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 new early-run king salmon optimal escapement goal range is 3,900 to 6,600 large king salmon (> 34 inches). The new late-run king salmon sustainable escapement goal range is 13,500 to 27,000 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.

Non-Sonar Tools

Late Run Netting Project CPUE Index

The Net Catch Per Unit Effort (CPUE) is an index of the numbers of Chinook salmon moving into the Kenai River and is based on the rate at which Chinook salmon are captured by the netting project conducted at river mile 8.6.


Late Run Sport CPUE Index

The Sport Catch Per Unit Effort (CPUE) is an index of the numbers of Chinook salmon in the lower Kenai River and is based on the success rate of anglers fishing downstream of the Sterling Highway Bridge Crossing in Soldotna.

Late Run Eastside Setnet CPUE Index

The Eastside Setnet Catch per Unit Effort (CPUE) is an index of the total number of late-run Kenai River Chinook salmon.

Late Run Netting Project Large Fish CPUE Index

The Net Catch Per Unit Effort (CPUE) is an index of the numbers of Chinook salmon moving into the Kenai River and is based on the rate at which Chinook salmon are captured by the netting project conducted at the sonar station located at river mile 8.6.

Late Run Kenai River Chinook Inseason Summary for Fri. Aug 18

Chinook Salmon Run Update: 

On August 17 the daily estimated passage of Chinook salmon greater than 34 inches in length was 175 Chinook salmon for a season total of 21,097 Chinook salmon greater than 34 inches in length through August 17. Approximately 99% of Chinook salmon greater than 34 inches in length have typically passed the sonar by this date.

Using mean run-timing and projected sport harvest, the current projected final escapement is approximately 20,000 Chinook salmon greater than 34 inches in length. The current sustainable escapement goal for late-run Chinook salmon greater than 34 inches in length is 13,000 – 27,000 fish.

Estimates of total run for Kenai River late-run Chinook salmon are calculated to include the sum of eastside set-net harvests, marine recreational harvests, personal use dipnet harvests, inriver sport harvests below the sonar, and passage at the sonar. The current total run projection of 28,000 Chinook salmon greater than 34 inches in length through August 14 is below the preseason forecast of 33,000 fish.

The final late-run summary will be posted at the end of August.

Fishery Update:

The sport fishery for Chinook salmon ended on Monday, July 31. Chinook salmon captured in the netting program recently have been primarily older (larger) Chinook salmon.
