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 (>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.

Early Run Kenai River Chinook Inseason Summary for Fri. May 27

Chinook salmon run update: 

It is too early in the run to adequately interpret end of season run strength. On May 26 the daily estimated passage of Chinook salmon greater than approximately 34 inches in length was 91 fish for a season total of 356 Chinook salmon greater than 34 inches in length through May 26.

The daily estimates of total Chinook salmon passage are not yet available because few Chinook salmon and sockeye salmon have been caught by the inriver test netting project at river mile 8.6 during the month of May. The daily estimates of the total Chinook salmon passage will be posted to the web site when sufficient numbers of salmon have been captured, measured and released which is expected to be near the end of May or during early June.

Early-run sockeye salmon passage has increased slightly over recent days. Most of these fish are bound for the Upper Kenai - Russian River area.

No changes to inseason management are anticipated at this time.

The next update will be on Tuesday, May 31.

Fishery Update:

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

The news release and emergency order can be found at the following link:

http://www.adfg.alaska.gov/static/regulations/regprocess/fisheriesboard/pdfs/2015-2016/uci/2016_kenai_earlyrun_outlook.pdf

Hooligan passage at the sonar site has declined steadily this week.

Water Conditions:

Water clarity: Fair; last visibility reading 0.85 meters at the river mile 8.6 Chinook salmon test netting site.

Water flow/current: Today (7,810 ft3/sec) vs. 51 yr. Median (4,300 ft3/sec). Water discharge is above the average of 4,710 ft3/sec. for this date.

Water temperature: May 26 at sonar station 47.8°F.
