You could try
Marine Creek lake Loop 820 West @ Marine Creek Pkwy - I haven't had much luck there yet but I have only tried Lure fishing so far and I'm a bank beater, it might help if I had a boat.
Little Fossil Creek I35 @ Western Center Blvd - I fish this often and usually catch a bass or two but there is a lot of construction going on here and it's interfering with my fishing right now...I wonder what they are building.
Alliance Airport I 35 N @ Alliance Blvd - I have caught a few Bluegill/Greenies on the ponds out here.
Clear Fork Trinity river 183 S/Southwest Blvd at Ridglea Country Club Dr - I have only fished this once and had moderate success, I caught a handful of Juvenile Bass.
Unknown Lake/Pond I20 Service rd @ Bryant Irvin Rd...City Lake Blvd -no clue what the name is but it has Bass and Turtles lots of Turtles!
Lake Worth Creek Silver Creek Rd @ Heron Dr - I have tore it up on this creek during the Spring, fishing for Sandies. This past weekend I caught an 8lb Cat, two 3 Lb Bass with Live minnows under a bobber.
And Finally Tx Parks and Wildlife, list of community fishing holes...Scroll down to Tarrant County.
