As inundações recordes do mês passado levaram várias barragens no norte de Michigan à beira da falha, com a água quase transbordando uma barreira importante em uma das cidades. Os eventos renovaram os apelos para lidar com as barragens obsoletas do país em meio a tempestades mais intensas impulsionadas pelas mudanças climáticas.

As inundações no norte de Michigan no mês passado elevaram os rios a níveis recordes. Na barragem de Cheboygan, a água chegou a menos de 13 centímetros de transbordar no dia 16 de abril, levando as autoridades a considerar evacuações. Em Bellaire, as equipes colocaram cerca de 1.000 sacos de areia ao redor de uma estrutura centenária para evitar o transbordamento.
