Purpose This appendix summarizes water use, source, and potential issues for each community, county and watershed in the seven -county Twin Cities metropolitan area. The information in each water supply profile is generally based on regional information and should be refined with more locally specific characteristics to better evaluate potential issues. The profiles provide a useful starting place for local planning and can be used in several ways, including: • To inform community water conservation programs by helping to target large water use categories • To complete local water supply plans in a way that considers Metropolitan Council policy and the Master Water Supply Plan • To inform water supply -related permit applications and environmental review documents Target Audience • Community planning staff • Public water supply utility staff • County planners • Watershed planners Methodology and Supporting Data Overview of water systems and use in the community Information about the current status of the community's water system came from a review of past local water supply plans, data submitted to the MN Department of Natural Resources as part of the water appropriation permit program, and information submitted to the MN Department of Health and stored in the Minnesota Drinking Water Information System (MNDWIS). The information will be updated based on information provided through the public review process for the 2015 Master Water Supply Plan. Number of high capacity wells permitted by DNR within the community The number of high capacity wells in each major aquifer in the community was determined by counting the number of municipal and private water appropriation permits, as reported in MN Department of Natural Resources water appropriation permit database called the State Water Use Data System (SWUDS), located within the community boundaries. Average annual water use by permitted users since 2003, in key water use categories The average amount of water used by major categories between 2003 and 2012 came from MN Department of Natural Resources water appropriation permit database called the State Water Use Data System (SWUDS). Available options for water supply sources The list of available options for water supply sources was developed through a public outreach process that included input by sub -regional work groups. More information about the approach to outreach is available in Chapter 1 of the Master Water Supply Plan. More information about these options is described in Chapter 4 of the Master Water Supply Plan.
