Bow River Basin - Water Supply Forecasts

As of March 1, 2004, below-average to much-below-average natural runoff volumes are forecast for the March to September 2004 period in the Bow River basin (Table 4). Current runoff volume forecasts range from 77 to 89% of average, 4 to 7% lower than last month's forecasted volumes. Current March to September 2004 volume forecasts are 1 to 6% higher than runoff volumes recorded during the same period last year, except for the Cascade Reservoir, which is forecast to receive 10% less volume than last year. Current forecasted volumes for the March to September 2004 period for the Bow River at Calgary would rank 24th lowest in 91 years of record (1912-2001).
