2009 California Central Valley Salmon Runs at All Time Low

The Pacific Fisheries Management Council has just released numbers showing California’s once abundant Central Valley salmon runs came in at a new all time record low in 2009.  The Council reports “In 2009, a total of 39,530 natural and hatchery Sacramento River Fall Chinook adults were estimated to have returned to the Sacramento River basin for spawning….The 2009 adult escapement estimate is the lowest on record and continues the declining trend in SRFC escapement despite the 2008 and 2009 closures of nearly all ocean Chinook fisheries south of Cape Falcon…”  The prior record low, set in 2008, was about 66,000. Fisheries managers believe that a minimum escapement of about 122,000 are necessary to maintain healthy stocks.

The Council’s report shows that federally protected runs of winter and spring run chinook both came in at less than 5,000 individuals each.  The San Joaquin River is in particularly bad shape with just under 2100 salmon, representing perhaps the last of their race there.

The last three years of salmon returns have each set new record lows and coincide directly with three of the highest years of San Francisco Bay Delta water diversions.  Delta pumping kills juvenile salmon migrating through the Delta to the sea.  It takes three years for surviving juvenile salmon to return as adults and to for fisheries managers to realize the full destruction caused by the pumps. 

“We’re watching our salmon disappear in exact concert with a 16 percent increase of Delta water diversions over the last decade,” said Dick Pool of Water4Fish. “The full throttle pumping of Delta waters is wiping out valuable salmon worth over a billion dollars to the commercial and sport fishing sectors.”

All salmon runs, and many other fish species in the Delta, collapsed in 2007 after a dramatic increase in pumping of water to points south. As a result, regulators closed all ocean fishing of chinook (also known as king) salmon in California and most of Oregon in 2008 and 2009 to save the salmon. The Central Valley stocks typically provide 90 percent of all king salmon harvest off California and about 60 percent of all king salmon harvested off Oregon in both sport and commercial fisheries.  When some ocean salmon stocks are that low, even healthy stocks that intermingle with damaged stocks as sea are put off limits to prevent accidental capture of too many of the interrmingling weak stocks, a process called “weak stock management.”

The economic analysis firm Southwick Associates has estimated that these closures have cost an estimated 23,000 jobs and $1.4 billion to the California economy. California has over 2,000 small and medium sized businesses that derive most or all of their income from the recreational and commercial salmon industry. These businesses include 1,200 commercial boats, 11 manufacturers, seven wholesalers, 904 retailers, 230 guides and charter boats, 74 marinas and hundreds of boat dealers and marine parts and service centers. 

Behind those statistics lies enormous suffering by families along nearly one thousand miles of Pacific Coast.  For two years boats have been tied up on docks, marina businesses have closed, and fishermen’s homes have been lost to foreclosure.    West Coast restaurants that once featured locally caught salmon are increasingly turning to imported fish as local harvests decline.

Agricultural employment in the seven county areas impacted by the pumping restrictions was actually up between 2008 and 2009, and the California almond industry had record shipments of 1.39 billion pounds in 2008-2009, up 10 percent over 2007-2008.  Over the same period, the Oregon and California salmon industries experienced near total shutdown.  

On average, San Joaquin Valley agricultural contractors got 80 percent of their contract allocations last year, although there were some localized shortages primarily due to drought. In comparison, the average Westside deliveries in the past two decades have been about 60 percent of full allocations. A key issue has been the reckless 16 percent increase in Delta pumping over the last decade above levels of the 1990’s.
