What the ground in Fond du Lac is like

In Fond du Lac, the leading limit is slow water movement: effluent does not drain through the soil fast enough, so a conventional field can back up or pond when the ground cannot keep pace. The survey flags that limit on about 89% of the rated ground here.

The limiting features the survey records most often here:

• Slow water movement89.3%
• Depth to saturated zone80.1%
