Chadegan's Lake - Beautiful water-ways - a lake formed by a dam across the upstream somewhere.       The first night we were having our dinner in a eating place facing the majestic river but was not aware of the surrounding in the dark.  Not until we returned the following morning for breakfast I discover how pretty the scenery was. The greenish-blue water,  the  dream-like undulating distant hills and the 'contour-like' lines marking the nearby hillocks.  The flow trickled to a few inches deep 10 Km in the east at Esfahan - in Zayande River.
