Why is it going to be slow?  Nothing to do with the run:

Friday - drift gill nets (7 am - 7 pm)
Saturday - set & drift gill nets (9 am - 11 pm).

Why? Because: "The passage rate of sockeye salmon into the Kenai and Kasilof rivers is proceeding at a rate greater than that needed ..."

It was the same last weekend.  Odds are it'll be the same next weekend.

Great way to ruin thousands of families' fishing.  Thank you, ADF&G.
