Pictures: The Iranian salt lake that turned blood red

    An Iranian salt lake which was hit by drought turned red could be saved.

    Urmia Lake in northern-western Iran changed back to a healthy blue colour after bouts of wet weather rejuvenated the waters. Amazing photographs taken from space showed the scale of the drought.

    After weeks of dry conditions the water level had became so low that red-coloured micro-organisms turned the lake into something resembling a horror film. Nasa’s Aqua satellite captured images of the red lake with its Moderate Resolution Imaging Spectroradiometer. Experts aren’t sure which tiny creatures turned the lake red but they believe they likely to be either algae or a type of bacteria known as Halobacteriaceae.

    The colour changes are a common sight in the spring and early summer due to seasonal precipitation and climate patterns, Nasa said.

    Spring is the wettest season in north western Iran, with rainfall usually peaking in April and snow on nearby mountains also melts.
