Here you can see just how bad the water sits after a torrential down pour. The area you can see flooded furthest away, I have fixed. It now drains back to the field to the far right. I just dug a trench for now but will have to properly dig it out and put in drain tile.

The area closest is just right of the pic above. The well pump is just off to the left of the pic. This is the area I want to keep wet.

Do you think crawdads will cause a problem for the bog plants?
