Gilgit, June 3: The data available on water passing through the spillway at Hunza River lake is conflicting and confusing.
According to NDMA Chairman the water flow at Ganish Bridge is around 2100 Cusecs. Subtracting water inflow from small torrents and water channels, it can be said based on NDMA data, that at least 1900 Cusecs of water is being discharge from the lake. Taking the water flow through seepages at around 350 would take volume of water discharge per second through the spillway to around 1550 Cusecs. If true this would indicate a significant single day jump of around 600 Cusecs in the discharge rate.
However, according to other sources, water discharge through the spillway is around 1150 Cusecs while the seepage discharge is around 350 Cusecs, taking the cumulative discharge to around 1500 Cusecs.
The amount of erosion has also increased according to reports and increased pressure on the barrier might destabilize it and lead to dam breach within a relatively shorter span of time. Next 24 hours have been termed as highly critical for stability of the dam.
Public circles have demanded more coordination between institutions monitoring the lake to avoid confusion and misinformation.
