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 Red Lake and Red Lake Eiver 

 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. 



EED 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 sj^stems 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 wind tide of 1 foot, bringing the extreme 

 stage up to 1,175. The range of 3 feet will provide a storage capacity
