Yes, it's toast. Also, boards are made of hazardous materials that cost a fortune to dispose of properly, but I'll do you a favor and take care of it. You just have to ship it to me.
Seriously though, I'm sure you'll soon have much worse from riding. My first day on my brand new board I gouged the base deeper than I have since. Unless it's a core shot or you bent your edges, I wouldn't do anything.
