I'm not sure if anyone keeps official "lake records" for Cordell Hull. If anybody does, it would be the Resource Manager's Office for the Corps of Engineers. That's who maintains the Lake Records for Old Hickory and Percy Priest.
You'll note that the Corps Resource Manager's webpage for Old Hickory and Percy Priest list the lake records (the link is under the FAQ section). The Cordell Hull page does not. That leads me to believe the Resource Manager for Cordell probably does not keep lake records.
In case you're curious, here are the Old Hickory and Percy Priest lake record pages:

The only way to be sure would be to call and ask.
