Why are some of the Lakes in Russia RED? What would cause that? [View All]

[Up2Late]

I was looking at some RAW Images from NASA's MODIS Satellite "Terra," When I noticed 2 lakes, East of the Volga River that are RED, here some link, Click the thumbnails to goto the MODIS links:



If you look to the East of the nearly angle turn in the Volga River, you can see the Red Lakes.



This smaller thumbnail goes to the RAW image I was looking at, they can be view at 4km, 2km, 1km, 500m, 250m resolutions. You can't see much (re: the lakes) until you get to the 500m or 250m resolutions.
