The Lower Minnesota Watershed meeting on November 15, went very differently
than expected. At the beginning of the meeting we did our usual plea of
"Save and Preserve Coldwater". Again many people spoke to the importance
of the Spring, the danger posed by the Southwest
Loop Pond, and the horrible record of near complete destruction
to similar sites in the past. Daniel Dorgan: "Regarding the impact of the holding pond and Camp Coldwater
Spring, as you know Kelton Bar issued a report in mid September, and we
had our consultant analyze that report, Short Elliott Hendrickson (SEH)
is our consultant, and they are registered geologists or hydro geologists...and
it is their belief that the scenario that Mr. Barr presented was highly
speculative and they did not agree with the conclusions that Mr. Barr
reached on the impact to Coldwater Spring from the construction of the
interchange and the pond. They have done extensive studies in the area,
and that is still their position. Never the less, as the watersheds, and
Mn/DOT and the DNR discussed the pond, and their was...not the level of
comfort from regulatory authorities that we would like to see. We agreed
to look at three alternatives to address the issues that Minnehaha Creek
had brought up. And that's what brought us together tonight. To look at
those three alternatives and select one for the redesign for the pond.
It is still our position that the original pond design does not impact
Coldwater Spring. And any of the three alternative designs similarly will
not impact Coldwater Spring. That is based on the reports by our consultants..." Malkerson then added to the top of the last page of the permit, after the first sentence where it says "the water elevation of the spring... that a positive gradient to the spring will be maintained" then added "Based upon the analysis of all the information submitted the board finds,...their will BE No Impact on the springs by the pond". Then he suggested a revision to previous permits approved in June, the
Lower Mn reserved the right to revoke the permit, or propose additional
conditions on Mn/DOT, to "Eliminate any such impacts, should significant
impacts to Camp Coldwater Spring occur, as a direct result of this pond"
so it is a duty for Mn/DOT to ELIMINATE any such impacts. As stated in Kelton Barr's report
it says "Water table piezometers and monitoring wells indicate that the
(original) pond level is more than 5 meters lower than the existing water
table." and that in the Peer review,
it states " Briefly, it is clear in the SEH (2000) report that the groundwater
model constructed to predict the effects of dewatering at the interchange
could not be verified experimentally shown to be correct). I also saw
no indication of any sensitivity analysis to test the reliability of the
initial calibration. Not including some sensitivity analysis is a major
omission and atypical of what is now required of groundwater modeling.
Because the model could not be validated, either the model design was
wrong or the data put into it were wrong." Plus a third outside hydrologist,
Michael E Schoenberg has stated that there will be permanent damage to
Coldwater. So we asked why not raise up the road, so the pond can be even
higher to eliminate any potential of damage. Why not raise the road, what
is holding it at it's low level. The only answer we got from Mn/DOT was
that Hwy 55 will go over Hwy 62 and that is why Hwy 62 is being lowered
for that overpass to be. The next day Mn/DOT drafted and sent
the following letter to us
