- When cities are a little *too* close to their water tables…
- Columbia is launching a new Global Flood Initiative, described in the post: Before the Flood: Predicting the Deluge
Flooding on the Red River has crested in both Fargo and Grand Forks. Now it’s on its way north to Manitoba, and farms and towns in Minnesota and North Dakota are left to clean up the mess it left behind (and take down all those sandbag levees they worked so hard to put up just a few weeks ago).
- Amazing picture of traffic on flooded Interstate 29, near Fargo.
