Overview


Moose Lake Weir

Alberta Environment and Parks owns and operates the Moose Lake Weir located approximately 7 km downstream of the Moose Lake outlet. The concrete weir was built in spring 1985 to improve fish and wildlife habitat, stabilize the lake level for recreation purposes, and improve the water supply storage for the nearby town of Bonnyville.

A relatively wet year in 2017 resulted in the highest recorded lake levels since 1966 and caused flooding of development and infrastructure around Moose Lake. This flooding led to concerns about Moose Lake Weir management options. A subsequent 2018 study established that removing the weir would not significantly impact water levels.

In Fall 2019, Alberta Transportation assumed responsibility for the removal of the Moose Lake Weir.

Timelines

Benefits

Removing the weir will return the Moose Lake Weir site to its natural, pre-construction state. Site naturalization is an ecologically based approach to restore non-native conditions to its previous natural condition or better.
