35. Destination Africa, Calgary Zoo
36. Big Cat Falls, Philadelphia Zoo

38. Jungala, Busch Gardens Tampa
39. Mundo Maya, Dallas World Aquarium - this is more a zoo than an aquarium
40. Florida, Lowry Park Zoo

48. Carnivore Kingdom, Philadelphia Zoo
49. Primate World, Lowry Park Zoo
50. African Savanna, San Francisco Zoo - wow, my local zoo made the list!
Allen, I personally just don't like Mayan temples. Just my opinion.
On the underwater viewing part...and it is better than not having it at all. I think its better for a zoo to have it then not, for those few times an animal decides to use its pool it makes for an incredible experience. I think it depends on luck
My point is that you listed it as if it was an "obvious Plus" to not have the Mayan temple, when in fact, it's only a plus for you -- and a few others.
I just don't think something that "depends on luck" or is basically "hit or miss" should be MUCH of a factor in determining what is an incredible exhibit. For example, have you heard of the National Zoo's O-Line? For about 15 minutes a day, you can see orangutans swinging on a line directly above you, as they transport themselves from one side of the Zoo to the other. Honestly, I've never seen this great thing, but I've seen many pictures of it. If this experience were available to visitors for most of the day in Washington, I would consider the O-Line for my Top Exhibits list. But since it's 100% dependent on being at the Zoo at a specific time once per day, I can't rate it so highly. Quite honestly, the chances of seeing an elephant, tiger, or jaguar in the water are even more remote. Thus, while I agree it's better to have underwater viewing than not have it, this still isn't a major factor in highly rating an exhibit. It's a minor factor, but not a major one.
Count me as one who has yet to see Jaguar Cove. But even before it was opened, I think I could identify the problem with this "exhibit" -- it's very disjointed. You're never really sure whether or not you are still in the "Tropical Rain Forest" exhibit.
This of course can be a problem with ranking many multi-enclosure exhibits. For example, here at the Indianapolis Zoo, technically the "Oceans complex" includes the excellent Oceans building, outdoor polar bear exhibit, outside walrus habitat, and the amazing Dolphin Dome and show. If we can really consider these all together as "one exhibit", I think Indianapolis' Oceans complex has to be a Top 10 exhibit in the nation. But Jon and I didn't combine all of these, especially since it's quite a walk from the Oceans building to the Dolphins building. A somewhat similar thing is Kansas City's Africa exhibit. While the area is huge and has many different sections, I couldn't argue with anyone who wanted to consider this different exhibits. But IF you do consider this entire package as one exhibit (as I do, because of the strong continuous theme), then this HAS TO be considered a Top 10 (or Top 5) exhibit!
Let me answer a couple of specifics in your description:
(1) You repeatedly name its "absence of mayan temple" as if this is a "plus". It certainly is to you, but NOT necessarily for everyone else. To be, it's a "minus". I actually LIKE the Mayan temple in Jacksonville's jaguar exhibit slightly better.
(2) I've repeatedly pointed out that "underwater viewing" can be very, very overrated. When it comes to animals that are almost in the water -- hippos, polar bears, sea lions, otters, beavers, etc -- then underwater viewing is amazing! But for animals that are rarely (or only occasionally) in the water -- jaguars, tigers, elephants -- it's not a big deal. I've been to my local Indianapolis Zoo hundreds of times, and in those visits I've seen the elephants in the water maybe 3 times. I've seen the tigers in the water exactly once (I was with SnowLeopard at the time!). So thus Jaguar Cove's "underwater viewing" is really not that big a deal, same with the Bronx Zoo's Tiger Mountain. Even Omaha is very excited that in a few years they'll be opening (what they say is) the world's first elephant exhibit with underwater viewing. Sorry Omaha -- OVERRATED!
Yes, I have included Jaguar Cove in Woodland Parks Tropical Rain Forest, since it nearly seamlessly connects to the older part of the exhibit...there are even vines that drape between one of the jaguar viewing areas and the indoor forest building.
On Lowry Park, its interesting that their newer Africa exhibit area ranks lower than the ones on my list. Something about it seemed disjointed.
Zoos I have visited that have no exhibit complexes on my list:
Miami Metrozoo
Los Angeles Zoo
Tierpark Hellabrun - I don't remember any specific exhibits here in 1995
Schonnbrunn Tiergarten - ibid
Biodome Montreal
Phoenix Zoo - was there in 1985
Oakland Zoo
Wildlife World Sydney - nice place but hard to break it up into exhibit areas
Lion Country Safari Irvine - closed
St. Augustine Alligator Farm
Hartleys Crocodile Adventures Cairns
Santa Barbara Zoo
Santa Ana Zoo
Charles Paddock Zoo
Are there any great themed multi species exhibit complexes in Pittsburg?
The Africa savanna section is pretty good, but doubt it'd make a list like this.
The Water's edge which features polar bears, sea otters, and eventually walruses is good, and could make the list, especially once they get the walruses.
I'd rate the Pittsburgh African exhibits well above the very disappointing Water's Edge (see Snowleopard's review).
Missing from these lists are the Desert Grasslands and Upland Desert Trail at ASDM (peccary, lizard, coyote, "Life on the Rocks,"), Minnesota Zoo's Minnesota Trail and Russia's Grizzly Coast (from all reports), Cleveland's Wolf Woods, and Binder Park's Africa.

@geomorph: It never ceases to amaze me how great zoos can not have any exhibits worthy of a top 50 list. I love the Miami Metrozoo (all moats and no bars) and yet there is nothing there that would make my own list of top exhibits. I've seen "Amazon and Beyond" and think that it needs years of growth to become a great set of enclosures, and "Wings of Asia" is borderline brilliant but I'm not a huge bird fan.
I'd rank the Columbus Zoo in my top 5 zoos, but everything there is quite good but lacks true world-class status. Probably nothing would make my top exhibits list, even though I have no problem classifying it in my top 5 zoos.
