Finally!! Back from that field trip and what a doozy it was!! Remember I was telling you about that " been there done that " feeling? Well we recently took a field trip to the Feather River Fish Hatchery (yes still here in Oroville, CA.) We've been to the fish hatchery before, a few years back in the Fall when the Salmon were running, but this time was very different.
The populations of Chinook returning up the Feather River to spawn in the Fall are phenomenal and the season lasts from September through November. During that time the hatchery maintains spawning facilities for somewhere between 9,000 to 18,000 Salmon -- this process produces, on average 18 to 20 million eggs -- Yes I said MILLION!! Can you imagine?? This hatchery is an essential part of maintaining the sport fishing for the Feather and Sacramento Rivers, AND even contributes to the commercial and sport fishing in the Pacific Ocean.
This time of year Steelhead are running!! So our visit to the fish hatchery was quite a bit calmer than the last time we visited. Steelhead populations are quite a bit smaller and the run is a shorter period of time, typically December through January. We had a great "tour" guide, Jana, from the State of California Department of Resources (DWR). (The DWR was where I called to inquire about tours/field trips, by the way -- a tidbit that might be noteworthy for your 'resource list' -- just sayin'!...)
As we stood at the viewing window above the spawning area we learned that Steelhead don't die when they spawn, as the Chinook do. Thus the spawning process involved is much different. Some of you may know that since the Chinook spawn at the end of their life cycle, the hatchery will anesthetize prior to, then humanely euthanize the fish following collection of, the eggs and milt needed for spawning.
[SPECIAL NOTE: Jana shared with us that the meat of the Chinook is not wasted. It is used through a local program to feed homeless and low income in Butte County. We thought this was a great community service, and were glad that she shared that tidbit. -- I don't remember that being shared on our previous trip here. Ahh... another perk of a personal family tour.]
So, back to the Steelhead -- the hatchery worker will introduce the fish into water with higher carbon dioxide to slow down their movement. The females are then injected with air in order to release the eggs into a tub -- she is then released back into a holding tank until her movement is normal and then released through a shoot back into the river. As soon as the eggs are expressed from the female, the milt is released from the male into the same bucket and the male is released through the same shoot.
Jana noted that the eggs and milt are mixed quickly and then put into trays and taken to a specially equipped room to be diligently cared for until hatching. The "nursery" for caring for these fish is amazing! The record keeping alone is a quite a task, not to mention maintaining water temperatures and tracking each tray for growth, including removal of eggs that fail to thrive.
Even though the Steelhead population is smaller, they still spawn approximately 2,000 fish each year. Then the eggs are cared for at the various stages of development, including spending a time in "raceways" as they progress through the stages of "Fry" -- "Fingerlings" -- then "Yearlings" -- It takes many months until they are large enough to be transported via special fish tanker trucks to the San Francisco Bay Delta.
If you'd like to see some video about this I encourage you to visit YouTube and search "Feather River Fish Hatchery" -- You'll see some great video of the fish ladders and get a feel for the numbers and sizes of fish that travel back up the Feather River each year. It is really amazing to think that the Chinook make the trip from Oroville, at the Feather River Hatchery, down to the San Francisco Bay (and beyond -- some reports as far as Alaska and even Japan!! -- ) and then back again in their life cycle, which averages three to four years.
It is absolutely ASTOUNDING to think that the Steelhead may make a similar journey several times in their life span of six to nine years; during their life they may spawn between two to four times, on average. That may not sound like much, but if you take time to look at a map and find Oroville, CA (north of Sacramento and just SE of Chico) then find and follow the Feather River down through the Sacramento River and on to the San Francisco Bay -- Wow!! And then... think about their ocean travels?? An amazing feat for a fish less than two feet long, don't you think?
One more side note -- I mentioned earlier about searching YouTube for the Feather River Fish Hatchery, and that one of them shows the "fish ladders". Now there's a term that conjures up mental images akin to a Dr. Seuss drawing, huh? Well, they're not what you think... the fish don't get out of the water and go vertical! Geesh! Some people... tee hee hee...
The fish ladders were built as a means for the fish to traverse the river that has been impacted by the Oroville Dam (more about the Dam will be in a later blog -- perhaps the next one...?? ) You see, fish in the Salmon family carry genetic markers for where they were born... that is how they navigate their way back to their birthplace for spawning. Since the placement of the Oroville Dam in the late 1960's has made that rather challenging, the State Water Project incorporated the fish ladders to aid this natural process.
While we didn't take any pictures of the eggs and milt being expressed I did see quite a few cool videos on YouTube, but not sure if I can post without permission -- So I hope you will take time to look up the Feather River Fish Hatchery, Oroville, CA and enjoy the videos. Until next time...
Enjoy the journey...

Been There! Done That! ... Or???
I'm trying not to feel frustrated about not posting already, as we HAVE been busy planning field trips and more! AND ... we have been sick like so many of our friends this time of year. Glad we're in such good company <<GRIN>>. Guess at least we're thankful for the internet and being able to put our "down" time to good use = RESEARCH!
Over the past several weeks we have been visiting family in Northern California. An interesting, or perhaps challenging, perspective of considering what to 'See and Do' in this area is that not only have we been visiting in this same area over the past twelve years, we lived here for two years and... it has strong parallels to the area where I grew up, some 70 or so miles Southeast.
Oroville, translated: "City of Gold" is in the Northern Sacramento Valley and was established during the California Gold Rush of 1849. The parallels to my hometown of Folsom (also in the Sacramento Valley) are 'Amazing!' Not only were both founded during the Gold Rush, but both are river towns, both had significant Chinese settlements and seemingly grew from virtually nothing in a short period of time due to the influx of "prospectors" seeking their fortunes!!
Both cities not only embrace their heritage in California Gold Rush history, but both have significant railroad history as well and are sites of earthen filled dams that provide hydroelectric power to the Golden State. Lake Oroville and Folsom Lake are both known far and wide for their multitude of recreational activities just to add another dimension to this brief comparison.
Thus the aforementioned 'familiarities' to not only Oroville, but Butte County, has made me -- and us -- rather complacent about considering what there is to 'See and Do'. It kind of feels like "Been there, Done that!" If you know what I mean... Perhaps you can relate? Do you have places that you have visited on more than one occasion and thus feel like you've pretty much seen it all?
I decided to get back to my roots, so to speak. I learned at an early age about this wonderful place in our town (almost as awesome as the library... which of course is also a good resource for seeking info...) it was called the "Chamber of Commerce"! Our Chamber of Commerce was a plethora of information about what to see and do, along with little known facts and trivia, about our town! So a few days ago... off to the Oroville Chamber of Commerce I went!!
I came home with a handful of brochures about the area that were very helpful to get us started on planning our adventures. One really cool book is filled with "101 Things to do..." A few brochures provided resources on 'self guided tours' -- one of Murals -- one called the Greenline Tour, that meanders through town and up to the Oroville Dam -- and another that we found especially enjoyable (thus was our first adventure...) was labeled as a "Walking Tour" but beings as the high for the day was in the 40's we opted to drive and stop at each point on the map.
The tour probably covered a couple of square miles and had us stopping at historic points of interest. Ian and I (Rich stayed at the trailer as he was sick) simply used our cell phone, dialed a number and punched in three digits as they appeared on the brochure. Voila!! A short story about the site available at our fingertips! Great idea!! Kudos to whomever came up with THAT idea!! Loved it!! Basically you're dialing into a phone system and punching in an extension, so it's possible to dial in from anywhere and hear the information again -- which I intend to do about one site, in particular, that I'd like to do more research on -- but we'll save that for another day!
After our 'driving version' of the Walking Tour, Ian and I went on a hunt to locate some of the many murals around town! They were great fun and gave us a glimpse into the multifaceted history of this little "City of Gold"! The following day we followed it up with another resource trip: The local branch of the Butte County Library, and a visit with our favorite Librarian -- Heidi!
So... There ya go!! That's where we started... and over the next few weeks we'll share with you a bit of what there is to 'See and Do' in Oroville, CA (and perhaps the surrounding area of Butte County -- we haven't decided just how far we'll go yet...) Along the way we will also share with you where we found more resources to determine our 'See and Do' list. Perhaps you'll discover new appeal to visiting places that you've been before! And as always... We hope that you too, will...
Enjoy the journey....
