Bottom Compostion Charts

[GLF]

I am looking for a chart that has the bottom composition of Lake Michigan. Does anyone know of a website, or a place where I can get this chart?

What do you mean by compositions? Are you looking for bathemetry charts or sediments types?

I have a FISHING HOT SPOTS map that shows this information. Mine is an old one of the Saginaw Bay. Maybe you could get one for the different areas of Lake MI. Mine shows R=Rock, S=Sand, G=Gravel, M=Muck, C=Clay.

DIRTY DOG, hit the nail on the head. I am looking for charts that show the bottom sediment.

Check with the US Geologic Survey. I have a really detailed one from 2001one in my office with sediment coposition from shore to 30 fow from St. Joseph south to the Indiana line.
