The Okanagan Lake kokanee shore spawner data set is comprised of two combined data sets. The historical data set for the years 1974, 77, 78, 79 and 80 and a more recent data set collected from 2001 to 2013. The historical data was derived from information collected in the field and hand drawn onto air photographs. Ministry staff circled Okanagan Lake in a boat one time each year and recorded fish numbers and spawner locations onto air photographs that were digitized in 2006 to make up the historical data set. This data set may not capture the peak reach count for these years. The data collected from 2001 to 2013 was derived from boat counts undertaken along the shoreline of Okanagan, Wood and Kalamalka Lakes. A GPS was used to record shore spawner locations and numbers. Multiple counts were undertaken over the entire spawning cycle and covered the peak spawning period for each year of data provided. The data collected for Christina Lake began in 2003 and ended in 2006. Christina Lake kokanee spawn at night in late December and early January. Kokanee spawning redd locations are available for the 2003/2004 count. Kokanee enumerations were undertaken at night for the 2004/2005 and 2005/2006 seasons and spawning redds were counted at the end of spawning cycle. For these two years there is both spawning and redd count data available.

Additional Information

Purpose

The purpose of this data is to monitor the kokanee shore spawner population in Region 8 large lakes following a dramatic decline in kokanee numbers in Okanagan Lake in the early 1990's and to provide all levels of government, regulators, consultants and others with the necessary data to protect kokanee shore spawner habitat from development pressures.
