Title

Regional Ground-Water Recharge Estimates for Minnesota

Abstract

Estimated average annual ground-water recharge rates in Minnesota based on the regional regression recharge (RRR) model.

Purpose

These data represent average recharge from 1971-2000 to surficial materials. They can be used wherever regional estimates of recharge are needed, for example, preliminary estimates for ground-water models.

Lineage

 

A regional regression model was developed to estimate the spatial distribution of ground water recharge in subhumid regions. The regional regression recharge (RRR) model was based on a regression of basin-wide estimates of recharge from surface water drainage basins, precipitation, growing degree days (GDD), and average basin specific yield (SY). Decadal average recharge, precipitation, and GDD were used in the RRR model. The RRR estimates were derived from analysis of stream base flow using a computer program that was based on the Rorabaugh method. As expected, there was a strong correlation between recharge and precipitation. The model was applied to statewide data in Minnesota. Where precipitation was least in the western and northwestern parts of the state (50 to 65 cm/year), recharge computed by the RRR model also was lowest (0 to 5 cm/year). A strong correlation also exists between recharge and SY. SY was least in areas where glacial lake clay occurs, primarily in the northwest part of the state; recharge estimates in these areas were in the 0- to 5-cm/year range. In sand-plain areas where SY is greatest, recharge estimates were in the 15- to 29-cm/year range on the basis of the RRR model. Recharge estimates that were based on the RRR model compared favorably with estimates made on the basis of other methods. The RRR model can be applied in other subhumid regions where region wide data sets of precipitation, streamflow, GDD, and soils data are available.

Soils data obtained from STATSGO; precipitation data from the Minnesota State Climatology Office (G. Spoden), 2003, electronic communication; growing-degree-day data from Midwestern Regional Climate Center, Champaign, Illinois (S. Shea), 2006, electronic communication. Processing of data fully described in Lorenz and Delin (2007).

The methodology is documented in: Lorenz, D.L. and Delin, G.N., 2007, A Regression Model to Estimate Regional Ground Water Recharge: Ground Water, v. 45, no. 2, 13 p.

General information about ground-water recharge in Minnesota is available in: Delin, G.N. and Falteisek, J.D., 2007,Ground-Water Recharge in Minnesota, U.S. Geological Survey Fact Sheet 2007-3002, 6 p.

The RRR method is compared to other methods of estimating recharge in: Delin, G.N., Healy, R.W., Lorenz, D.L., and Nimmo, J.R., 2007, Comparison of local- to regional-scale estimates of ground-water recharge in Minnesota, USA: Journal of Hydrology, v. 334, no. 1-2, p. 231–249.
