if it's for you, the pickings are bad to worse.
The pond in greenways was really good last year for catfish and big carp, but between super hot water temps killing them off, and the red necks finding out (really, you are keeping a cooler with 20 carp in it?) it's pretty useless now.
THe best is probably southeast park in canyon, but that's mostly bluegill, tiny bass, turtles and the random holdover trout.
