On the 10th anniversary of the historic flood of 2012, we take a look back at the event that dumped 7.5-10 inches of rain on top of the Northland's already-sodden landscape.

In this video feature by digital producer Dan Williamson, News Tribune and Superior Telegram staff recall the iconic stories and photos of the event, with 2012 News Tribune video footage of the flood.

This timeline of the June 2012 Northland flooding originally published in print and online Sunday, June 24, 2012.

The National Weather Service in Duluth issues a flash flood watch for Northeastern Minnesota for Tuesday and Wednesday, with a forecast of "2 to 4 inches possible through Wednesday morning, with some spots receiving even higher amounts." News of the flash flood watch is posted at duluthnewstribune.com that evening, and is included in Tuesday's print edition.

Severe thunderstorms roll across much of the Northland, dropping hail and an initial round of heavy rain in many areas, including 2 inches in Floodwood. Flash flood watch continues. The News Tribune starts its severe weather live blog, which will continue on-and-off, as time allows, for the next 2½ days.

Reports start to roll in from Grand Rapids and the western Iron Range of torrential rain and street flooding as another round of storms slowly sweeps across the area.
