Tree Felling and Root Removal on Dam of Lake Fayetteville
FAYETTEVILLE, Ark. — The City’s Utilities Department is currently removing several sycamore trees from the Lake Fayetteville dam. Crews are reminding trail users to take an alternate route through the end of day on Friday, August 4 as the trees are being removed. The project will continue during the summer with the removal of root balls. Please use caution when in the work area and watch for personnel and equipment.
The sycamore trees pose a threat to the integrity of the dam, and therefore must be removed. The trees started as volunteers along the lake (east) side of the dam. Growth of the trees’ roots into the dam could lead to “piping” (an erosion process) failure. As water is carried through a dam, it slowly takes material from the dam core with it, threatening the structural integrity. During high water levels, the root balls of the sycamore trees are under water. If extremely high winds were to pick up during these high water levels, the trees could be blown over – causing an immediate failure of the dam. These dangers pose a risk to all people, property, homes, and businesses downstream of the dam.
The Lake Fayetteville dam is classified as a high-risk dam by the Arkansas Natural Resources Commission (ANRC). This classification is given to all dams in the state that would have a loss of human life if they were to fail. The utilities department is removing the trees to ensure the safety of the citizens downstream of the dam.
