Minnesota Historical Society puts up historical marker at Camp Coldwater in July 1991.

January 9, 1999 Star Tribune editorial authored by Bob McFarlin (MnDOT's then director of public affairs) in which he states:
The very best the community can do is study all the potential impacts thoroughly, factually and within the law, and then exercise informed leadership for the good of all. The Hiawatha Corridor Project is a shining, successful example of this type of community consensus.

August 1998 MnDOT told the Indian Affairs Council:
"When completed, the new roadway will not impact the Camp Coldwater site. Construction is not expected to impact the flow of underground water to the Camp Coldwater spring."

An April 1999 MnDOT study states that "Coldwater will not be affected by construction"

May 25, 1999, MnDOT states in court (under oath presumably)
"We've measured the hydrostatic pressure in the soil and in the [Platteville] limestone and they are not connected...There's no construction that we have had design for that impacts the limestone in any way. All our construction is limited to the soil layer" (Mr. Wetmore, pg. 109, lines 2 through13)

October 1999 MnDOT stated in a public news release;
Camp Coldwater Spring was not identified in either the 1983 or 1985 statements because the project avoids the spring, located on Bureau of Mines property. The project has been designed to avoid impacting the flow of groundwater to the spring. Mn/DOT will monitor both water quantity and quality during construction to insure that the spring is not impacted.

June 2000, MnDOT releases a groundwater study on Coldwater (as an alternative to a dye test that MnDOT said they wanted to do first). Concerns having been raised with an underground storm water sewer line cutting the flow to Coldwater, MnDOT does the right thing and raises the grade of the road from South 54th Street to Highway 62 to avoid impact.

The only remaining segment in question is the Hwy 55/62 interchange itself.

November, 2000, MnDOT once again states "no impact" to Coldwater spring, at the Lower Minnesota River Watershed District public meeting. At issue is a stormwater holding pond that threatened the Coldwater Spring. Then Daniel Dorgan official spokesman of MnDOT agrees to raise the pond a few feet and also to:
"Eliminate any such impacts, should significant impacts to Camp Coldwater Spring occur, as a direct result of this pond"

MnDOT was so confident that their construction would not impact the spring, they agree to this language in their permit for construction
"So if, weather it's three months from now, six months from now, or six years, or sixty years from now, there is a problem, and it is because of this, this board has reserved to it's self, the right to revoke the permit, or impose whatever conditions are necessary, to eliminate the problem."

MNDOT'S CONSTRUCTION PERMITS HAS ALWAYS BEEN BASED AROUND THE UNDERSTANDING THAT IT WILL NOT IMPACT% COLDWATER SPRING!
