I had a two acre pond constructed one year ago and the dam is about 750 feet long.

Within a few hours of finishing the dam it started to rain. We tried to seed the dam with rye grass but it kept washing away.

Now one year later we have a lot of silt in the new pond and severe erosion. Some of the gullies are two feet deep and the top soil we had is not on the bottom of the pond.

We have hired a contractor to repair the erosion but he is not interested or willing to get involved in stopping the erosion from returning.

The sides of the dam are quite steep and and due to a leak (since fixed) the depth of the pond is down to 5 feet from the typical 10 so we have even more of the sloop exposed going into the "rainy season here in East Texas.

I think I know how to repair the erosion but how do I stop it from returning?

Thanks in advance for your advice.
