Secondary ditch system $198, 900 
Bridges 89, 260 
Flowage rights 284, 760 
Contingent expense (about 10 per cent) 123,770 
Total 1, 400, 000 
This estimated cost, if raised by special benefit assessment placed 
on the 112,370 acres of land which would be affected directly by the 
improvements, would approximate $12.50 per acre. The assessment 
could of course be made less than that amount per acre by placing 
a part of the expense on the 1,087,630 acres of land which com- 
prise the upper portion of the watershed. Some benefits would also 
accrue to the lands north of Wahpeton. It is impossible to estimate 
closely the probable cost to the various interests until the laws under 
which the improvements will be constructed are known. The cost of 
reclamation is, however, very reasonable when the value of the. land 
as it now is and as it will be when drained is taken into consideration. 
RED LAKE— RED LAKE RIVER PROJECT. 
The plans for improvements in Eed Lake and Red Lake River 
as recommended in the report of the Corps of Engineers, United 
States Army (see House Doc. No. 61, 66th Cong., 1st sess.), con- 
template the construction of a dam and sluices at the outlet of Red 
Lake for the control of lake stages and outflow, the building of 
rock jetties for the protection of the outflow channel, and the enlarge- 
ment and straightening of the upper 45 miles of the Red Lake River 
channel. The construction of a lock for navigation is also consid- 
ered but not recommended as necessary at this time. Certain fea- 
tures of the project are here described which are closely related to 
the larger Red River project described later. 
RED LAKE. 
Red Lake has an area of 441 square miles. The adjacent land on 
the north, east, and west is low and flat with small streams and 
drainage ditches entering the lake. The land to the south is high 
and rolling and of a sandy character. During periods of high water 
the lowlands are overflowed and the drainage systems rendered in- 
operative. Commercial navigation is carried on to a limited extent 
in the lake which is of ample depth for the purpose. The approxi- 
mate elevation of extreme high water is 1,177 and of extreme low 
water 1,173, giving a range of 4 feet. 
It is proposed to limit the lake to a range of 3 feet by a control 
dam at the outlet, providing for minimum and maximum surface 
elevations of 1,171 and 1,174, respectively, for calm-water conditions, 
with an allowance for Avind tide of 1 foot, bringing the extreme 
stage up to 1,175. The range of 3 feet will provide a storage capacity 
.
