Creek Cleanup for the Salmon Was a Success
Since salmon need clean water both to live in and
reproduce, we cleaned up an area of
Walnut Creek where salmon usually come to spawn. Because of the
homeless camps nearby, there were a lot of large objects like grocery
carts, old clothing, and luggage, along with a lot of cigarette butts
and fragments of packaging. We didn't see a single plastic bag,
however. We were not able to remove all the trash, but it's a lot
cleaner than it was and we'll return next year.
Creek Restoration Project Continues in Civic Park Dec. 10
our Saturday, December 10 workday, we'll finish cleaning up our planting site and plant a few early things. No
experience is required -- just a desire to make the creek a better
for both humans and wildlife. Join us for some rewarding work, camaraderie, and a
brief talk about an aspect of the work we're doing.

New LAFCO Open Space Policy
LAFCO, a powerful county agency that
regulates growth and development, recently adopted a new policy that
governs conditions under which agricultural and open space lands can be
converted to urban uses. We argued for a strong policy as a way
of keeping watersheds from being further fragmented. While the
policy does not require mitigation as we would have liked, it is a lot
stronger than it started out. It will be reviewed in a year and
can be further strengthened then if need be.
Community Service Day Projects
Friends of the Creeks sponsored two projects on
Community Service Day this year -- a cleanup on Pine Creek, and for
the more restoration minded, ivy removal in San Ramon Creek near
Creekside Drive downtown. The Flood Control District sponsored a second Pine Creek cleanup.
Investigating Fish Habitat
As part of our ongoing project to learn more about the
fish in our creeks -- both what species we have and where they live --
we asked Gretchen Hayes, a geomorphologist, to teach us how to do
pebble counts. This is a technique for assessing the quality of gravel
beds for suitability as redds (the nests salmon build to lay their
eggs). After locating a promising spot, we laid out a
grid, took a sample pebble from each intersection, and measured and
recorded it to get a histogram of gravel sizes.
an experiment, we used sandbags to divert all the flow of San Ramon
Creek from the bypass into the natural channel during the dry season to
see whether it
made a difference in the water temperature. There wasn't enough
extra water to make a difference, but we'll try again early next summer
when there is more water (and more baby fish).
Other Recent Activities
A group removed arundo from a stretch of creek bank below the Creekwalk
in Civic Park East on August 14. A second group worked on Las Trampas Creek in September. Slowly but surely, we are making
progress against this invasive weed.
