LOWER PLATTE RIVER BASIN

Week7 -Summary Ice Report

February 28, 1997
Return to warmer weather has cause dramatic changes in the river ice. The situation has greatly improved but localized ice action is still possible.

The Loup River north of Palmer (Merrick County) had an open channel with large amounts of frazil ice to include some large cakes. Water level has dropped. Much ice remained on top of sandbars. At Columbus the river was open with good channels. There was still some shore ice and ice cakes on sandbars. The Loup Power Canal was open. The confluence of the Loup and Lower Platte was open.

Downstream from Columbus the Lower Platte River was reported to have a 60% open channel. There was much floating sheet ice and some ice was piled on sandbars. At North Bend two good open channels were reported. In the Fremont area there was a good open channel from the Hwy. 77 bridge downstream. Much shore ice and floating ice were present. The rest of the river was frozen over. Below Fremont similar conditions were observed. Generally the river was considered to be open. On the Elkhorn River ice jams were present at Beemer and Wisner. From Beemer to Norfolk the river was clear. Below West Point the previously reported ice jam is still in place. This jam formed originally last November. The West Point jam had moved south of the Hwy. 32 bridge with some lowland flooding. Another ice jam was located north of the Crowell area which also had some lowland flooding. Below this point the Elkhorn was open with good flow all the way to the confluence with the Lower Platte.

Below the confluence above the Hwy. 65 area there was one open channel with much floating and shore ice. Downstream from Hwy. 6 the river was wide open to the mouth.

The Missouri River had very little floating ice. Gavins Point was releasing 34,000 cfs.
