Surveying & Monitoring
Winter Steelhead Surveying
In the winter of 2019 and 2020, CWC conducted winter steelhead redd surveys to create a baseline of adult escapement from 2 different cohorts of fish – and to collect summer water temperature data through the deployment of temperature loggers.
The project occurred on the Upper Calapooia River, between the Holley Bridge (USGS RM 45.5) and the perceived end of anadromy for salmonids (USGS RM 72.9).
Historically, the Calapooia River marked the upper end of winter steelhead distribution in the Willamette Basin, and a spawning tributary for spring chinook. These are both DPS/ESU listed species, and little is known about their distribution and life history in the Calapooia River.
