March 13th 2017, I caught my 2nd DD (10.13lbs--24.75in long) on grapevine. it was a SUPER windy day and I probably should not have been in my kayak fishing near the dam, but I always have a fluke, TX rig worm, or a crawfish TX rigs (lightest weight I can) and almost dead stick it between my retrieves back.
hope that helps, grapevine for me is a hit or miss lake, but I love fishing around rocks in general so it has a special place for me.
