We have a problem with some uneven spots in our yard that becomes a bigger issue after a lot of rain. I'm attaching a picture from the yard after last week's downpour.

I've had some major work done on field line installation last year and this section is a result of that. I know that the only solution is to bring in dirt and work on leveling it out, but I wanted to get advice on the best way to do this.

Thanks in advance for your help!
