When groundwater near one of these features is <br />pumped excessively, water levels in the surface water feature may decline and water quality changes <br />may occur. <br />Some examples of surface waters under the influence of groundwater include: <br />• Itaska Lake in Anoka County <br />• Seminary Fen in Carver County <br />WATER SUPPLY MASTER <br />PLAN- Draft June 2015 <br />
