The Colorado Department of Public Health (who by the way are AWESOME) have a sub page on specifically this:
https://cdphe.colorado.gov/animal-related-diseases/prion-dis...
(it links to the page you provided)
As noted on the webpage you linked, there is a very clear set of rules and processes related to testing hunting-harvested animals in known areas of concern as well as testing of road kill to manage surveillance:
"In 2024, CPW will require mandatory submission of CWD test samples (heads) from all deer harvested during rifle seasons from specific hunt codes to better evaluate the prevalence of CWD in herds. Hunting is the single most effective tool wildlife managers have to monitor and manage the spread of the disease. By submitting harvested animals for CWD sampling, Colorado’s hunters provide critical information about where and how the disease is impacting deer, elk, and moose herds in the state."
