OKC - Okanagan Channel at VDS-3

The OKC site is located in the Okanagan (Canadian spelling) Channel at 310th Avenue/Road 18 upstream from Osoyoos Lake. The river in this section is channelized and Vertical Drop Structures (n=17) are used to control the river gradient. The array is located approximately 130 ft downstream of VDS-3. The river at this location is approximately 80 ft wide, enabling nearly full coverage of the width with four 20-ft antennas. Detection of adult sockeye salmon (Oncorhynchus nerka) is the primary focus of the array. Water depth during the sockeye salmon migration ranges from 10 to 24 inches. Optimal read range of 12-mm TX1411SST PIT tags in pass-by orientation ranges between 18 and 20 inches resulting in high detection efficiency. Four new antennas were added to the site in a second array in March 2017.
