After the lake began to flow through the spillway that was cut into the landslide debris on May 29th, the flow of the water has increased, but still does not match the inflow upstream from the Hunza River. And - as is evidenced by these two images (May 30th on the left, June 4th on the right), the outflow is eroding the debris, working back toward the lake - potentially signaling an upcoming breach whre nearly five months worth of river flow might wash away the dam and cause serious flooding downstream. Scientists and authorities are monitoring the situation and evacuations have been undertaken for all threatened areas.
