Dredging the Marina Bay Channel

Sylvan Lake Precipitation 2018
This graph shows the precipitation history recorded by the Alberta Agriculture weather station at Hespero, west of Sylvan Lake from Jan 1 to November 13, 2018. The shortfall is 170 mm (0.17 m) of precipitation compared to the long term average. We assume that those observations at Hespero are representative of those for our watershed …

Without significant precipitation and tributary discharge from watershed land into the lake through the summer months, about 10.92 million tonnes of water disappeared by evaporation from the lake surface. That is why the lake level dropped by about 0.26 …
