow, built into a low corner of the dam, and possibly filling the old overflow pipe with concrete, but it's just an idea. I really need to a professional to get some advice, but not sure where to begin. One friend today suggested I need to talk to a civil engineer. Is that the best place to start?
Suggestions/Advice?
Thanks!
