A massive landslide completely dammed the Chilcotin River in British Columbia , Canada , on July 30 .

Within 48 hours , the river had swelled significantly, breaking its banks at several points and forming a debris-filled lake.

The obstruction may have also doomed an endangered salmon population by preventing the individuals that survived the sudden damming from reaching their spawning grounds.
