The dam consists of an earth embankment 1000 feet long and with a maximum height of 60 feet from the downstream toe. The dam forms an essentially offstream reservoir. A 20-foot-wide trapezoidal channel located along the north shoreline and abutment of the reservoir diverts the normal flow of Burgoon Run past the reservoir. The reservoir receives normal flow from the discharge of the primary spillway of Upper Kittanning Reservoir upstream, which in turn receives controlled inflow from the diversion channel. The Lower Kittanning Dam reservoir can also be fed through intake structures along the diversion channel. Lower Kittanning Dam, which is also known as Impounding Reservoir, is located in Burgoon Run Valley, about 3500 feet downstream from the tunnels under the Penn-Central Railroad Horseshoe Curve, in Logan Township, Blair County, Pennsylvania. The dam is the middle reservoir in a series of three reservoirs in Burgoon Valley and is located about three miles upstream from the city line of Altoona. It is estimated that a failure of this dam or the upstream reservoir during a flood would result in failure of the downstream reservoir and combined discharge would cause large loss of life and property damage in Altoona and further downstream.
