How deep is the water table in MN?
10 to 30 feet
In Minnesota, the water table is commonly within 10 to 30 feet below the land surface, but can be more than 120 feet below the land surface in upland bluff areas near deeply incised river valleys such as the St. Croix, Root, Minnesota, and Mississippi river valleys.
How far down is the water table?
Groundwater may be near the Earth’s surface or as deep as 30,000 feet, according to the U.S. Geological Survey (USGS).
How do I know if I have a high water table?
The water table can fluctuate based on the weather or season. Areas that tend to have a higher water table are near water sources such as a river or lake. A telltale sign of a high water table is if your neighbors experience similar flooding issues or if your home is near a water source such as a lake, river, or marsh.
How deep should well be in Minnesota?
Wells in Minnesota range in depth from 15 feet to over 1,000 feet. Wells that are drilled very near each other often have similar depths. However, the depth of wells in glacial deposits can vary greatly — even if they are located next door to each other.
What is above the water table?
The soil surface above the water table is called the unsaturated zone, where both oxygen and water fill the spaces between sediments. The unsaturated zone is also called the zone of aeration due to the presence of oxygen in the soil.
Is it bad to have water under your house?
Puddles of water in the crawl space aren’t good, but the water itself won’t ruin your home. It’s the water vapor (or moisture) that causes rot, mold, energy loss, and attracts pests. And these problems don’t just stay in your crawl space.
How deep do you have to dig to find water?
You will need to dig at least 30 feet below the surface to find high-quality water. But you’ll need to dig even deeper to find better water that will be the safest for your family to drink. The water table rises and falls throughout the year.
Why is my water table so high?
Water tables can become elevated when they receive more water than they drain off. This can be from unusually high amounts of rain, or excess water from higher elevations. High water tables are often above the level of basement floors or crawlspaces. This almost always causes flooding in these areas.
