Do I need a new wheel or is there something I can do about this?

what happened?

Really depends on how deep the gauge is. Can't really tell from this photograph. Rims these days are made to be really light, meaning they are pretty thin. A deep gauge could cause a rim to break while you're riding, which is never a good thing.

Looks like a scratch, sand it smooth so it doesn't cut at the pads. You don't have to make it disappear, just so it isn't sharp. Looks like a hole above it.

Not sure... I hit the brake this morning and heard the harmonious melody coming from the rear break. Stopped and saw that

The dot above is not a hole but one of the tire nubs that I caught head on.

I am going to try sanding it and see what happens. It does not look like it is deeper than the wear-dots, but we'll see. Any one else have any ideas?

Crisis averted. Sanded smooth and all is well again! Thanks guys!
