This set of graphics includes historical data on the environment of the Sylvan Lake watershed and surrounding Central Alberta. The quality and quantity of water in the watershed are critical factors that determine watershed value. Dissolved and suspended minerals and organics from the land are transported in surface and underground water into the lake and …

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 …
