Matawin River Gauge
The Matawin River is a tributary into the Shebandowan River that flows into the larger Kaministiquia River system, within the Great Lakes Basin. The Matawin gauge was installed in 2025 after high water events in 2022 and 2023. The gauge is used to monitor the elevation and flow through the Shebandowan River during times of high water.
