CAMPBELL, N.Y.(WENY)-- This afternoon, Campbell School District released their students to go home at 12:15 p.m. due to the possibility of flooding. The national weather service released that there was a chance of ice jams forming in the Cohocton river and causing floods to break out due to water build up. These jams first occur due to frigid temperatures freezing the water. The water freezes and becomes extremely thick and heavy. When the temperature warms up like it has these past few days, the ice begins to melt and break apart. This is when the concern for jams begin. The hunks of ice will float down the river and potentially get caught in narrow areas of the river and on the river bed. When this happens, they create dam like structures that will back the water up and cause flooding. Another risk can be that the water pressure is high enough to burst through the dam and either cause an extreme rush of water or for the jam to move further down the river and possibly get stuck again. To stay save in these situations, it is best to stay as far away from the river as you can. The flood warning has been lifted since 5:45 p.m. today.
