The claim: West of Brigham City - contains a WWII internment camp that was built before the game preserve was established.
What it really is: What is true about this claim is that there is a migratory bird refuge west of Brigham City. What is not true is that a World War 2 internment camp was located in there.
There is a defense depot located in near by Ogden, that was used a POW camp during World War 2. The depot site itself was closed down in 1997, and while some buildings are still used by government agencies, the site has mostly been converted into a commercial and industrial park.
