That looks like my Sheila lol (the bass). I caught her a few years ago fishing a tournament there. CKCrew is correct, there's a bunch of dinks in all the ponds. The city designed it this way so people could catch fish. They won't be huge generally, but they will catch fish. The "Horseshoe" pond probably has the biggest bass out of all the ponds. All of those ponds get pressure so the bigger bass rarely bite artificial baits. They've been around long enough to know the difference most of the time.
A bass that big out of any of those ponds are rare, so your wife should feel extremely proud to catch a bass of that size there. I've been fishing those ponds before they were even open to the public and never caught anything that size until a few years ago. She can hold her chin up high and know she is one of the few and be proud. I only know of 2 other fish being caught in any of those ponds that are that size or bigger and 2 of them are mine lol.
