Creek Restoration Project Continues in Civic Park April 8

For our Saturday, April 8 workday, we'll care for our new
plants and start clearing next year's restoration area. No experience is required -- just a desire to make the creek a better place 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.

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.

    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.

    Other Recent Activities

    Sandbagging:  As 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).

    Arundo Removal:  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.
