diving for fly rods
last fall I dove (in a wet suit) in the dix river tailwater to get my friends Orvis rod. Even on a warm November day (60s) it was ice cold. We couldn't see it from the surface. I think that is because I expected it to be laying flat on the bottom. In this case, it was pointed straight up in about 10 feet of water, making it very hard to see if you're looking down. Just my two cents from experience. Glad you are both OK and good luck finding it. My understanding is that if you can even retrieve part of the rod, they will replace it.
