Is this Moraine Lake? I've canoed there if so.
Also, Biff is right about tubing on the New, but I'd go further north to Scottsville instead of Todd. Go to New River Outfitters. I used to work there summers when I first started teaching. Beautiful stretch of river.
Scottville is up close to the New River State Park - great area. The river around Todd is still a little small and can be shallow, depending on the recent rain status - but the area is pretty remote and beautiful as well. The River Girl outfit in Todd does a great job with fishing tours and the like - not sure if they do tubing as well. The New is great for smallmouth.
