We lowered our lake and will be scraping and hauling off a lot of the sediment that is in it.
Would I have any issues with dumping this material,(Sediment, Muck, Dirt, Rock)on the backside of the dam ?

Should I scrape the brush and vegetation off the back before adding the material.?
We would like to make the backside of the dam with a more gentle slope so we can cut grass and maintain it.

thanks
