To CMJC: Hi
Thanks for your comment. why so much grey water? It's mud. When buffalos after buffalos go to the same spot of water, it will creates mud like in this photo. You may have seen farmers in developing countries use buffalos to run their rice paddies to make the soil soft before they plant rice, it will also create the same mud and grey color but the differences are the mud are harder in order to hold the roots.
