Dent in the rim. Need your opinion please

It looks like I have a really bad luck with wheels this year! I bought this wheelset a just few months ago. Yesterday, I went over some sewage or drain cover with loaded bike (full panniers with groceries) and felt bike dropped there with rear wheel. Quickly checked: no flat, tire was Ok, and wheel spun fine. I rode it for 20 miles more before noticing today some pulsing. Took a closer inspection and found a dent in drive side.
  • Dent is quite big (to my untrained eye)
  • Bulge is quite small, maybe fraction of 1mm
  • It is Mavic A719

I know there is a lot of latitude about what's OK and what isn't with dented rims, and I would like to get your expert opinion:

1. Should I attempt to repair myself (my home bike mechanic skill are Ok, but not super great)?
2. Should I bring it LBS?
3. How quickly should I replace it? (asap, ride a bit, don't really worry about it).

Thank you very much for your help in advance.

Looks fine to me. I rode to work today on rims that are more scraped up than that.

I had a similarly dented wheel. After going ahead and getting a new rim, I took a second look at the rim and decided it was not as serious as I had first thought. I very carefully straightened the dent filled and sanded the area with 180 grit sandpaper over a sanding block. The dent is barely visible.

brake pads will feel the width bump.. you, as said above, could fix that.

Lightly sand off any high spot where the brake pads contact it. Aluminum is soft, don't overdo it! Just take the worst off.
Don't worry about an inward dent, the pads will ride right over it.

Your photo looks like no sanding is necessary. Maybe just smooth off any rough edge where the tire contacts it.

Thank you so much, ThermionicScott, berner, fietsbob and rm -rf for reassurance I watched a few videos on youtube about removing dent from the rim with crescent wrench and flathead screwdriver. Would you recommend me going that route or just send that little bulge off with high grit sandpaper?

EDIT: Just saw rm -rf's comment. Thanks! That is what I will proceed to do. Will try to be more careful next time!

Yes to mild straightening of the rim lip with an adjustable wrench...

I wouldn't begin to attempt to straighten it with a wrench, etc. The rim is bulged inward and outward, I don't know what you would actually straighten. Take a very fine file to the brake track to remove the outward bulge eliminating the pulsing. You may want to file the inward bulge also.

The damage of the two are not comparable.
