Average Annual Groundwater Recharge

This dataset contains long-term average (1975-2003) annual recharge estimates for the seven-county Twin Cities metropolitan area. Values are in inches per year. Recharge was estimated using a daily soil-water balance (SWB) model developed by the Wisconsin Geological and Natural History Survey in conjuction with a regional groundwater flow model developed for the Twin Cities metropolitan area. This dataset was developed by Barr Engineering Company for the Metropolitan Council to support the development of the Twin Cities metropolitan area regional groundwater flow model (Metro Model 2).<br/><br/>More information about this process is provided in the 2009 Metropolitan Council report 'Twin Cities Metropolitan Area Regional Groundwater Flow Model Version 2.00 - Technical Report in Support of the Metropolitan Area Master Water Supply Plan', which is available online at www.metrocouncil.org/environment/WaterSupply/metrogroundwatermodeldatasets.htm.

dsPurpose The 2005 Minnesota Legislature directed the Metropolitan Council to "carry out planning activities addressing the water supply needs of the metropolitan area" (Minnesota Statutes, Section 473.1565). Specifically the Council is charged with developing a base of technical information for water supply planning decisions and to prepare a metropolitan area master water supply plan. This dataset supports this charge.
