I've seen
North American River Otters at
115 zoos. It's a staggeringly high total because I've only ever seen the species at ONE European zoo out of 120. That means River Otters are one of the most common species I've ever come across and almost every sighting has been in an American collection. For me, River Otters in American zoos have been more common than Meerkats, Coatis, Raccoons, Wolves and just about every single mammal species.
In fact, after Tigers, Lions, Ring-tailed Lemurs and Bobcats, I think that North American River Otters are #5 if I'm looking strictly at USA collections. They are absolutely everywhere in the USA and that includes
16 aquariums on my list.

Woodland Park Zoo (USA) has two large viewing panels for its River Otter exhibit and there are many photos of the underwater viewing in the gallery. But I'd like to also highlight that there's a small hidden moat that separates the otter enclosure (foreground) from the Rocky Mountain Goat exhibit in the background. It's a very special backdrop.
Being able to see the ballet-like underwater acrobatics of River Otters is key to a visitor's appreciation of these inquisitive mammals.
Oregon Zoo (USA) is one of many collections with expansive viewing windows.
It was recently renovated and modernized, but the same basic structure remains that has held River Otters for decades.
Calgary Zoo (Canada) has a large cabin-like building with viewing windows into a River Otter habitat.
Does anyone remember the old River Otter exhibit at
Jacksonville Zoo (USA)? This is what it looked like when I visited in 2008, but it was soon converted into a Magellanic Penguin exhibit.
Kansas City Zoo (USA) has a spacious, modern River Otter exhibit near the zoo's entrance:
Just like Jacksonville,
Saint Louis Zoo (USA) has a River Otter exhibit that is no longer in use. I saw River Otters in the image pictured below (the
Chain of Lakes waterfowl area) and in fact Saint Louis Zoo had
TWO River Otter exhibits back in 2010 as there was a second one in the now closed down Children's Zoo. Now the zoo lacks River Otters. Are there otters included in the new plans for that 2.8-acre area that opens in 2026? I think the answer is yes!
What some American zoos have done in the past 15 years is to incorporate kiddie slides into their River Otter exhibits. Here's a splendid example at
Akron Zoo (USA), where an otter can be seen swimming over the acrylic tunnel. As a father of 4 children, I think the idea of a slide is fantastic.

I really enjoyed seeing the River Otter exhibit at
Buffalo Zoo (USA) in 2010, with its significant land area to go along with the pool. That stonework is also a treat.
Maryland Zoo (USA) has long been recognized as having one of the very best River Otter exhibits around. There's a spacious pool and land area, plus a visitor tunnel that one would normally see in a shark tank.
@Astrotom3000
A mini version of the Maryland exhibit is the River Otter enclosure at
Saginaw Children's Zoo (USA). There's an underwater viewing area, but also a forested zone as well. Oakland Zoo (USA) is another establishment with a similar setup.
An indoor River Otter exhibit with a sunshade! The
Appalachian Cove Forest complex at
Tennessee Aquarium (USA) has a River Otter exhibit that is typical of many U.S. aquariums. There's mock-rock galore and crystal clear viewing windows, so obviously there's no outdoor access for the animals, but here's an example of one of the better all-indoor River Otter exhibits in the nation.
@Moebelle
Cameron Park Zoo (USA) had a kiddie slide and some white rocking chairs in front of their River Otter exhibit in 2010. Time to beat the Texas heat.
It's a bit shocking to go through hundreds of photos of River Otter exhibits and see how many of them lack natural substrate anywhere in the enclosures. There's a ton of otter exhibits, such as this one at
Virginia Aquarium (USA), that have mock-rock mudbanks and no actual dirt or debris anywhere. Of course, by having fake landscapes it stops the clogging of water filtration systems.
Another example of an indoor River Otter exhibit that has a mock-rock, mudbank backdrop is at
Florida Aquarium (USA). This whole thing used to be netted, but it was taken down and a kayak was added instead.
@SwampDonkey
If one is willing to accept the dozens of all-indoor, mock-rock River Otter exhibits with spacious pools, then the species does okay in captivity and breeds regularly at many facilities. But there's occasionally a head-scratching exhibit such as this one at
Bear Country U.S.A. You can see a River Otter on the grass and a tiny pool with a crashing waterfall at the back. It's a bit odd.
The worst River Otter exhibit I've ever seen is probably the diabolical one at
Ellen Trout Zoo (USA) in Texas. It was very tiny, with a puny, filthy pool at the front. This is an AZA-accredited zoo as well!
The other contender for 'worst' River Otter exhibit would be the one at the now closed
Special Memories Zoo (USA) in Wisconsin. This was the entire space for the two otters and the brown water reeked.
Even though it has a spacious pool and underwater viewing windows, I appreciate the significant land area in the River Otter exhibit at
High Desert Museum (USA). Since I took this photo in 2015, the facility has renovated the enclosure and replaced the solid wall with yet more windows. Look at that stunning forested backdrop!
One of the best River Otter exhibits I've ever seen is at
Sequoia Park Zoo (USA), with its naturalistic appearance and rolling terrain.
One of my all-time favourite River Otter exhibits is found at
Northeastern Wisconsin (NEW) Zoo (USA). It's arguably the largest one I've ever seen, has lots of grass and trees, and a series of ponds as if it's set inside a fancy botanical garden. Gorgeous.
