If known, provide the name of specific resources that may be impacted. Identify <br />what the greatest risks to the resource are and how the risks are being assessed. Identify any resource <br />protection thresholds – formal or informal – that have been established to identify when actions should <br />be taken to mitigate impacts. Provide information about the potential mitigation actions that may be <br />taken, if a resource protection threshold is crossed. Add additional rows to the table as needed. See the <br />glossary at the end of the template for definitions. <br />Some of this baseline data should have been in your earlier water supply plans or county comprehensive <br />water plans. When filling out this table, think of what are the water supply risks, identify the resources, <br />determine the threshold and then determine what your community will do to mitigate the impacts. <br />Your DNR area hydrologist is available to assist with this table. <br />For communities in the seven-county Twin Cities metropolitan area, the Master Water Supply Plan <br />Appendix 1 (Water Supply Profiles, provides information about potential water supply issues and natural <br />resource impacts for your community. <br />Table 10.
