Lion Drinking Water Fountains in Hermann Park around 1980?

Hello from San Antonio, Houston!

So I am working on a treasure hunt to pass the time as a brain teaser (see r/12keys if intrested), and I just have a fairly specific question that I have been going crazy trying to figure out, and I might as well post it here and try my luck.

So in the Houston Zoo, I know there is at least one Lion drinking water fountain that has been there since around the 1960s at least. These fountains were supposedly placed by The Lions Club in various parks.

So my question is twofold.

1) Is or was there more Lion drinking water fountains, or just the one within the Zoo?

2) Were there any of those drinking fountains outside the zoo, just situated around Hermann Park in 1980?

Any and all serious replies are appreciated, because I have spent a lot of time trying to find out and have had no success. Thank you!

Also I am on mobile, so I apologize for formatting issues, if there is any.
