You should have a look at the new 1.3 dataset from October last year,
this is where the split between the different types was introduced. I'm
absolutely not sure if lake data has been improved but I actually do
have some hope. The GSHHS data in my DB is already the most up to date.

With the split GSHHS datasets the great lakes have been separated from
ocean data (to my memory). If the appropriate attributes are being
applied to the respective lake geometries, a task that I think is being
done in Terragear, there should be a chance to get things sorted out.
Cheers,
Martin.
