first, try california crossings. its a spillway on the elm fork of the trinity river just east of las colinas. there's a history of good production out of there. especially when the water is running over the spillway at a good clip. i've been going there since i was 15. you'll find lmb, sandies, and catfish. many other species that i have not targeted but have seen caught. if you're looking for size, i've personally seen a few 30-40 lb catfish pulled out of there and have listen to old timers swear that 60+ lbs have been caught. it's not a secret place by any means. and it's definitely not a place to take the kids for a day of fishing. there's a few gravel pits very very nearby that have produced as well. the one literally next to it has lmb, crappie, gar, etc. the one across the street has a good production of well sized crappie. i cannot emphasize enough that it's not a place for kids to hang out. i personally don't like the idea of my kids hanging around people drinking all day. although, in their defense, i have never had any problems with the people out there that do.
google maps is emphasized so much because it really is a great source of help for so many people looking for places to fish. the spots that are labeled on the Texas Google Bank Fishing map are good places to start but are in no means the only places to go. many of the guys that have been on this site for years truly do want to help people beginning to fish by doing the best thing they can - give tips and ideas and get fishermen to explore.
