According to your comments SDMF your pulling fish out of 30+ft of water and are either pillaging them or releasing them only to see them float.
Also, you must've did a county audit this summer on the vacancy of all the lodging to know they were booked all summer.
I don't have to fish in 30' of water to know when other folks are. If you've spent any time on the Debul it's plenty easy to know if folks are fishing deep or shallow. There's a well defined old shoreline @ 22'-25' and the deep structure isn't exactly a secret, one can cypher folks fishing many of those from a mile or more.
Walmart, Cenex, Charras and TQ, Proz @ the Cove, Pizza Ranch, AppleBees, DQ, McDonalds, Ace, HOE, Pete's, The Ranch were all as busy as any other summer. Plenty of "Help Wanted" adds on the radio all day-every day, didn't hear or see much for "Going out of Business" signage or advertisements.
I don't go to the Casino and I don't go to Ed's so I can't speak for them. Everyplace else in town was bustling all summer. Campgrounds will be expanded spring of 2021.
