Juvenile Salmonid Movement and Habitat Data from Strait of Juan de Fuca Watersheds

The Strait of Juan de Fuca Intensively Monitored Watershed program, led by NOAA, began in 2004 to test watershed-scale responses of steelhead and coho salmon to restoration. Data includes PIT tagging records with fish weight, length, and location, alongside habitat measurements like wood and stream surveys from treatment and control watersheds in Washington State. Preliminary results suggest increases in pool habitat and fish populations, with monitoring ongoing to determine long-term response.

Use Cases

• Modeling juvenile salmonid survival and movement patterns based on PIT tag data.
• Assessing the impact of restoration treatments like LWD placement on habitat metrics.
• Analyzing watershed-scale fish population responses to restoration over time.
• Investigating life history traits such as stream swapping and outmigration timing mentioned in the description.

Strengths

• Long-term monitoring program initiated in 2004, with some smolt and adult data dating back to 1998.
• Includes data from two treatment watersheds (East Twin River, Deep Creek) and one control watershed (West Twin River).
• Data collection follows established EPA EMAP site selection and sampling protocols.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in PDF format, which may complicate automated analysis.
