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.

Early Run ARIS Threshold (>34 in. total) Sonar Estimate

The ARIS threshold estimate is an estimate for fish targets that are measured to be 34 inches or greater in total length. These estimates are a daily index of the relative abundance of Chinook salmon passage past the mile 14 ARIS sonar site.

Early 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.


Early 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.

Early Run Kenai River Chinook Inseason Summary for Fri. Jun 24

Chinook salmon run update: 

On June 23 the daily estimated passage of total Chinook salmon was 256 fish for a season total passage of 8,130 Chinook salmon of all sizes. For the 3 years data is available about 82% of the run has migrated past the river mile 14 sonar by June 23. Chinook salmon stocks in Cook Inlet are again showing early-timing in 2016 and are likely returning to Cook Inlet streams in a similar or earlier timing pattern that was observed in 2015.

Beginning Saturday, June 18 a limited area of the Kenai River opened to harvest of king salmon under existing regulations while the catch and release fishing continued in most of the Kenai River. No further inseason management actions are anticipated for the early run at this time.

Beginning Friday, July 1st through Sunday, July 31st, bait/scent will be prohibited in the Kenai River from its mouth upstream to markers located at the outlet of Skilak Lake.

The next update will be on Tuesday, June 28.

Fishery Update:

Catch rates have been very low recently because of bad water conditions. Catch rates have varied each day since fishing began June 4, however since July 19 the creel survey has yet to interview any anglers that have caught a king salmon.

Water Conditions:

Water clarity: low, turbid; last visibility reading 0.47 meters at river mile 15, and 0.43 meters at the river mile 8.6 Chinook salmon test netting site.

Water flow/current: Today (16,400 ft3/sec) vs. 51 yr. Median (10,200 ft3/sec). Water discharge is considerably above the average of 10,600 ft3/sec. for this date.

Water temperature: June 23 at sonar station 53.2°F.
