When we install pond levelers to help reduce beaver-related flooding, we also place staff gauges up and downstream of the beaver dam to monitor water levels.
By tracking water levels on either side of the dam, we can assess how well the pond leveler is functioning while also monitoring the ability of fish (especially salmon) to safely navigate past the device during spawning season. To ensure these measurements are meaningful over time, we survey the elevation of each staff gauge when it’s installed, tying water level readings to a consistent elevation reference.
This monitoring work is an important part of balancing beaver coexistence and healthy fish populations in the Snoqualmie Valley!
