There appears to be good comparison between water level fluctuations and the trend of <br />precipitation relative to normal around Ham Lake and Spring Lake. Dave Ford used the <br />WATBUD model to evaluate the data, and found a correlation between the fluctuation of Spring <br />Lake and climate (see a=hment). <br />trod Withdrawal <br />Mounds View and Fridley have municipal wells in the Prairie du Chien -Jordan Aquifer and a <br />buried artesian aquifer within two miles, of Spring Lake. Well log data shows these aquifars are <br />hydraulically separated from the water table aquifer by layers of clay. Nonetheless, pur aping <br />from these aquifers will inm-ease the potential for leakage from the water table aquifer, which <br />could be lowering level of Spring Lake over the long 'term. <br />I believe the three foot decline of the Spring Lake water level from the spring of 1999 the <br />spring of 20O0 was clirnate-related. Municipal weUfield pumping could be inducing Ic ikage <br />from the surficial aquifer, possibly causing a long term decline of the Spring Lake water level. <br />If Spring Lake monitoring shows continual lake level decline, recording devices could 'n placed <br />in an existing observation well near the shore of Spring, Lake and observation well 201 1) or 2014 <br />to see if pumping mVmcts are apparent. <br />C: Brian Rongitsch <br />Pale Homuth <br />M <br />
