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.

Early 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.

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.

No changes to inseason management are anticipated at this time.

The next update will be on Friday, May 29.

Fishery Update:

Fishing for Chinook salmon is closed at this time by emergency order.
