Significant Ice Jamming Occurring Near Lewellen
on the North Platte River

 

Significant ice jamming is occurring near Lewellen, on the North Platte River.  The main ice jam is located about one mile south of Lewellen, on the County Road 199 bridge.  This has been confirmed by two National Weather Service employees who were performing survey work on Friday morning, December 8th.

The river stage at Lewellen at 1100 AM CST was 8.70 feet.  Flood stage on the North Platte River at Lewellen is 7.5 feet.  Earlier this summer when the river stage was around this level, County Road 199A experienced some washouts as a result of the river being so high.  A section of County Road 199A between Lewellen and the North Platte River has washed out as a result of the recent ice jamming.

A flood warning has been isssued for the ice jams that have formed along the North Platte River between Lewellen and Lake McConaughy.  As cold temperatures remain in the forecast for the next several days, the ice jam is not expected to break up, so some flooding is possible to continue throughout the weekend.  Remember that ice jams can cause rapid fluctuations in river levels as the ice jam forms, then releases - and redevelops.
