pumped to return to the lake, we would be 
able to obtain sufficient amount of this ma- 
terial to insure at least a foot covering 
over the entire sand fill. Samples of this 
mud were carefully analyzed and the re- 
sults showed that with a mixture of from 
one-eighth to one-quarter part sand, thor- 
oughly worked, no better soil for lawn pur- 
poses could be obtained. 
These plans being drawn up, same were 
adopted by the Board of Trustees, and a 
new contract covering pumping of sand, 
also top covering of mud for soil purposes, 
was entered into with the La Crosse 
Dredging Co. The estimate on this con- 
tract was not to exceed 500,000 cubic yards 
of material and at an increase of 4 cents 
per yard over the former contract price. 
This increase was made to cover the in- 
stallation of dredge and excavator and the 
casting of dykes necessary for mud cov- 
ering. 
Clearing and engineering work was 
rushed so that early spring saw operations 
again resumed. 
The outline of the proposed lake having 
been established, the excavator was placed 
in operation casting up embankment, and 
excavating an opening for launching of 
dredge. Operations proceeded in a similar 
manner to those of former season, with 
the following exceptions:* 
In hydraulic dredging, an average of at 
least 85 per cent of pumping consists of 
water. This means that with each day’s 
operation the disposal of at least 1,500,000 
gallons of water is to be contended with. 
As we were not permitted to sluice water 
onto any adjoining property, our only re- 
course was by natural outlet, and even in 
doing this we were obliged to return all 
water to the lake to prevent the light ma- 
terial and sediment from obstructing con- 
duits on adjoining land. 
Our plan was to eventually handle the 
water flowing through creek in center of 
swamp by a large conduit. This conduit, 
starting from Lake Calhoun, would have 
discharge in our proposed lake. Again 
starting at the outlet of proposed lake, 
would continue direct to Lake Harriet. To 
have constructed this before first filling the 
swamp would have been useless, as it 
would undoubtedly have been destroyed by 
subsidence. Our method of procedure was 
to complete the filling under the course of 
the conduit without obstructing the creek. 
This would allow its construction during 
winter and would permit filling the bed of 
the creek the following season.
