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 2013 and 2014 data provided below are ARIS sonar estimates from rm 14. 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 ARIS Threshold (>30 in.) Sonar Estimate

The ARIS threshold estimate is an estimate for fish targets that are measured to be 750 millimeters (30 inches) or greater in METF length. These estimates are a daily index of the relative abundance of Chinook salmon passage past the mile 14 ARIS sonar site.

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 Thu. Jul 2

Chinook Salmon Run Update: 

On July 1, the first day of the late-run Chinook salmon assessment, the daily estimated passage was 186 Chinook salmon for a season total of 186 Chinook salmon.

The next update for the sonar passage estimate is Tuesday, July 7. The next complete inseason summary will be updated Wednesday, July 8th.

Fishery Update:

Fishing effort and catch rates were low for the first day of the late-run fishery. Chinook salmon captured in the netting program on July 1 were primarily younger, smaller Chinook salmon.

Starting July 1, fishing for Chinook salmon is allowed with restrictions in both the Kenai and Kasilof rivers and can be found in the emergency orders below:

Water Conditions:

Water clarity: Poor; last visibility reading 0.45 meters at the river mile 8.6 netting program station. Fair above tidal influence; last visibility reading 0.73 meters at river mile 15.3.

Water flow/current: 14,300 ft3/sec today vs. 50 yr median (11,700 ft3/ sec). Water level is higher than the average of 11,800 ft3/ sec for this time of year.

Water temperature: July 1, 54.5°F at the river mile 14 Chinook salmon sonar station.
