Description: Beginning in 2015 the department will be managing Kenai Chinook runs using the ARIS sonar located at river mile 14, instead of the DIDSON sonar located at river mile 8.6. The ARIS sonar estimates will be updated twice weekly. The daily estimates represent Chinook salmon of all age and size classes. This ARIS sonar estimate is used to measure total run abundance relative to the optimum escapement goal of 5,300-9,000 early-run Chinook salmon and the sustainable escapement goal of 15,000-30,000 late-run Chinook salmon. To view daily estimates about Chinook salmon passage go to the Abundance Indices tab, which is updated as data becomes available. The inseason run summary tab will provide information about Chinook salmon passage at the mile 14 ARIS sonar site external link, netting project, creel survey, water conditions and management actions twice each week. Information about the status of the run and inseason management actions are 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 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 Kenai River Chinook Inseason Summary for Fri. Jul 22

Chinook Salmon Run Update: 

On July 21, the daily estimated passage was 490 Chinook salmon for a season total of 13,233 Chinook salmon. Through July 21, using 3 years of sonar estimates at river mile 13.7, approximately 43% of the run is estimated to have passed the sonar.

The next inseason summary will be updated Tuesday, July 26th.

Fishery Update:

Catch rates in the sport fishery continue to remain low. Since last Friday, it takes an angler on average about 20 hours to catch a king salmon. Age composition of the run has shifted towards older, larger kings salmon based on netting data and creel survey data.

Water clarity: Good; last visibility reading 0.70 meters at the river mile 8.6 netting program station; last visibility reading 1.0 meters at river mile 15.3.

Water flow/current: 17,500 ft3/sec today vs. 50 yr median (14,100 ft3/ sec). Water level is higher than the average of 14,200 ft3/ sec for this time of year.

Water temperature: July 21, 60.3°F at the river mile 14 Chinook salmon sonar station.
