pond bank erosion

pond bank erosion

(OP)
I have a one acre pond in NJ that is about 10 feet deep in the middle. It was built in 1960 and has a large earthen dam along one side. I've noticed increased erosion of the pond bank and I'd like to control it. It primarily occurs around tree roots of trees that are growing on the edge. There is also signs of animal borings in the pond bank.

What is the best way to arrest this erosion? Would rock or some kind of mat work to preserve the soil on the banks? During the winter, the vegetation dies back leaving the banks exposed to wind and wave action.

Any advise would be appreciated.

RE: pond bank erosion

It sounds like a problem of Mother Nature returning things back to where they were. You can take many steps at great expense to preserve the effects and appearance of the pond, but it will be an ongoing expense.

Don't have a lot of choice.  I need keep the pond intact.  What would you recommend to mitigate erosion?

RE: pond bank erosion

Presto Geosystems makes a product called Geoweb that's commonly used for slope and shoreline protection.

This doesn't sound like a DIY type of project however.  Contact a local geotech firm after doing some homework on your product options for stabilizing the slope.  If you implement a fix that doesn't work, it will cost you more $ and frustration in the long run.  Spend some bucks and get it right the first time.  Best of luck.

RE: pond bank erosion

remove the trees, trap the varmints, place some geotextile and use riprap or broken concrete at the shoreline.

fair warning, if you haven't maintained the dam or pond (and have records of such maintenance) you may be doing work in jurisdicational waters and wetlands and require a permit to work at the water's edge.  No kiddin' even if it's your own property.
