I purchased some property with a nearly an acre pond on it. The overflow pipe is pvc and about 10 inches. When I bought the place there was nothing over the end of the pipe. It was just open. No one had actively used the property for several years. I have fashioned a cover to keep large debris out but the flow out of the pipe is not enough to handle even a small rain... it goes over the emergency overflow. The exit pipe below the dam is 1/2 full or less. There doesn't seem to be as much flow as there was initially. Any ideas for unplugging this pipe?? I think there must be some debris in it. It may be 12 to 15 feet down and I don't know if there is a 90 angle down there or not. There has been some beaver activity(although at least one is not active any more). Any ideas suggestions would be appreciated.
Thanks,
Mike
