ATTENTION: The level of Norfork Lake has fallen low enough that the siphon cannot be operated safely.
           Minimum flow will be released by using a low setting on one of the hydropower units.
           Water levels downstream should be comparable between siphon releases versus turbine releases.
           Siphon operation will be tested when the lake level rises above EL. 548 feet.
