Typically I look for sand areas that are real close to main current. Actually a nice current break around these areas is a huge plus. As far as depths go, they can be real shallow 2-5ft or considerably deeper 10-15ft. The area that I have fishing lately is a little on the deeper side.
The wingdams are a huge magnet too. These areas can congregate some very large fish this time of year. All areas on the front face of the wingdams should not be overlooked. The airport area has been a solid producer in the past for evening fish. Look for the current breaks and be patient. Catch a fish before dark? stick close to that area, because that is a sign that these fish are nearby and utilizing the surroundings. It pays to get out before the sun goes down and really look at area closely to pick the spots apart before you setup camp. Be careful out there as Pool 2 is littered with wingdams. One false steer and that could be the end of a night in a hurry. Bring a spotlight to identify the channel buoys.
Hope this helps.
Oh yeah, Jig sizes……. I have been keeping several rods rigged with relatively the same offerings that my other rods have but I like to have a good selection of jig sizes tied up. If you feel you exhausted a school of fish to the point of not getting any more bites? Change up the size and give a little different drift speed to your bait and you would be surprised how that can make a difference.
