Adobe Creek Restoration
A Conversation with
The Adobe Creek
Restoration Project was started 13 years ago in Cas
Grande High School of Petaluma, California. Through
the efforts of high school students, this once dead
creek and ecosystem has been brought back to life.
Jennie Furrer shares the impact working on this
project has had on her life.
InSite: How did you get involved in this project?
Jennie: Well, Tom Furrer, a science teacher who
started this project 13 years ago, is my uncle. So ever
since kindergarten I've seen it grow. It has just encouraged
me and enhanced my life so I became a part of it when I was
a junior in high school.
TI: How old are you now?
Jennie: I'm 18 years old.
TI: How did it get started?
Jennie: A group of kids in 1983 were learning
about endangered species in one of Mr. Furrer's wild life
classes. They did some research and they found that a creek
right across the street from our school used to have Steel
Head Trout running back and forth from the sea every year,
to spawn. But for 100 years the water was diverted from the
creek, so basically all life in the creek died. And the
creek was declared dead. So the kids decided they wanted to
do something about it. They went in and pulled out all the
garbage. At least 10 truckloads of garbage. Everything from
a dishwasher to tires. It was really gross. Then they
planted trees. About 1,100 each year.
creek was declared dead.
So the kids decided they
wanted to do something about it.
TI: How long is this creek?
Jennie: Seven miles. Some of it is on private
property. But when the creek comes to the old Adobe
[General Vallejo's former home], that's a historical
state park, so from that point on [about 5 miles]
that's where we did all of the restoration.
So what have you guys accomplished in the past 13 years?
Jennie: A lot! From having no fish in the creek we
had 60 Steel Head Trout come back last year. Right now we
have little baby Steel Head all through our system. We also
took on a project in 1993 working with Chinook Salmon. They
come down the Petaluma River and they would normally go into
Adobe Creek but at the time of year they come [in the
fall] the creek doesn't have any water in it. So now
when they come down the river we've set up big, long
containment nets and go catch the salmon.
Jennie: Because they come down the Petaluma River
and die before they get a chance to spawn because the waters
are too warm and it doesn't provide enough oxygen for
TI: So you lift them out and bring them where?
Jennie: First we put them into our truck which has
a tank with oxygenated water in it. Then we bring them to
our hatchery. From that point we point them into our four
"raceways." Then we'll check them to see if the females are
ready to give their eggs and the males their sperm. Once
they're both ready to do that then we'll do an "egg take."
And that's combining the eggs and the sperm to form a zygote
[fertilized salmon egg].
TI: How long do you keep the salmon before they are
ready for this process?
Jennie: Well, because they've just come back from
the sea when we bring them in, it will only be a day or two
before they're ready. Salmon only spawn once in their life
and then they die, so when we bring them in they are all
deteriorating in our hatchery. Once they're ready we'll put
them down because it's more ethical to them and it's easier
on us to be able to perform the egg take.
only spawn once in their life and then they
What do you mean by "put them down?"
Jennie: We kill them. But we kill them instantly
so it's not like really disgusting. And they are going to
die anyway as soon as they spawn.
TI: So even though the fish is dead you can still take
the egg and sperm from them?
TI: What do you do with all of these dead
Jennie: We have a permit with Fish and Game. We
put them in a freezer until a certain time period and then
we put them back into the Petaluma River. Because in nature,
when the parent fish spawn and die and the babies get big
enough to need some kind of food source, they will eat the
bodies of their dead parents. So it's kind of a food chain
kind of thing.
TI: So meanwhile, back at the hatchery, what do you do
with the fertilized eggs?
Jennie: We put them in our incubation trays. We
have 32 trays, so we put about 1,000 in each tray and they
stay in there for about a month. They go through the egg
stage, then they "eye up."
TI: What does that mean?
Jennie: They get a little black dot in their
little red egg. And that's a sign of their eye. From that
stage they grow into a fish form and they'll get a yolk
sack, kinda like an umbilical chord and they eat that. After
they eat that we put them into our trough because they need
to rely on another food source. And that's when we hand feed
And then you release them back into the ocean?
Jennie: Yeah. We currently have about 4,000 in our
hatchery. Then right before summer, actually this year we
are releasing them on May 22nd, we will put them right
underneath the Golden Gate Bridge.
currently have about 4,000 [fish] in our
hatchery... we will put them right underneath the Golden
TI: How big are they when you release them?
Jennie: About 5 inches long.
TI: Are they in danger of being eaten by other fish?
Jennie: They do have a chance of being eaten... we
haven't really done any research on it, but I think they are
TI: So you guys are working with two different kinds
of fish. Tell me more about the Steel Head Trout?
Jennie: That's a separate thing from the Chinook
Salmon. Like I said, the salmon would come up Adobe Creek
but they can't because there's no water. But now the creek
is starting to replenish its water so hopefully we'll have
water in it year-round.
TI: Doesn't the creek's water level depend on
Jennie: Yeah, but it's also because the water has
been diverted [to the city of Petaluma]. But two
years ago we got the water diversions knocked down because
they were on an earthquake fault.
TI: What are water diversions?
Jennie: For 100 years Petaluma has relied on Adobe
Creek for their water source for the town. But they found
that it was only providing 2 percent of the city's water, it
was like a hopeless cause. And 7 percent was drying up
through evaporation, so they kind of gave up on it. So we
knocked down the water diversions, and now the creek is able
to run free. And the water can come down from the mountain
and is able to stay in the whole system.
100 years Petaluma has relied on Adobe Creek for their
TI: What purpose do the trees you've planted
Jennie: We planted Willows because they grow
really quick and they reproduce really fast. They serve as a
canopy so once they grow over the water they provide shade
and the water won't evaporate as quickly.
TI: These trees probably create a place for land
animals to live too.
Jennie: Yes! Since we've been in there we've
basically created a whole new kind of ecosystem,
because all the life can come back. Birds can build nests in
the trees and lay eggs. There are now a lot of tadpoles in
our system, which is really neat to see. Everything is
coming back because of our efforts.
TI: How many students are currently involved in this
Jennie: About 20. The reason we keep it smaller
than a normal class is because it's really hard for our
advisor to keep watch over more than that number. Also when
it's small we get to know each other better and it's a
better working atmosphere for all of us.
So this is a regular class that you're taking along with
say, Math and French?
Jennie: Yes. It's called Field Studies. It's a
class but it's also a club and you have to work to get in.
You sign up in whatever year you want to take it. Often
times we have only juniors and seniors in our group but we
will have a sophomore or a freshman if they show a strong
desire for the group. They'll fill out an application, then
they'll go through an interview process with our current
members. Then once they've done that they'll have to do some
work over the summer, like on the landscaping and the
hatchery. Then when they come back to school that next year
they go through all the lessons - learn about the fish, our
history, and the creek. Then once they pass three tests on
all those things, 100%, they go through a check list of
certain things that they have to accomplish. Once they have
done all of that and they are approved by our advisors then
they officially become United Anglers.
TI: It sounds like this is a commitment.
Jennie: Oh yeah! We try to get the kids who show
the most love for it because we do a lot of the stuff on the
weekends. So the kids have to be willing to give up their
free time to come help this project. As long as they show a
love for the group year after year and prove they can do it,
they can take the class as long as they want.

TI: You said you are 18. When you go to college are
you going to continue studying about the
Jennie: Yeah, I want to be a teacher but I also
want to work with animals in some way so I'm thinking,
environmental education, or something like that.
TI: It sounds like this whole project has really
influenced your life.
Jennie: It changes almost everyone who comes
through this group. You not only become better able to work
with animals but they become a better person. They become
associated with a lot of people in the community. It's a
wonderful thing because to see something actually change in
front of your face. Something that wasn't there come back to
where it once was.
TI: Isn't part of your goal to inspire other student
groups around the world to take this kind of active interest
in their own environment?
Jennie: Different groups call us for advice.
Basically we tell them that they can do it if they are
willing to put in the time. In our own area, there's another
hatchery called Warm Springs Dam, and because of the
interest in the environment and fish that we've brought into
our community a lot of elementary school classes are taking
in salmon eggs and Steel Head Trout eggs into their
classrooms in their own little aquariums and raising them.
That's something that has happened because of us.
TI: So you guys are learning and doing something that
is making a difference.
Jennie: And you also get to meet people that you
would never think you would get to be friends with. But you
become really close, kinda like a family. So it's a lot of
fun because you get to be with them a lot.
TI: Well, it sounds like, even though there might be
lots of differences, what you all have in common is the
desire to work on this project and see that you can actually
Jennie: We have a saying, "Keep the dream alive."
Basically it's a dream that we're going to make a difference
in this community if we keep trying and keep educating. If
we just keep trying and making a difference then we'll be
able to change the world.
