This map illustrates the current extent of the Ataabad Lake as detected in Radarsat-2 satellite data recorded on 15 May 2010. The lake was caused by a landslide across the Hunza River on 4 January 2010, in Hunza-Nagar district, Pakistan. The lake is currently rising due to recent glacial melt and rainfall, and there is a distinct threat of sudden outflow / overtopping of the dam. The pre-landslide Hunza river extent was extracted from ALOS ANVIR 2 satellite imagery recorded on 10 September 2009. It has been estimated that approximately 7.5km of the Karakoram Highway (KKH) has been flooded by the lake and at least two main bridges have been submerged. This flood assessment is a preliminary analysis & has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT. Map scale for A3: 1:50,000; Projection : UTM Zone 43N; Datum : WGS-84.
