Yes there are bass in there along with grass/armored carp, bluegill, channels, some have yellow bass. My friend has a house on one of the lake front areas in Ocotillo. Unfortunately he and I believe the home owners association or someone put chemicals into his lake and killed off most if not all of the fish in there. One day he all of a sudden saw a massive die off of maybe a hundred fish which continued for a week or so alota Large mouths, tilapia and grass/armored carp. Also you must be a homeowner to be able to fish most of thoes lakes he has to carry a homeowners card with him just incase he gets stoped. If you wanted to take a chance the lakes inside residences can carry bass, but all the outside lakes which you can see are not filled with very many fish.
