Did I mess something up?

I noticed a big blue shape all over the map here:


If you zoom out it goes away, but zooming closer it is still there. I added a park and pond here:


Could all this blue be from something I did?

Yes, it could be that you’re the culprit. Please take a look at the natural=water tag on the map features page and at the pond that you mapped. Is the water on the right-hand-side of the way which defines the pond?

Another possibility is that there is an error in the coastline of the USA somewhere in that area.

I think you are seeing the same issue I am seeing in my post…


If you look 1/2-3/4 of North America is covered in water when you zoom in close enough.
