Well good. Where is the "wall" and I work just north of Benbrook so give me a point there too. Might meet you out there to have someone to fish with if you want. So yellow bass like it after dark?
Yellow bass bite OK after dark but I do not fish after dark these days. Both lakes are unsafe.
The Wall is an old retaining wall. To get to the Weatherford wall take I20 to the Ranch House Road exit. Turn right (north) on Ranch House Road for 4 miles. After you cross the 4 way stop at Lake Drive continue for 1/2 mile to a little park on the left. Park. The wall extends from there towards the dam. Walk towards the dam and look for schooling fish. If you don't see them schooling cast as far as you can into the lake and retrieve slowly. Small shad are the bait of choice.
With Benbrook down as far as it is a boat would be my only recommendation. If the lake comes up this spring the yellow bass will be in the creeks.
