*The drop is the difference between two sucessive water level measurements. **The 2003 water levels have been adjusted upward by 0.5 m to account for a 0.5 m discrepancy in the officially reported 2003 spillway level. ***The minimum readings (as estimated from the Environment Canada graphs) include those dates that the discharge rate fell below the mandated minimum rate of 1.6 cubic metres per second until Aug 12th, and 1.2 cubic metres per second after Aug 12th when the minimum rate was lowered, as well as those dates above the minimum acceptable levels.
