History, Frequency, and Processes Contributing to Ice Jams on Osoyoos Lake
Water Levels and Flows
The southern end of Osoyoos Lake and the outlet of Osoyoos Lake and Zosel Dam have become increasingly prone to ice jams in recent years. This has led to increased lake levels and decreased discharge downstream which has negatively impacted local salmon populations.
This project will complete a quantitative analysis of the frequency of ice jam events and the meteorological conditions contributing to their development. The project will analyze how temperature, wind direction, and wind speed, affect how ice jams form, persist, and dissipate at the southern end of Osoyoos Lake.
This information will be used by the International Osoyoos Lake Board of Control to determine if effects from ice jams warrant further investigations and may be used to evaluate options for engineering solutions to reduce their negative impact on the environment.
