What is coldwater creek lake?</h3>
The lake was created during the 1980 eruption of Mount St. Helens, which blocked its natural outlet, Coldwater Creek, with volcanic debris. It is one of several lakes in the area that were created or otherwise enlarged by the eruption.
The lake was completely vacated after the eruption as well as the eradication of all life forms except for bacteria, which can be a source of a new life in lake.
