F SUMMARY REPORT FOR January 14, 2000

Above normal temperatures have continued the melting of the ice in the Lower Platte River and tributaries. The entire river system is flowing virtually free of ice jams causing problems.

Loup River observers report approximately 30% to 50% of open channel surface occupied by floating ice and slush.

Reportings from Elkhorn River sites indicate open channels above and below bridges with moderate, melting ice accumulations at the bridges. Ice cover at Winslow and Scribner is considered to be very thin.with evidence of decay.

The Platte River at the Elkhorn/Platte confluence is reported to have 3 to 6 foot thick ice piled on sandbars with 95 per cent open channel. Other reporting sites indicate open channels of 50 to 95 per cent of open channel with ice pushed up against the banks and piled on sandbars. Much ice movement is reported to have occurred prior to this report.
