The Kenai River Drainage at 2010 square miles is comparable in size to the Chehalis Basin at 2660 square miles.

Flow is glacial and varies seasonally from 1000CFS or less in the dead of winter, rising steadily to 5000-10000CFS thru May and June and peaking in the neighborhood of 14000-18000CFS in Aug-Sept.

Your guess of 100K is pretty astute, CM.

At one time the Kenai hosted runs of ER kings numbering up to 25-30K and LR kings up to 90K. It was once thought that the system on average was capable of producing consistent adult recruitment of 3:1. The early run piece was managed for a goal of 9K to produce returns of about 27K, and the late run piece was managed for as much as 30K spawners.

The keyword is WAS... as in past tense.

The lower bound of the current "large fish goals" calculated by ADFG are now 2800 and 13500 respectively ... where a large fish is roughly 20# or better.
