PROJECT ALERT NOTICE (ND) Flooding in northeastern North Dakota

Date: Tue, 21 May 2013 16:19:38 EDT

Summary: Heavy precipitation results in near record flooding in northeastern North Dakota

Major flooding is occurring at at three locations in northeast North Dakota. The flooding is the result of three days of state-wide rainfall with upwards of 5 inches in places. The dry soils throughout the state mitigated most of the impacts, with most gage locations experiencing minor flooding.

The three locations, Little South Pembina River nr Walhalla (05099400), the Pembina River at Walhalla (05099600) and the Tongue River at Akra, all located in the northeast part of the state, are experiencing record or near record flooding. All three locations have an AEP in the .04 to .02 range.

A rapid deployment gage (RDG) has been installed on Lake Renwick (right upstream of the Akra gage) so the state and local emergency managers can monitor the record water levels in the lake.
