WPLN-FM's review of Department of Environment and Conservation and Tennessee Tech University emails shows enthusiasm for the system just after a fatal 2017 flood.

In May 2018, department procurement contacted Tech professors about the vendor. The park manager told the professors that the parties were crafting a legal document.

In subsequent months, both expressed frustration.

Environmental commissioner David Salyers asked about the system this year. May and June emails show people trying to assess where things halted.
