I am covering the update for Eric this week so bear with me and I’ll just hit the high points. We were able to get into San Geronimo Creek and Devil’s Gulch on Christmas Eve Day and Christmas Day and into mainstem Lagunitas Creek this week. Visibility was fair at best during the surveys so we undoubtedly missed seeing some fish, but the riffles were visible and I think we probably observed all of the redds that were present. There were live coho and new redds in all of the stream segments, but the fish we observed had wear marks, indicating that they had been in the system for a while and had not recently migrated up from Tomales Bay. We will get out when we can next week to see if the storm on Tuesday night brought in new spawners.
Since Christmas Eve Day, MMWD and National Park Service biologists have documented over 40 live coho and nine new coho redds, along with nine coho carcasses. Totals for the season are 148 live coho, 74 coho redds and 16 coho carcasses. About half of the coho and redds have been in San Geronimo Creek and about 10 percent have been in Devil’s Gulch; in both tributaries we have observed the coho nearly as far upstream as we go during our surveys.
Kent Lake started spilling on Wednesday which will make continuing surveys in mainstem Lagunitas Creek interesting, to say the least. We might not be able to get back into mainstem Lagunitas until there is a good long break in the storms. We may not get into the lowest reaches of Lagunitas at all this season.
On a side note, evidence of Santa’s sleigh crashing through Samuel P. Taylor Park was reported by Park Rangers. Must have been the punch.
Happy New Year!
