Description: In 2015 the department began managing Kenai River king salmon runs using an ARIS sonar station located at river mile 14. In 2017 the Department modified the Kenai River king salmon escapement goals from goals based on king salmon of all sizes, to escapement goals based on large king salmon (fish over 34 inches) only. The early-run king salmon optimal escapement goal range is 3,900 to 6,600 large king salmon (> 34 inches). In 2020 the late-run king salmon escapement goal was modified to an optimal escapement goal range is 15,000 to 30,000 large king salmon (> 34 inches). The ARIS sonar counts found on this page are the daily and seasonal cumulative passage estimates of the number of large king salmon passing the sonar site. Additionally, the past years counts displayed on this page have been converted to large fish counts for comparison. These estimated numbers of large king salmon passing the sonar site are the primary tool for the Kenai River king salmon assessment program that also includes a sport angler harvest survey, and a netting program. The data gathered in these assessments are used together to determine king salmon run strength. This data in conjunction with Fishery Management Plans, allows fishery managers to determine if emergency order regulation changes to the fisheries are needed during the season to help ensure that the escapement goals are achieved. These abundance assessments as well as information about the status of the run and inseason management actions can be viewed via this website on the above tabs. Information is also available by telephone at (907)262-9097.

Final Early Run Kenai River Chinook Inseason Summary
KENAI RIVER EARLY-RUN KING SALMON FINAL 2022 SUMMARY
King Salmon Run Update:
The total estimated passage through June 30 was 2,051 large king salmon (> 75 cm mid-eye-to-tail-fork-length or ~ 34 inches in total length). The return is ~51% below the preseason forecast estimate of ~4,200 large fish and the historical average of 5,200 large fish. The department applies harvest and catch and release mortality estimates of king salmon above the sonar to generate a preliminary spawning escapement estimate of 2,047 large early-run king salmon and a total inriver run estimate of 2,052 large fish. The mid-point of the run occurred on June 15 which is 4 days late when compared to the historical mid-point of June 11. Preliminary age composition estimates from length groups show a low presence of 4-ocean fish (brood year 2016), making up ~14% of the run which is well below average. The predominate age classes estimated from length bins for all sized king salmon are the 3-ocean fish at ~32% and the 2-ocean fish at ~44% of the run. Post season analysis will provide further clarity of age class distribution. The run exhibited low abundance across all age classes and is preliminarily the second lowest run in the historical data set. Preliminary sport fishing harvest from creel survey which includes catch-and-release mortality was estimated to be 5 large king salmon.
Neither the optimal escapement goal (3,900 – 6,600) nor the sustainable escapement goal (2,800 – 5,600) were achieved.
