Tom just returned from a flight to Kalskag. He was looking for ice jams and flooding along the Kuskokwim. Each year residents along the river try to predict the scale that spring break up flooding will bring each village. When the river breaks it forms Ice jams that act as dams and contain the melt water from upstream. So far there are just a few cracks open and some shoreline melting. But the residents upstream are moving their valuables to high ground and making sure there is food and emergency gear in their boats.
