Focus On Flood Control

rolivelarge_1One of High Plains Weed Management’s primary objectives is flood control. Russian olive trees are shallow rooted, with a root zone rarely beyond two feet in depth. These roots do, however, extend outward past the canopy of the tree foliage. During periods of high water events, such as a 100 year flood, the trees are easily uprooted and will float downstream. Given the numbers of trees per acre, the likelihood of a major disaster is evident. When this mass of trees encounters an obstruction, such as a bridge, the flooding will cover an enormous area. The force of backed up water will eventually cause either the affected bridge to fail or the stream to cut a new channel. The resultant destruction will mean expensive replacement of bridges or the approaches to these bridges. All structures downstream will be affected in the same way.
