How do I get rid of silt in my lake or pond?

There are a lot of products that claim to get rid of silt or muck from the bottom of your lake or pond.  Some products attempt to resuspend the silt.  Some attempt to re-aerate the silt.  Some products try to decompose it.  However, most silt removal is very limited with these techniques.  Dredging is a proven solution to removing silt from your lake or pond.  Dredging can be done by digging the silt out or pumping the silt from the lake or pond.
