By InsideOttawaValley.com, March 7, 2019 Lots of snow means lots of melt. The
Rideau Valley Conservation Authority (RVCA) reports that over 250 cm of snow has
fallen in the region to date, with no significant thaw events in between —
meaning the snow pack throughout the Rideau Valley watershed is well above
average.
Current conditions at several RVCA snow course sites are indicating near-record water content amounts in the snow for this time of year, generally not seen since the late 1970s.
(...)The RVCA reported that the two other key factors influencing actual flood conditions are precipitation and temperatures in March and April.https://www.insideottawavalley.com/news-story/9209771-rideau-valley-conservation-authority-warns-of-potential-for-above-average-spring-flooding/
