Heavy Snow and Depth Perception

I was reminded today with the heavy snow that was coming down just how much it can affect your depth perception. i seemed to be off on so many casts, more then normal, and was continually caught up in the over hanging shit that blesses are river banks. now obviously when you are casting to tight quarters your are gonna snag up from time to time but i had a really hard time getting my casts dialed in and i blame that on the heavy snow that was coming down. got into a good amount of fish but not much to hand.
