OVERFLOW OF RED RIVER OF THE NORTH. 89 
to or greater than that of 1897 would cause much more damage than 
was caused by that flood. By improving the river channel as pro- 
posed, flood heights could be reduced by 5 feet or more and addi- 
tional outlet facilities needed in some localities would be provided. 
Benefits which would accrue from improved drainage outlets such 
as are proposed in the Lake Traverse-Bois de Sioux project would 
add greatly to the value of the land affected. 
It appears, therefore, that the two projects are well worthy of 
adoption. The benefits that would be secured during future periods 
when large run-off occurs, such as now causes floods, will be large 
enough to warrant a considerably greater expenditure than will be 
necessary to obtain relief from these conditions.
