Ground-Water Recharge in Minnesota
G. N. Delin, J.D. Falteisek
2007, Fact Sheet 2007-3002
'Ground-water recharge' broadly describes the addition of water to the ground-water system. Most water recharging the ground-water system moves relatively rapidly to surface-water bodies and sustains streamflow, lake levels, and wetlands. Over the long term, recharge is generally balanced by discharge to surface waters, to plants, and to deeper parts...
