Unless you can't stand the heat, fishing at night is not necessary to catch good size crappie at the Vine. Look for brushpiles in 15 - 25' of water. Fish minnows or jigs very slowly. You'll catch fish.

Rob, this is the time of year that the bigger fish move out of the docks. Slip/Dock fishing on Grapevine is good October-May but usually best January-March.

I was hoping although slower during the day that maybe the night fishing under a light would still be productive in 13 feet?

I've never done any good at night on Grapevine. Best bite this time of year is from about 8:00 am to 11.30 AM and from about 2:30 PM to 6:00 PM. They seem to shut down around 6 pm.

I think you are right! Last 6 weeks I've been catching them starting about hour after sunrise, they go slow after lunch, and then pick up until 6-7pm.

I just had to go try it for myself though. I arrived at 8:15pm last night and should have left after 15 minutes. I caught 2 keepers and some undersized in the remaining 15 minutes before sunset. I then went 4 hours with basically nothing! Not even any real nibbles, about hour after sunset I caught a 12-13" Channel and then finally at 11:30 I caught a 9.75" Crappie. I called it the night at 12:15.

The Green Monster fishing light was working great though! Within about 30 minutes it was bringing in the fry and small minnows! Never really saw any big fish except maybe a large shad or small drum now and then. By the end there was just a huge tornado of small minnows circling the light! Any chance this light would actually scare off the fish or were they just not there or more likely not biting? I can see why the Crappie get all over the minnows as most of the natural minnows are small and shad are too large, I think minnows are just the perfect size for them and rare so they can�t resist.

Here is video I took of the minnows circling the Green Monster.
