Speaking of diving, I happened to sneak out this weekend. A buddy and I went
up to Lewis Smith Reservoir, in the upper part of the Black Warrior River
drainage, north of Jasper, Alabama. The Corps had drawn the water down to
winter pool, roughly 30 ft lower than normal. Visibility was great on the
surface, but became gruesome below 80ft or so. On our 20 ft deco stop, I
noticed some freshwater sponges growing on a bridge abutment. They were
substantially different than other sponges I've seen in FW, being low,
crustose, and milky white. I'm kicking myself now for not getting a sample
(I had taken the zip-locs out of my drysuit pocket as I was packing my
vehicle, thinking I wouldn't need them). The weird thing is, while most FW
sponges are usually found in less than 10 ft of water- during the summer,
these would have been at least 50 ft deep... The only fish either of us saw
was a lone Morone saxatilis that visited us during deco.
cheers,
Dave
