                                              The drawdown should only be initiated
                                              if the forecast for LECI4 is to exceed
                                              11.0'.  Because the drawdown creates
                                              higher than normal velocities, it can
                                              make navigation more hazardous.  Before
                                              drawdown is initiated, the Mississippi
                                              River Project Office should be notified.
