Can Sea Mammals Live in Fresh Water

I was reading about the Lake Baikal Seals and got to thinking about this.

If I took a walrus or whale or dolphin or manatee or any other kind of sea mamman that normally lives only in salt water and put it in Lake Michigan, for example, could it live OK?

I mean assuming it could find food and such, and I realize manatees need warm water, but let's ignore that for the moment.

Is the fresh water seal a unique thing that they developed or could any sea mammal go from fresh to salt water without issues?
