1914- Weir Installation & Upgrades

“A control structure was built by the federal government in 1914, on the outlet of Pigeon Lake at Pigeon Lake Creek and was rebuilt in 1939/1940. The weir regulated the flow through Pigeon Lake Creek during the summer to prevent the flooding of hay fields. In 1981, the lake level fell after the outlet structure and creek channel were cleared and maintained. In 1986, Alberta Environment replaced the old weir with a new two-bay structure with two stop logs and a Denil 2 fish ladder. The weir is usually operated with one stop in place to maintain the lake level at an elevation of 40.05m. Between 1972-1987, the water level fluctuated over a range of about 1 m., typical for many lakes in central Alberta.
