Devils Lake Flood Forecast

Update 1: Feb 22 2010
I looks like the national weather service has slightly decreased the lake level expectation for the spring. There is now a 90 percent chance of the lake hitting 1,450.9 feet, which will likely surpass the record of 1,450.73 feet. The new prediction shows about a 35% chance that the lake will surpass 1,452, which represents a 25% drop from 60 percent three weeks ago.

I really don’t understand why they dropped the estimate. Keep in mind their predictions are just a best guess, and it is better to assume that the lake will get to at least 1,452 sometime during the summer. All it takes is one or two big snow storms or a single large rain event to completely change the model.

It appears that I was right to question lowering the expected level. NOAA has increased the expected lake level again.

We will see if the rain this week has any affect on the flood outlook for Devils Lake.   It is certainly going to put a dent in the snow pack.
