Steelhead Restoration in Palo Alto
PALO ALTO -- The hard-luck steelhead trout of San Francisquito Creek will have one less obstacle to surmount once the storms of winter set the stage for their annual spawning runs.
A construction team has removed a century-old concrete barrier from a section of the creek in El Palo Alto Park on the Palo Alto-Menlo Park border, restoring the streambed to a more natural course. The roughly 40-foot-wide structure, known as a weir, had acted at times as a dam, trapping the federally threatened fish on either side.
Jared Blumenfeld, regional administrator for the U.S. Environmental Protection Agency, joined a throng of government officials and local conservationists Thursday for a celebration of the project's

completion. The $309,400 initiative is among 48 projects to receive more than $28 million in funding from the EPA since 2008 to protect and restore San Francisco Bay.
"Small things can make a really big difference," said Blumenfeld, noting the weir removal will enable steelhead to gain better access to many miles of habitat, particularly on the Los Trancos Creek and Bear Creek tributaries.
The barrier was built long ago to support a two-story retaining wall that prevents the southern bank of the creek from eroding. The wall bolsters two bridges that cross the creek, one for pedestrians and the other for Caltrain, and protects the root system of "El Palo Alto," the historic redwood from which the city of Palo Alto derived its name.
Crews under the leadership of the San Mateo County Resource Conservation District replaced the weir with rocks and boulders that will keep the retaining wall secure while allowing steelhead to move much farther into the San Francisquito Creek watershed, which empties from the Santa Cruz Mountains above Woodside and Portola Valley into the bay.
Central California Coast steelhead were once abundant in ocean and bay streams from Sonoma County to Santa Cruz, but their numbers plunged in the 20th century due to habitat degradation. San Francisquito is deemed an "anchor habitat" for the species, whose population in bayside streams has been decimated.
The segment of San Francisquito Creek at El Palo Alto Park is mostly dry now, but it swells once winter storms arrive. The weir had its greatest impact during low to moderate flows, blocking adult steelhead charging up the creek to spawn and trapping juvenile fish making their way down to the bay.
There is still more that can be done to help the steelhead here, said Jerry Hearn, a Portola Valley resident who has been working on restoring the San Francisquito watershed for two decades. The biggest obstacle remains Searsville Dam in Stanford University's Jasper Ridge Biological Preserve. The university, beset by an environmental lawsuit, is studying whether to remove or modify the dam.
Hearn, 68, said it is gratifying to see the weir torn away some decades after he and fellow conservationists first proposed it. Just a little boost, he said, can mean a lot to the dogged steelhead.
"The fish can get astoundingly far up those canyons," he said. "It's all about energy expenditure as you go upstream."

Here's why! In spite of all our efforts (fighting law suits, fighting against phoney science with regard to predation by striped bass, fighting reg change proposals that would further decimate our striped bass fishery) all our fisheries populations are sinking at a steady rate. The below release details the abject failure of those agencies with the responsibilities of maintaining public trust resources and why our fisheries are crashing.
Tuesday night, January 25, 2011, an historic event happened. A coalition of 30 environmental, environmental justice and fishing groups delivered to a state agency, The Delta Stewardship Council, a consensus document designed to begin to heal our S.F. Bay-Delta watershed and its fisheries, and also provide a pathway for California to have water system reliability.
The NCCFFF has been a driving force in this process for more than a year through helping to write a foundational report,California Water Solutions Now,reaching out to the Delta Stewardship Council, beginning a small group of individuals to plan a process for input to the council, and finally the arduous work of creating a consensus document for submission. These are recommendations on the Environmental Impact Report for the Delta Plan. Our document can be viewed at: http://www.ewccalifornia.org/reports/DeltaPlanScopingDocs.pdf
