Kokanee salmon shore spawner redd locations and counts were recorded for Okanagan, Wood, Kalamalka, and Christina Lakes. The dataset combines historical counts from 1974, 1977-1980 digitized from aerial photographs and modern GPS-based counts from 2001-2009. Data was collected by Ministry staff via boat surveys, with multiple counts covering peak spawning periods for the modern years.
Use Cases
- Analyze spawning site distribution based on GPS-recorded shore spawner locations.
- Monitor population trends over time based on fish numbers recorded annually.
- Compare historical and modern spawning data based on the combined 1974-1980 and 2001-2009 datasets.
- Study peak spawning periods based on multiple counts undertaken over the entire spawning cycle.
Strengths
- Combines two distinct data sets spanning 1974-1980 and 2001-2009, providing a multi-decade view.
- Modern data (2001-2009) includes GPS-recorded locations and multiple counts covering peak spawning periods.
- Includes data from four lakes: Okanagan, Wood, Kalamalka, and Christina.
Limitations
- Historical data (1974-1980) was digitized from hand-drawn aerial photographs and may not capture peak reach counts.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
