THE LAKGEST ELECTRIC POWER DAM Df THE WORLD, NOW BEING BUILT ACROSS THE 



MISSISSIPPI RI\"ER, AT THE NEW HOME OF THE AMERICAN BEE JOURNAL, 



AT HAMILTON, ILLINOIS— DAM BEING OVER HALF MILE LONG. 



This view was taken Apnl 4, 1912, from the outer edge of 

 the cofferdam, on the Iowa side, 1000 feet from the Iowa shore, 

 looking across towards the Illinois shore. The city of Hamilton 

 is at the extreme right. There arc to be 119 arches, 82 of which 

 now show in the ;jicture. The puwer-house, lock and dry dock 

 are now being built on the Iowa shore. The immense power will 

 be generated by 30 turbines of 10,000 horse-power each. The fall, 

 caused by the Des Moines Rapids to be flooded, is from 20 to 36 



feet, according to the stage of water. The cities of Keokuk and 

 Hamilton, on either side of the big river, have become centers of 

 activity, and have a bright future. A view of the entire works, 

 taken from the Iowa bluffs, will be published later in the American 

 Bee Journal. 



This immense undertaking, which is to cost over $25,000,000, : 

 was planned, and is now being carried out, by Hugh L. Cooper, 

 probably the most capable hydraulic engineer living.
