2017 Run and Forecast
In 2017, the commercial harvest of sockeye salmon in UCI (1.8 million) was 0.1 million greater than the preseason forecast of 1.7 million. In 2017, the estimated total run was 2.9 million to the Kenai River; 817,000 to the Kasilof River; 306,000 to the Susitna River; and 83,000 to Fish Creek. The 2017 run forecast was 2.2 million to the Kenai River; 825,000 to the Kasilof River; 366,000 to the Susitna River; and 75,000 to Fish Creek. Overall, the 2017 sockeye salmon run (4.6 million) was 15% above forecast (4.0 million), largely due to the above forecast Kenai River sockeye salmon run.
In 2018, a run of approximately 4.6 million sockeye salmon is forecasted to return to UCI with a commercial harvest of 1.9 million. The forecasted commercial harvest in 2018 is 0.9 million less than the 20-year average harvest. The run forecast for the Kenai River is approximately 2.5 million, which is 1.1 million less than the 20-year average run of 3.6 million.
