Cleanup for the Salmon This Saturday, October 29
Salmon need clean water both to live in and lay their
eggs. On Saturday from 9:00-noon we will be cleaning up an area of
Walnut Creek where salmon usually come to spawn. Register here.
Creek Restoration Project Continues in Civic Park Nov. 12
our November 12 workday, we'll clean up this year's planting site to get it ready for the new plants. We'll also remove some nearby weeds. 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.

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.
Native Walnut Project: In
June 2015 we
raised $10,000 to sample candidate walnut trees to see whether they
were genetically pure native trees. As of August 2016
preliminary results show that well over half the samples are
native. The next step is to see if we can grow them from cuttings so we and other groups can use them in restoration projects. Read the details here.
Annual Creek Cleanup -- Thank you!
Over 360 volunteers participated in this year's downtown creek cleanup. We are overwhelmed by your response!
Once again, we removed a total of 15 cubic yards of trash
and vegetation from the creek. After several years in which trash
seemed to be declining, it rose again to about 10 cubic yards.
Most of it was food-related -- wrappers, cans, bottles, etc.
There were very few plastic bags, which attests to the success of the
ordinance banning them. We also removed a number of large items
like tires, shopping carts, bicycle frames, and a gate.
Photos of the 2016 creek cleanup are available here.
The 2017 cleanup will be May 13. Plan to join us!
Salmon need clean water to live and reproduce, not a creek full of trash
In August, volunteers propagated native grasses for our winter restoration project on Civic Park's Creekwalk.
