What the ground in Ham Lake is like

The USDA soil survey rates mapped ground in Ham Lake for septic drain-field suitability across roughly 34 square miles. About 100% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.

In Ham Lake, the leading limit is seepage in the bottom layer: water moves through the soil too quickly. That is the opposite of a slow-drainage problem. The risk is untreated effluent reaching groundwater before the soil can clean it, not backup at the surface. The survey flags that limit on about 100% of the rated ground here.

The limiting features the survey records most often here:

• Seepage, bottom layer100.0%
• Filtering capacity66.5%
• Depth to saturated zone65.2%
• Ponding49.1%

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.
