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.

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. Jul 13

King Salmon Run Update:

The late-run king salmon sustainable escapement goal range is 13,500 to 27,000 large king salmon (> 34 inches). On July 12, the daily estimated passage was 296 king salmon for a season total of 2,396 king salmon Historically the quarter point of the run occurs around July 17. The escapement projection for average run timing is approximately 16,500 fish. ADF&G managers will monitor sonar passage through the weekend and at that time assess whether the current management strategy of allowing fishing for king salmon without bait is still appropriate.

The next inseason summary will be updated Friday, July 20th.

Fishery Update:

Fishing effort has been low with poor catch rates continuing through the second week of the late-run fishery. The proportion of large king salmon captured in the netting program dropped mid week with mostly smaller fish reported in the inriver fishery.
