Sounds like either hydrophobic soil or a pest/disease may have been your culprit. Pics may help, as well as knowing a little more background.

I'm not trying to overwhelm you, but as you can see, there is a lot of information that may help to isolate the issue.
Yes, irrigation was 100% as far as coverageSpammage said:For example, do you have irrigation, did you check the heads for coverage, was it raining frequently or a drought when the condition showed up, was it Summer or Fall when cooler temps and fungus may have been more prevalent, did you apply anything new to the lawn before this occurred or anything familiar that you may have been heavy handed with, did you put down grub poison last year, did you try a soapy water test or see any worms or numerous moths, etc.

Not typically. He's a male, so he usually goes to one of the bushes. I do have a female, but it's completely random with her and not just in that spot. I'll try the screwdriver and see. It's been, by far, the healthiest part of the lawn for nearly 8-9 years until last season.Spammage said:When you take your pic(s), try to push a screwdriver into the ground. That will help to determine if there is anything under the soil preventing the grass from thriving. Also, I noticed the dog, is this problem area where the dog usually relieves itself?
No I've only used a push mower on the lawn but am looking at getting a d125. Also as far as a screwdriver, it sank right in there with no problem at all.Spammage said:Screwdriver test? It is strange that the area to the right (in the top pic) looks good, but 5-6 feet into the yard is where this seems to start. One other thing that crossed my mind, is this an area where you turn the D125 around multiple times?? It also appears to be a slight mound - do you notice crop circles when you mow?
I was thinking it may be too early for the grubs as they burrow down deep during the winter, hopefully we figure it out soonw0lfe said:Well did the soap and water. No grubs surfaced, just tons of earthworms.
I have not done a soil test.. Any recommendations on one to purchase from Amazon or anywhere?Colonel K0rn said:When was, or are you planning to do, a soil test?
