I see the parcel changed ownership from the Hunts to the Phillips, but the Army Corps of Engineers still has the dam listed as "Hunt Lake Dam" (NID #MO31076) as of 05/25/2018 [1].

Is there a freely-accessible, official source naming this water body "Phillips Lake"? If a business operates here, then marketing material will suffice in my opinion.
