The array is powered by permanent grid power with no battery backup. The site includes a remotely accessible cellular modem for data downloads and control. The site is operated year round. The system consists of five 20 ft antennas in two rows at all times, except when low flows or ice preclude water flow over some antennas. Except at extremely high flows, the entire river bed is monitored by the antenna arrays.
