I just heard back from a good friend Rich Swartz, who lives on Lake Anna, and now owns Duke's Creek Marina. He said the lake is almost 3 feet low, but navigatable. He just bought Duke's Creek Marina, which honestly, used to be really rough to launch a powerboat, but I have not seen the upgrades he has done. Feel free to call him at 540-895-5065; and/or use the link below which should help too. At this point, it does not look like I am going.
