What U.S. state experienced widespread flooding along multiple rivers in March and April 2026, leading to evacuations?

Michigan experienced significant and widespread flooding along several of its major rivers during March and April of 2026, prompting numerous evacuations across the state. A combination of above-normal precipitation throughout March and early April, coupled with melting snowpack in northern regions, saturated the ground and led to rivers overflowing their banks. This sustained period of heavy rainfall and snowmelt overwhelmed drainage systems, causing water levels to rise rapidly and stress critical infrastructure, including dams.

The flooding impacted a broad area, with a flood watch spanning both the Upper and Lower Peninsulas. Rivers such as the Grand River near Grand Rapids, the Muskegon River, the Cheboygan River, the Manistee River, and the Red Cedar River in East Lansing all saw substantial rises in water levels, with some approaching or exceeding historical records. This resulted in submerged roads and trails, rendered airport runways unusable in some northern areas, and caused water to encroach upon homes.

In response to the escalating situation, Governor Gretchen Whitmer declared a state of emergency for 33 counties by mid-April, enabling state resources to be deployed for local relief efforts. Evacuation orders were issued for residents in flood-prone zones, particularly downstream of dams that were under increased hydrological stress, such as the Croton Dam on the Muskegon River and the Alverno and Cheboygan Dams in Cheboygan County. The persistent wet weather and subsequent flooding created a "crisis mode" for many communities, highlighting the interconnectedness of weather patterns, land conditions, and infrastructure in the Great (Review) Lakes State.
