Bob,
I do not know about the Columbia River, but I can tell you about the
Great Lakes (I live out here now).

All of the lakes are cold (in the case of Superior - Damn Cold), some of
the lakes have very low oxygen at the deeper levels because there is
very little vertical circulation. Some of the best logs recovered are
the oaks and such that do not rot easily in any case.

This is why the lakes have been a wreck divers paradise, but you have to
be ready for the cold. Until the Russians buying Canadian grain brought
us zebra mussels, many wrecks either wood or iron looked like they could
be pumped out returned to service.

Come spring dry it out and sail a tight boat that wont leak.



freshwater will be your worst enemy, causing rot.


So why did I know a guy in the Great Lakes who was under water logging
100+ year old submerged logs? Also, same thing happening in the
Columbia River. Logs that got waterlogged (interesting word) 100 years
ago and sunk out of the log rafts. Fine years later. no rot?

Now why would a log not rot in fresh water????

I like the idea of packing it with salt. One of the reasons the Scow
Schooner ALma in SF Bay survived was that it hauled salt for years. Or
so the PR says.
