Potential for Ice Jams and Related Flooding Greatest in February and March

The Montana Department of Natural Resources and Conservation (DNRC) is reminding residents that February and March will have the greatest potential for ice jams and conditions can change rapidly. According to the Glasgow National Weather Service, ice jams have already impacted the Missouri River in Wolf Point and Poplar, which made the Missouri River run high on Jan. 23. “Montana experiences the highest number of reported ice jams in the continental U.S., with most occurring in February and March” said DNRC Director John Tubbs in a press release. “Flooding can happen in any community and it can happen quickly. Residents in flood-prone areas should take steps to safeguard their families and property.”

Insurance Commissioner Matt Rosendale and the DNRC is advising Montana residents to prepare for flooding by purchasing flood insurance well in advance of warmer temperatures as policies typically don’t take effect until 30 days after purchase. “People living near rivers or streams should be especially mindful, as ice jams can cause flooding earlier in the season than many expect,” stated Rosendale. A release issued by the Commissioner of Securities and Insurance state most homeowner’s policies do not cover flood insurance and about 20 to 25 percent of all flood claims come outside of a high-risk flood area.

Worby McNamee, a DNRC floodplain specialist, said it’s important that residents living near a river or stream develop a flood evacuation plan and consider the following steps besides purchasing flood insurance: keep extra drinking water on hand, as flooding can compromise local water systems; shovel or plow snow away from homes and structures; and be ready to transport valuables or where practical, elevate them.
