Stopping Leaks in a Big Mississippi Dam.

Stopping Leaks in a Big Mississippi Dam.

Fissure through which water was seeping was discovered recently in the main cofferdam of the $25,000,000 Mississippi river power dam now under construction at Keokuk, Ia. A big force of men is dumping cement into the break in hope of stopping the leak, and dynamite within the cofferdam has been removed. When the water was a foot deep on top of the main cofferdam, the ice gorge that has surrounded the dam broke, sweeping away the power house. The force of the flood also carried out three transmission towers of the Keokuk-Hamilton bridge.

The abuse of artesian resources prevails in the Antelope Valley, California, according to Harry R. Johnson, of the U. S. Geological Survey. At the time he visited the field 60 uncapped wells, flowing from 1 to 15 miner’s inches each, were wasting 2,721,000 gallon per day.
