Seems to me that 680.10 applies to "pools" since it didn't add the words "and similar installations", nor did it add words "body of water", so it doesn't seem to me that your water feature falls under the scope of 680 for any other item than pools.
The closest thing in 680 to your water feature would be fountains -- and as defined in 680.2, it wouldn't have to have any energized parts to fall under the category of "Permanently Installed Decorative Fountains and Reflection Pools".
