Flows in Rideau Valley to Fluctuate from Latest Weather
April 3, 2018 – Rain in the order of 20 millimetres is forecast for today and into the night that will cause water levels throughout the Rideau valley to increase beyond levels reached after rain on Saturday. How much levels increase will be limited by dropping temperatures and the changeover from rain to freezing rain or snow overnight and tomorrow. Peak flows from this weather are still expected to be less than average for the spring freshet. These may not be the actual freshet maximum flows. The Long Reach of the Rideau River, between Manotick and Kemptville, could have levels…

Below Average Spring Freshet Expected
March 29, 2018 – Barring a rain event not presently in weather forecasts, it is appearing that the spring freshet of 2018 in the Rideau valley may have already occurred on March 2 as a result of the above normal temperatures in the latter half of February that removed all of the snow. The snow that fell after the early March thaw, has gradually declined over the month with several sunny days and above freezing daily temperatures. With little snow and minor rainfall forecast, there is not expected to be enough runoff to cause significant increases in water levels in…

Spring Outlook
March 9, 2018 –The winter of 2017-18 has been one of wide variations and periods of record cold. First snow on the ground to start this winter was relatively early at the beginning of November but little more fell until after December 28 followed by the onset of the record cold temperatures including -30 degrees on January 1. After ten days of frigid temperatures, a few days of warm temperatures reduced the snow cover significantly. That warm spell ended with a flash freeze. Precipitation in all its forms and widely varying temperatures continued through January into mid-February. Since February 19,…
