This is a 20 yr old community pond and it's about 10 acres. When we get a lot of rain the pond floods pretty badly, putting the fixed parts of the dock/gazebo, my fish feeders and much of the shoreline trail I built under water.
I was not around when the pond was built so I'm not sure who decided to build it this way, but common sense tells me that the reason the water gets so high is at least in part because the riser has this solid steel cover on it as opposed to more of a grate / rebar construction that would allow a lot more water to drain. The holes around the top of the riser, in conjunction with the spillway, have not been adequate to prevent this flooding. This happens a few times every year.
Wondering if this was done to minimize strain on the riser to reduce risk of failure.
Is there an expert on here with experience building ponds / risers? I would like to petition the other owners to replace this solid cover with a design that would allow a lot more water to drain but I need some ammunition.
Any advice or resources would be most appreciated.
See attached picture of existing and of a design that would allow for a lot more drainage.
