Yep. But it's a standard WDFW provided metal pole, wire and fake grass blind.
“Hunting is restricted to the blind.”
Pretty obvious they've been burnt off that blind by previous hunters, no doubt sky busters or very poor shots since dead ducks have a hard time remembering .
Also, just because the WDFW put a blind there doesn't mean it's a favorite spot of the ducks. Just maybe the birds don't like the area the blind is in that much. Time of year, feed available, water levels etc can effect where birds go and what they do.
