Planning for 2022 salmon monitoring program is underway

Preparations for the 2022 Big Bar salmon monitoring program are underway, with the team incorporating their experience from the last three years of fish passage assessments conducted at the slide site.

Crews responsible for collecting the monitoring data are gearing up for the installation of sonar equipment in early June at the Alfalfa station, near the Big Bar ferry, and another site at Churn Creek. They will also focus their radio tag applications on vulnerable Spring 52 Chinook and early-timed Early Stuart, Bowron and Taseko sockeye. These salmon have a greater likelihood of being delayed at the slide site if there are high water flow conditions in the Fraser River this year.

The Upper Fraser Fisheries Conservation Alliance (UFFCA) will continue with telemetry monitoring in the Upper Fraser watershed until the end of the 2022 migration in November.

Throughout the season, crews will track fish movement to determine at which water volumes those fish can migrate upstream through the canyon without delay. Compass Resource Management Ltd., the consultant leading the structured decision making process, will incorporate this data into its research as work continues to develop a long-term solution for restoring fish passage at Big Bar.
