please see the Twin Cities Metropolitan Area Groundwater Flow Model Version 3.0 (Barr, Metropolitan <br />Council 2014). <br />2040 Regional Scenarios <br />Regional scenarios were run using the model to evaluate the effects of forecasted groundwater <br />withdrawals to the region's aquifer system. <br />Assumptions <br />Population and Population Served <br />The 2040 population for the communities within the seven -county metropolitan area are the population <br />forecast values developed by the Metropolitan Council. Communities that disagree with the Council <br />population forecasts and are actively changing the population forecasts with the Council; the <br />community supplied population forecast is being used. New growth is assumed to be served by the <br />municipal system. For a more detailed explanation of population served please see Appendix 2 of the <br />Master Water Supply Plan (Water Demand Technical Memorandum) <br />Water Demand <br />Municipal water demand was projected to 2040 water use using 2002-2012 data and community input. <br />For more information of water demand please see the Water Demand Technical Memorandum. <br />Between 1988 and 2012 water use for industrial, agricultural, and commercial use has been fairly <br />consistent when compared to municipal demand. Therefore, these uses are assumed to remain <br />constant through 2040. <br />Water Sources and Well Locations <br />Sources for municipal use were assumed to remain the same as current sources. Communities were <br />contacted and asked to comment on well locations and sources. Communities fell into four categories: <br />• Communities served by surface water or by another community <br />• Communities who do not plan to drill any more wells <br />• Communities who plan to drill more wells and provided the locations and aquifers <br />• Communities where locations and sources were the same as in Metro Model 2. For more <br />information please see Metro Model 2 Technical Report 2010 Master Water Supply Plan <br />Appendix E (Metropolitan Council 2010) <br />See the table below for a list of communities and the category where they fell. Projected water use in <br />excess of 2003-2011 average water use was evenly distributed among future wells. When a community <br />did not plan to drill future wells the excess water use was evenly distributed among the existing wells. <br />Community <br />Supplied by <br />Another <br />Community <br />No Wells <br />Planned <br />Locations and <br />Sources Updated <br />Locations and Sources <br />Same as Metro Model 2 <br />Andover <br />X <br />Anoka <br />X <br />Apple Valley <br />X <br />Arden Hills <br />X <br />
