| Abstract: | Chinook salmon (Oncorhynchus tshawytscha) passage in the Kenai River was estimated from 2017 to 2019 using adaptive resolution imaging sonar (ARIS) at river mile 13.7. Net upstream passage of Chinook salmon greater than or equal to 75 cm as measured each year by ARIS was estimated to be 7,238 (SE 250), 3,000 (SE 154), and 4,186 (SE 160), respectively, during the 2017–2019 early runs (16 May–30 June) and 22,133 (SE 452), 16,957 (SE 410), and 11,870 (SE 310), respectively, during the 2017–2019 late runs (1 July–20 August). Net upstream passage of all Chinook salmon regardless of size was estimated to be 9,696 (SE 371), 5,390 (SE 318), and 6,033 (SE 285), respectively, during the 2017–2019 early runs and 24,436 (SE 423), 25,143 (SE 654), and 18,093 (SE 547), respectively, during the 2017–2019 late runs. |
