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 CHINOOK SALMON FINAL INSEASON SUMMARY
WEDNESDAY JULY 3
|
Chinook salmon run update: The Kenai River King salmon sonar began counting on May 16, 2019. The total estimated passage through June 30th was 4,186 large king salmon (> 75 cm mid-eye-to-tail-fork-length or ~ 34 inches in total length). The return is above the preseason forecast estimate of 3,168 large fish but remains well below the historical average. The department applies a catch-and-release mortality rate of 8% to the catch of king salmon above the sonar to generate a preliminary spawning escapement estimate of 4,173 large early-run king salmon. The optimal escapement goal of 3,900-6,600 large fish was achieved. Kenai River late-run king salmon updates will begin on July 5th. Management of the Kenai River king salmon sport fishery transitions to late-run management July 1. Emergency order (EO 2-KS-1-23-19) issued June 18, 2019 opens the July sport fishery with no bait from the mouth of the Kenai River upstream to an ADF&G regulatory marker located approximately 300 yards downstream from the mouth of Slikok Creek. From Slikok Creek upstream to the Skilak Lake general regulation applies. Please review regulations on page 50 of the 2019 Southcentral Alaska sport fishing regulation summary booklet. |

Fishery Update: Fishing success has been reported as fair to poor as water conditions have been unfavorable to sport fishing. The ADF&G creel survey and netting programs began operations on May 16. Data collected so far from these projects indicates below average CPUE’s for netting of all sizes of Chinook salmon. The creel survey indicates below average success rates for catch and release fishing on the Kenai River. Water levels continue raise and water clarity is poor which could affect angler success for this coming weekend. The preseason outlook for the 2019 early-run can be found at: |
|
Water Conditions: Water levels in the Kenai River are above average and water temperature is average. CFS at Soldotna Bridge was 17,100 on July 3. CFS at Skilak Lake Outlet was 15,700 on July 3. CFS at Cooper Landing was 10,200 on July 3. Water Temperature was 58.0 degrees Fahrenheit at the sonar site on July 3. |
