Waiting for the next wave (???)

The belted kingfisher rattled and zoomed, the varied thrush flitted, kinglets hopped --- but if there were coho at Leo Cronin today, they were invisible. Though we peered at every riffle and gravel bed, we saw no new fish, no spawning activity, no waiting males - and no spawned-out females, either.
Usually we would expect to see white-tailed females defending their redds for up to 24days after depositing eggs. Their absence is a little suspicious, given a December 13 sighting of four otters (!!!) in the spillway pool.
As for the four male coho gliding in the spillway pool since December 13, no sign. If what we're taught is true (males live nine days after fertilizing eggs), they may have died, since we saw so much spawning activity on December 9 and 11. Or maybe someone with keener eyes will still spot them; when I last saw them on December 17,  two looked pretty energetic.
MMWD is optimistic that we have not yet seen the peak of this year's migration. Me, I'm not so sure. We've had so much rain, I'm thinking there's not a lot of pent up demand, as there's been in years where the fish had to wait for storms to come in. And though the ocean conditions have been terrific, this year's coho come from the second-smallest parent class recorded on the creek -- just 67 spawners.
Sure hope I'm wrong!!!! I missed the fish jumping through the Inkwells on December 3 -- I'll be looking again after these next big storms come through.

  1. When I say second-smallest parent class recorded on the creek, I mean recorded in the Lagunitas Watershed.
