I hit the Rappahannock River today. Bumping this thread rather than starting a new one, as the previous poster is the person that posted up the information below on Divebuddy.
Rappahannock River - Fredericksburg VA | DiveBuddy.com
A few things:
-I started from the entry point that the previous poster mentioned.
-The water was 78*.
-Use a diver down flag or safety sausage (I did the former, but will do the latter next time). It's shallow and there are a LOT of kayaks and canoes around. While the current wasn't ripping... if you pop-up to get your bearings without a surface marker (it's only ~4-5' deep at most spots), you could get brained by a human powered a boat.
-The water was relatively low, so the spot that I found 7' at would likely be ~10' during rainy season.
-The visibility averaged ~5-10', though some spots dropped below that. There were a bunch of kids in the water maybe 100 yards upstream, so I doubt that did the visibility any favors.
-Not a lot of critters today. I crossed over to the opposite bank and skirted the downed trees. I only saw one smallmouth bass, but it was a good sized fish. He/she hung around to see what I was up to for a few seconds. See if you can spot the fish (center of the image and towards the top). This gives you an idea of the average visibility.
-Wear gloves. Even if it "looks" calm from the shore, there's still some current once you get out there. Heading downstream is a "drift" dive. Getting back upstream will likely involve pulling yourself along the bottom rock to rock. Either that or completely exhausting yourself by kicking against the current. I opted to go with the crawl along the bottom option, which I think was a good way to go.
