Spring Melt 2021

I have started to monitor the flows and levels in our area.

Measuring water level from top of culvert at Flat Creek
Measuring flow with a velocity flow meter at the Flat Creek Culvert

It seems that the melt is occurring later than last year. As of March 25, 2021 the water flow (cubic metres/sec) at the Environment Canada Glen Alda Station is about 8 m3/s, whereas last year about this time it was twice that. This gauge, on the Crowe River, measures the combined mass flow out of Chandos and Paudash.

The ice came out early last year, (April 11) about 8 days ahead of the long term average. This year we have had a lot of rain and some warm weather which no doubt will speed up Ice-Out,

The big question always is what will the spring peak water level be. There are a lot of moving parts, but in general, the more ice/snow that can vacate the water shed early, the longer the freshet will last, and so the lower the ultimate peak level will be.
