Draft North & East Metro Groundwater Management Area Plan 4-19 <br /> Objective IV. Well Interferences and Water Use Conflicts <br /> Well Interferences <br /> There have been no confirmed well interferences16 in the GWMA. Potential for well interference is <br /> considered when evaluating new water appropriation permit or amendment applications. <br /> Water-Use Conflicts <br /> There are no known water use conflicts in the North & East Metro GWMA. As discussed for Objective I <br /> above, current uses appear to fall within safe yield thresholds for the area. Future requests for <br /> additional appropriations will be evaluated for potential to exceed safe yield due to cumulative impacts <br /> of permitted users. <br /> Protection of groundwater-dependent surface water features and biological communities may require <br /> limiting water appropriations in some areas. It is possible that water use conflicts could arise if <br /> cumulative impacts of more than one existing or proposed appropriations would risk negatively <br /> impacting these resources. Implementation of improved analysis methods and data for evaluating <br /> surface water impacts could reveal water use conflicts not previously identified. <br /> Gap Analysis and Recommendations <br /> Well interference is almost always a local issue. Local data will continue to be needed to evaluate the <br /> risk for well interference due to new or amended appropriations.These evaluations will continue to use <br /> pumping tests and/or local aquifer monitoring where needed on a site specific basis. <br /> 16 A well interference complaint is confirmed to be valid only after DNR receives a complete Water Well <br /> Information and Complaint Questionnaire and finds through an investigation that well interference caused a water <br /> outage. <br /> 77 <br />
