Arctic temperatures raise risk of ice dams on Kennebec River

KENNEBEC JOURNAL • January 10, 2022

With frigid temperatures predicted for the first part of the week, weather forecasters say the conditions are good for ice formation on central Maine lakes and rivers. But with ice formation comes an elevated risk for ice dams. Ice jams form regularly in the Kennebec River, particularly in Hallowell and Farmingdale. As long as the river is able to continue flowing under the jam, there should be no cause for concern. But if the ice shifts and starts to block the flow, that can result in a large amount of water piling up in a small amount if time. Areas of Augusta and Hallowell flooded in mid-January 2018,when a period of heavy rain followed a stretch of arctic weather in central Maine.
