Wekiwa Springs and Wekiva River: What's in a name?

Wekiwa Springs and Wekiva River.  Yes, this is confusing how can we have two spellings and pronunciations for the same body of water? 

Wekiva Springs
Headwaters of the Wekiva River

For many years known as Clay Springs, the name was reverted to Wekiwa in 1906.  Earlier it was called Wekiwa, named by the Seminole Indians and interpreted as “spring of water”. Now the river also carries a Seminole name, Wekiva, which means “flowing water”. Although Wekiwa and Wekiva are sufficient identifiers, we non-Seminole need additional terms thus the labels Springs and River.
