Lake Sakakawea Declared Ice-Free

RIVERDALE, N.D. (AP) — Lake Sakakawea was declared ice free this past Sunday, making for one of the shortest seasons ever from freeze-up to open water.

The Army Corps of Engineers says the official ice-free observation came at 2:30 p.m. Sunday.

The Missouri River reservoir was declared frozen over Jan. 6. The April 12 ice-free designation means the lake was officially frozen over for just 99 days, the sixth-shortest amount of time since lake history began in 1961.
