This appears to be a Diamond-backed Water Snake in distress. It is a large snake—approaching 4ft/1.2m in length—and something is wrong with its eyes. It’s not clear what. It is possible that something went wrong the last time this snake shed its skin, and the old skin somehow adhered and stayed attached to the snake’s eyes. It is also possible that its eyes are simply covered in dried mud. Whatever the case, the one thing that is certain is that this snake could not see.
Later that afternoon we encountered another Diamond-back Water Snake swimming freely through a small pond. This snake was perfectly healthy and provides a nice contrast to the ailing snake we found earlier. Notice its clear mahogany eyes.
