But a high water table may not always be a bad thing. … The researchers found high water tables can provide much-needed water during drought and to crops planted in coarse-grained soils which have a harder time retaining water than their fine-grained counterparts like silt loam.

What causes a high water table?

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.

What is the water table and how can it be lowered?

If water is withdrawn from the ground at a faster rate that it is replenished either by infiltration from the surface or from streams then the water table can become lower resulting in a “cone of depression” around the well.
