Where can I get bathymetric maps of freshwater areas?

[Anony]

After searching on scubaboard and google for the last couple of days I've found fish'nmaps and many lovely ocean maps, but not one of the lake I am looking for (tulloch reservoir, CA)

Is there a place I can go for all my bathymetric needs?

have you checked NOAA? I know they have them for the ocean, I think I saw some for lakes, at least a few of them.

Just finished, no luck :/

never looked for those, but I have always found good topo maps at the National Geological Survey. Might be an option, or maybe someone there would know of a source.

I know in Michigan you can obtain lake maps from the most popular lakes from the Michigan Department of Natural Resources. Perhaps California has a similar service?
