Des inondations records le mois dernier ont poussé plusieurs barrages du nord du Michigan au bord de la rupture, l'eau ayant failli déborder d'une barrière clé dans une ville. Ces événements ont relancé les appels à remédier au vieillissement des barrages du pays face à l'intensification des tempêtes provoquées par le changement climatique.

Les inondations qui ont touché le nord du Michigan le mois dernier ont fait monter les rivières à des niveaux records. Au barrage de Cheboygan, l'eau s'est approchée à moins de 13 centimètres (5 pouces) de déborder le 16 avril, incitant les autorités à envisager des évacuations. À Bellaire, les équipes ont placé environ 1 000 sacs de sable autour d'une structure vieille d'un siècle pour empêcher tout débordement.
