Okay, this is only for people who are deep, deep in the weeds. Every once in a while I get an email asking me for the sizes of SeaWorld’s pools. And I have never really had rock-solid information on the dimensions. So, apart from the insights into SeaWorld’s thinking about Tilikum, Haida, and Nootka contained in Russ Rector’s FOIA’d documents, I was glad to see that SeaWorld’s 1991 application to import and display Tilikum, Haida, and Nootka from Sealand included…..very detailed pool dimensions. So I have posted them below (I have left SeaWorld Ohio out since that is now closed).
One thing that jumped out at me from this section of SeaWorld;’s application is just how few killer whales SeaWorld had in 1991 (12, including Ohio), compared to the 29 they keep today (23 at SeaWorld parks, and 6 at Loro Parque).
So, for the record, here are the sizes of SeaWorld’s pools in 1991:

And people believe 15 feet of depth is enough for these animals? What world are we living in?
