agreed a single EHD case doesnt make sense-- but in the wild world a lot of things dont add up.
The EHD here has taken a toll on the most mature deer
Unless your game department is testing for CWD there probably wont be any confirmed cases, you simply can not tell looking at the condition of a deer if its CWD.
3rd possibility is predators-- an there it would be coyotes, could be the buck took to the water to avoid them after being chased, being exhausted he drown, far fetched I know, but i have seen a full grown bull elk that ran into a huge snow drift to get rid of coyotes, the coyotes finally won
regardless of what it was a true loss, I hate seeing a mature animal die like that sounds weird but I would rather see a buck live an outsmart me then die from an unknown, nature is cruel
