Exciting Viewing this past weekend at Leo T. Cronin

Coho salmon are now visible at the Leo T. Cronin Fish Viewing Area! This past weekend (the weekend of the 14th and 15th) we held two Creekwalks where we saw exciting coho spawning behavior at Leo T. Cronin in Lagunitas. 

On Saturday, we spotted two blue flags marking coho redds upstream of the parking lot (towards Peters Dam). No fish we spotted on the first redd, but a female coho was seen digging out her redd at the second location. It was an amazing site to see after anxiously awaiting their arrival this spawning season! On Sunday, we returned to Leo T. Cronin and checked out both of the redds again upstream of the parking lot. On the first redd, we observed 2 jacks, 1 female and 1 male. The male and female were swimming back and forth alongside each other, while the jacks darted around. At the second redd further upstream, one female was spotted just barely moving right below the flagging. The redd was easy to identify as a lighter spot just above a fallen branch.

The coho salmon spawners have returned to the Lagunitas Watershed! Let's hope for more rain and more coho to start making their journey home! Hope to see you out on the creek!

Salmon Have Returned - All Hail the Kings in Lagunitas Creek!

What a thrilling, perplexing, and joyous day it has been! Looking down on Lagunitas Creek while taking my dog Bodie on his normal morning walk on the Cross Marin Trail on my way to the SPAWN office, I see what is clearly a patch of light-colored gravel. A salmon redd??!?! It's November 18, the timing is right, but no rains have arrived. But wait, there she is, a huge female salmon moving in to take position over a compact, deep redd!

The coho are spawning! OR ARE THEY?

I contacted another biologist in the watershed leading up to the November 9-10 SPAWN Creekwalk Naturalist Training, and he had a confirmed sighting of a pair of Chinook, or king, salmon on a compact redd in the lower reach of Lagunitas Creek. Amazing! King salmon as a species are struggling - they are the most imperiled of all Pacific salmonids. They are known to spawn in Lagunitas Creek, but evidence is usually limited to seeing one or more of their compact, deep redds in the lower reached during the weeks before the arrival of our coho. This biologist sent me photo of these kings to compare with what I had seen overlooking the creek.

Armed with binoculars, the recent photos, and my identification guides, I returned to the overlook on
the old Tocaloma Bridge and gazed down on the redd. One, then two, then three salmon! The female is recognizable by the white, dead skin on her tail. The male, dead skin along his dorsal ridge. The other, small was likely a jack, and sure acted like one! The smaller jack darted in from behind, tangled in with the female on the redd, and was quickly chased off by the big male.

All of these fish were darker than coho, lacked the red color typically seen on coho when they transform to freshwater spawners, and lacked the white gums characteristic of coho. It can be tough to identify these species being so far away as to not disturb them.

All hail the Kings! The Chinook salmon have returned to spawn in Lagunitas Creek, and the coho are not far behind. This redd, and the female guarding it, have been visible the last three days. She is looking tired and likes to fade into the shadows of the undercut bank and drift to rest on a log under the bridge.

Rains have arrived, and I am heading out to hunt for any spawning coho viewable for our first Creekwalk of the season, this Saturday! To learn more about joining a naturalist-led Creekwalk and to register, click here.

See you along the creek!

Spawning season is fast approaching!



The 2013/2014 coho season is upon us! With the first hard rains in the Lagunitas Creek Watershed comes the beginning of spawning season for Coho salmon and thiier cousins Steelhead trout.. SPAWN-trained naturalists lead creekwalks to explore the majesty of the Lagunitas Creek Watershed. Join us to tour the watershed and learn all about the ecology of our endangered native population of Coho salmon. In addition, learn about native plants and animals, the natural history of the watershed, and anything else we encounter along the way.

Keep an eye on this blog for updates about great places to view spawning adult salmon as we follow them along their journey from Tomales Bay to the headwaters of the watershed.

See you out there!
