THE IRRIGATION AGE. 



Whereas, The sanitary district of Chi- 

 cago, a municipal corporation organized 

 under the laws of the state of Illinois, has 

 constructed an artificial channel from Eo- 

 bey street, Chicago, to Lockport, and has 

 heretofore been granted permission by the 

 secretary of war to make certain improve- 

 ments in the Chicago river for the purpose 

 of correcting and regulating the cross sec- 

 tion of the river so as to secure a flowage 

 capacity of 300,000 cubic feet per minute, 

 with a velocity of one and one-quarter miles 

 an hour, it being intended to connect the 

 same artificial channel with the west fork 

 of the south branch of the Chicago river at 

 Robey street in the said city of Chicago ; 

 and, 



"Whereas, The said sanitary district of 

 Chicago has now applied to the secretary 

 of war for permission to divert the waters 

 of the said Chicago river and cause them 

 , to flow into said artificial channel at Kobey 

 street as aforesaid ; and, 



Whereas, The aforesaid district of Chi- 

 cago represents that such movable dams 

 and sluice gates as are necessary to, at all 

 times, secure absolute and complete con- 

 trol of the volume and velocity of flow 

 through the Chicago river have been con- 

 structed ; 



Now, therefore, the chief of enigneers 

 having consented thereto, this is to certify 

 that the secretary of war hereby gives per- 

 permission to said sanitary district of Chi- 



cago to open the channel constructed and 

 cause the waters of Chicago river to flow 

 into the same, subject to the following con- 

 ditions : 



1. That it be distinctly understood that 

 it is the intention of the secretary of war to 

 submit the questions connected with the 

 work of the sanitary district of Chicago to 

 congress for consideration and final action, 

 and that this permit shall be subject to 

 such action as may be taken by congress. 



2. That if at any time it becomes appar- 

 ent that the current created by such drain- 

 age works in the south and main branches 

 of Chicago river be unreasonably obstruct- 

 ive to navigation or injurious to property, 

 the secretary of war reserves the right to 

 close such discharge thro ugh said chan- 

 nel or to modify it to such extent as may 

 be demanded by navigation and property 

 interests along said Chicago river and its 

 south branch. 



3. That the sanitary district of Chicago 

 must assume all responsibility for dam- 

 ages to property and navigation interests 

 by reason of the introduction of a current 

 in Chicago river. 



Witness my hand this 8th day of May, 

 1899. 



R. A. ALGER. 

 Secretary of War. 

 JOHN M. WILSON, 

 Brigadier-General, Chief of Engineers, U. 

 S. A."
