Coho salmon are currently spawning throughout Lagunitas Creek, albeit in below-average numbers. We observed 21 coho salmon and 11 new redds this week (see table of MMWD salmonid observations so far this season). The most upstream of these fish were two coho on a redd upstream of the Leo T. Cronin Fish Viewing Area, about as far upstream as salmon can go in the creek. These fish likely migrated upstream following the small storm we received last week. We expect coho spawning activity to increase slowly but remain below average while the dry weather continues.
Chinook salmon observations have declined over the last few weeks, with only one Chinook and one Chinook redd observed this week. We may see another pulse of Chinook if/when the rain returns. The extended weather forecast is for dry conditions to continue for the next two weeks.
I’ve included a photo of one of the coho redds we observed this week. The contrast between the light-colored redd and the dark, undisturbed streambed, plus the extraordinarily clear water, make this redd unusually easy to identify. Upwards of 2,000 salmon eggs are likely buried in the upper right portion of this redd.
