                     LAKE SUPERIOR BOARD OF CONTROL

                                                          30 June 1997

    FOR IMMEDIATE RELEASE

                  LAKE SUPERIOR OUTFLOW CONDITIONS

    The International Lake Superior Board of Control, under authority
    granted to it by the International Joint Commission, has set the Lake
    Superior outflow to 3350 cubic metres per second (m3/s) for the month
    of July.  This is the outflow recommended by the regulation plan for
    the month of July and is about the same as the June flow.

    This flow will be released by discharging about 2080 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.  Ten gates
    will be set fully open for July at the control structure at the head
    of the St Marys Rapids including the gate that supplies the Fishery
    Remedial channel.  The ongoing repairs to two of the gates of the
    control structure are not expected to limit the outflow in July.

    During June, the water supply to Lake Superior was below average,
    while the supply to Lakes Michigan-Huron was above average.
    Currently, Lake Superior is 18 centimetres (cm) above its long-term
    average beginning of July level and about 5 cm above the level
    recorded last year.  The level of Lakes Michigan-Huron is about 56 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.

    Mr. Doug Cuthbert, Environment Canada, Burlington, Ontario is the
    Board Member for Canada. Mr. Dwight Beranek, Acting Deputy Division
    Engineer, Great Lakes and Ohio River Division, U.S. Army Corps of
    Engineers, is the Acting United States Board Member.
