What the ground in Stillwater is like

The USDA soil survey rates mapped ground in Stillwater for septic drain-field suitability across roughly 30 square miles. About 89% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.

In Stillwater, 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 87% of the rated ground here.

The limiting features the survey records most often here:

• Slow water movement86.5%
• Depth to bedrock37.4%
• Flooding16.9%
• Slope9.8%

This is survey data for mapped areas, not a substitute for a site evaluation on your own lot. Conditions on a single parcel can differ from the map.
