Yeah, we motored around the area where the town of Kosmos used to be. The shallowest we came across was 15 feet deep. I know the blasted bridge is downhill from the town, so it was probably 25-30 feet underwater. That channel is actually the entry into the lake for one of the boat launches when the lake is not at full pool. Jet drive guys in aluminum bass boats really don't care, and I am sure that structure makes a great fishing spot. I'll use a different launch, thank you very much!
In February I drove my truck out there and we hiked around looking at the ruins (foundations, roadways, bridges, and some railroad tracks). It is pretty weird to take the boat to a place I have driven before on dry ground. Heck some of the locals were actually out having a bonfire & BBQ right at the cross roads in downtown Kosmos! Today I would need a snorkel to see it though.
I'll post a picture tomorrow of what really scares me at this lake.
