       LAKE SUPERIOR OUTFLOW TO DECREASE
    >
    The International Lake Superior Board of Control, under authority
    granted to it by the International Joint Commission, has set the Lake
    Superior outflow to 1980 cubic metres per second (m3/s) for the month
    of September.  This is the outflow recommended by the regulation plan
    for the month of September and is a reduction from the August outflow
    of 2680 m3/s.
    >
    This flow will be released by discharging about 1844 m3/s through the
    three hydropower plants and passing most of the remaining flow through
    the control structure at the head of the St Marys Rapids.  The number
    of gates open at the control structure will be reduced from the August
    setting of four gates fully open to the equivalent of one gate half
    open for September.  There will be no change to the setting of gate #1
    that supplies the Fishery Remedial Works.
    >
    During August, the water supply to Lake Superior was well below average
    while the water supply to Lakes Michigan-Huron was above average.
    Currently, Lake Superior is 8 centimetres (cm) above its long-term
    average beginning of September level and about 13 cm below the level
    recorded last year.  The level of Lakes Michigan-Huron is about 58 cm
    above its long-term average level and about 34 cm above the level of a
    year ago.  The Board will continue to monitor conditions on Lake
    Superior and downstream and will advise the International Joint
    Commission accordingly.
