Ground-water recharge in Minnesota:

USGS Fact Sheet 2007-3002, by Delin, G.N. and Falteisek, J.D. This report, prepared in cooperation with the Minnesota Department of Natural Resources, summarizes findings from recent research papers, but is presented in a form for a broader audience.

Average annual recharge to surficial materials in Minnesota (1971-2000) estimated on the basis of the regional regression recharge (RRR) model. Several new USGS publications on ground-water recharge in Minnesota determined:

  • Ground-water recharge rates to surficial materials in Minnesota typically are about 20-25 percent of precipitation and vary regionally (see map below) based on climate, soils, and other data.
  • High-quality, long-term, continuous hydrologic and climatic data are important to estimating recharge rates.
  • Water-level measurement frequency is important in estimating recharge rates.
