State of Bay-Delta Science Book: Fact or Fiction?

by Dan Bacher
The CAL-FED "Science" Program has published a book, the "State of Bay-Delta Science, 2008," summarizing the "new knowledge" gleaned from eight years of CAL-FED science research into water supply and water quality, ecosystems and levee fragility in the California Delta. Unfortunately, the same agency that published the book has presided over unprecedented collapses of Central Valley chinook salmon and Delta fish populations in recent years.
State of Bay-Delta Science Book: Fact or Fiction?

by Dan Bacher

The CAL-FED "Science" Program yesterday published a book, the "State of Bay-Delta Science, 2008," supposedly summarizing the "significant new knowledge" gleaned from eight years of research into water supply and water quality, ecosystems and levee fragility in the California Delta, according to a CAL-FED news release. However, the question is whether the book is a non-fiction publication based on scientific fact - or actually a highly compromised work of science fiction.

For those not familiar with CAL-FED, it is the joint-state federal agency, formed after a "Water Summit" by the state and federal governments in Sacramento in 1994, that has presided over the dramatic decline of Central Valley chinook salmon, Delta smelt, longfin smelt, green sturgeon, white sturgeon, striped bass, threadfin shad and other fish in the California Delta-San Francisco Bay Estuary.

The collapse of these species has huge implications for fisheries up and down the West Coast, since the Sacramento-San Joaquin River Delta is the largest and most important estuary on the Pacific Coast. Recreational and commercial salmon fishing is closed in ocean waters off California and Oregon for the first time in history this year, due to the collapse of Central Valley fall run chinook salmon populations.

Those of us aware of the numerous examples of political manipulation of science to serve corporate agribusiness and water developers under the Schwarzenegger and Bush administrations have become very wary of "political science" masquerading as "natural science" in reports such as this one. For example, the Delta Vision Blue Ribbon Task Force, a supposedly "independent" body appointed by Arnold Schwarzenegger, released a report last week advocating the construction of a peripheral canal and more dams to "restore" Delta fisheries, even though they would certainly further imperil collapsing populations of Central Valley chinook salmon and Delta fish.

The CAL-FED publication was released on the eve of the 5th Biennial CALFED Science Conference, initiating the gathering of 1,200 San Francisco Bay/Sacramento-San Joaquin Delta scientists, managers and policy makers at the Sacramento Convention Center. The effort was led by Michael Healey, a former CALFED Lead Scientist and Science Advisor to the Governor’s Delta Vision Blue Ribbon Task Force.

“This is a landmark publication summarizing our current understanding of the Delta by the most knowledgeable experts on the estuary,” claimed Cliff Dahm, CALFED Lead Scientist. “I envision this as a go-to book for managers and policy makers, as well as interested members of the public that are working to gain a better understanding through science of forces at work in the Delta."

One of the key findings, in an apparent attempt by "political biologists" to exonerate the Bush and Schwarzenegger administrations from their role in engineering the Pelagic Organism Decline, as well as the collapse of Central Valley salmon populations, appears to dismiss water exports as a primary cause for the unprecedented fishery collapse.

"Since 2001, both public and scientific attention has focused on the unexpected decline of several open-water fishes (delta smelt, longfin smelt, juvenile striped bass, and threadfin shad)," the report claims. "It is clear that export pumping is only one of several factors contributing to the decline. Other factors include changes in food supply, loss of habitat and toxic chemicals. (Chapter 4).

Even worse is this statement in the same chapter, "Nevertheless, there is no conclusive evidence that export pumping has caused population declines. The lack of unequivocal evidence of pumping of large effects of pumping on fish populations does not rule out such effects, and for rare species such as Delta smelt, caution dictates that potential effects should not be ignored (p. 89).

The report admits on Page 87 that "Export pumping has been blamed in part for the declines of species such as striped bass (Stevens et. al 1985), Chinook salmon (Kjelson and Brandes 1989), and Delta smelt (Bennett 2005). However, the document then goes on to say "no quantitative estimates have been made of the population level consequences of the losses of fish caused by export pumping."

Now doesn't it make sense that if the CAL-FED scientists were going to do a truly scientific study of the reasons for fish collapses, they would engage in an all-out effort to develop "quantitative estimates" of the losses of fish destroyed by the operation of the massive state and federal pumps that export water to subsidized agribusiness and corporate water developers?

As Patrick Porgans, independent natural resources consultant so accurately points out, "if the scientists developed quantitative estimates of fish population losses that unequivocally demonstrated the huge impact of the pumps on imperiled fish populations, that would be the kiss of the death for the operation of the pumps. After all, this is not really about fish, but about the mega corporations that receive subsidized water from the state and federal projects only to sell the public back its own water."

The report fails to mention that some of the largest annual water export levels in history occurred in 2003 (6.3 million acre feet), 2004 (6.1 MAF), 2005 (6.5 MAF and 2006 (6.3 MAF). Exports averaged 4.6 MAF annually between 1990 and 1999 and increased to an average of 6 MAF between 2000 and 2007, a rise of almost 30 percent. The Pelagic Organism Decline and the year classes of Central Valley chinook salmon in collapse correspond directly to the years of record exports, but I couldn't find anywhere in the publication where this crucial bit of scientific data is mentioned.

Other "key findings"of the report include:

• The Delta of tomorrow will be very different than it is today. Intensifying forces of change, such as land subsidence, rising sea level, species invasions, earthquakes and regional population growth, virtually guarantee that current land and water use in the Delta cannot be sustained. (Chapter 1).

• Many toxic chemicals are a concern in the Delta. Organisms can often be affected by very low concentrations of contaminants. Effects can be magnified though concentration up the food chain or synergistic effects of mixtures. (Chapter 3)

• With climate change, California will become warmer, more precipitation will fall as rain and less as snow, the snowpack will be much reduced, and there will be less groundwater recharge. These changes will challenge the capacity of California’s water management system to provide reliable, high-quality water to satisfy human and environmental needs. (Chapter 6)

Other areas of the book deal with Delta history, science, geophysics, water quality and supply, aquatic ecosystems, levees, climate change, policy development and some themes that are crosscutting across areas and issues.

The conference where the book was unveiled features seminars on the Pelagic Organism Decline, salmon management and ecology, estuarine food webs, water quality, riparian habitat and a host of other topics. Again, the topic of export pumping is curiously absent from the conference sessions, as far as I can tell, with the exception of two sessions, one entitled "Evaluation of Daily Delta Flows and Delta Smelt Salvage Density Patterns" and "Splittail Population Dynamics and Water Export from the Delta."

Ironically, as the conference presentations are being made, our public trust fisheries continue to collapse. CAL-FED, a joint federal-state agency, has spent hundreds of dollars on scientific studies, conferences and "restoration" programs, but has been a dismal failure to date.

The reason for its failure is that the state and federal governments have constantly resisted taking the drastic measures needed to restore salmon and other fish populations, including dramatically reducing water exports from the California Delta and taking drainage impaired land on the west side of the San Joaquin Valley out of production. The CAL-FED Process to date has produced nothing but the collapse of Central Valley salmon fisheries and the Bay-Delta ecosystem.

The CAL-FED process has been an elitist process where the people most impacted by fishery declines - recreational anglers, commercial fishermen and California Indian Tribes - have been excluded from the decision making process. Meanwhile, those who have presided over the destruction of public trust fish populations - the Bureau of Reclamation and the California Department of Resources - have completely bent over to serve the needs of corporate agribusiness and the state water contractors.

Although I think there is some interesting information available at conferences like this and in the CAL-FED book, the problem is that there are lot of agency staff and consultants making good salaries incessantly "studying the issue," often with apparently pre-determined conclusions, while failing to stop the decline. The state and federal governments have set up a de-facto "restoration industry," in cooperation with some corporate funded NGO's, that extracts hundreds of millions of dollars from the taxpayers with fishery collapses the only concrete result!

Patrick Porgans often refers to CAL-FED as "CAL FED UP." This is an appropriate term to describe his and my view of the agency that has squandered hundreds of millions of dollars with only unprecedented fishery collapses, yearly conferences and questionable documents to show for all of the money spent while it refuses to study the quantitative impact of the operation of the pumps on fish populations.

by changing words in Delta vision draft
Changing words can change meanings to suit the needs of developers;

example;

"do not induce (inappropriate) new development to occur in floodplains, lands below sea level, or other locations at risk of flooding in the primary or secondary zones."

from draft section 6.3.3

the inserted word was "inappropriate", which is a matter of opinion open to interpretation. This could open the doorway for unsafe development on delta islands below sea level. Part of the plan to push the farmers off the islands and replace with tract homes behind unsafe levees??
by small farmers can coexist with nature
In the rush to invite developers to build behind new levees, the Delta task force should not forget that the process that created the islands was tule reeds decomposing and building up peat soil over time, and only a few decades of levees and loss of tule habitats resulted in the island's current position below sea level;


"Submerged islands

Twitchell and other delta islands are slowly sinking, their soil eaten away by wind, rain and farming. Most are more than 20 feet below the surrounding water. Only a system of increasingly pressured levees keeps them from being flooded.

A collapse of the levees would bring in saltwater from San Francisco Bay, damaging delta ecosystems and jeopardizing the state and federal programs that pump fresh water out of the delta for farms and cities to the south.

The Geological Survey project started 15 years ago as a small experiment on two, 30-foot-by-30-foot plots to see if growing mostly tules and cattails would help rebuild the islands' soil.

The plants can grow high enough to dwarf the average adult. As they die and decay, they slowly build up the peat. The soil under the 15-acre site has risen 1 to 2 feet since the project was moved there in 1996.

"All that soil out there are plants that grew 6,000 years ago and didn't decompose completely," said Robin Miller, a biogeochemist with the Geological Survey. "That's what peat is. So we're just making the same thing happen that happened here for millennia."

About 2 1/2 years ago, as they measured the plants' ability to restore the islands' soil, scientists noticed that their "big garden," as Miller calls it, was removing a lot of carbon dioxide, one of the greenhouse gases blamed for global warming.

"We were capturing a lot of (carbon dioxide) at levels much greater than other systems - marshes and forests, grasslands," said Roger Fujii, the project's director and the bay-delta program chief for the Geological Survey's California Water Science Center.

Scientists say the cattail and tule plot removes two to three times as much carbon dioxide as the other natural green spaces."

Can farmers give up some land on their perimeter to help raise the levels of the land by building up peat soil over a few years? Rising two feet of land since '96 is faster than expected, it wouldn't take so long to bring 15 feet below sea level to above sea level..

Tule reeds could also be harvested for making reed boat and rafts similar to the Patwin Wintun and Miwoks. Reviving lost indigenous cultures like tule raft weaving is not only helpful to descendents of Native American tribes it is also practical for modern peoples to interact wisely with nature as the indigenous have here for centuries..

Peripheral canal and "dual conveyance" ideas remain very abstract in the delta task force draft and seems to be poorly planned and should be protested locally as water theft by San Joaquin agribusiness corporations who are growing the wrong sorts of crops on their dry land. Introducing drought tolerant crops like high protein tepary bean that are indigenous to this dry region would be far more practical than attempting to irrigate temperate crops like lettuce in desert-like conditions of the San Joaquin valley..

There's an already existing tule reed boat building class happening in Marin;


"The Tule Reed Boat Project consisted of four Cultural Arts events culminating in the building and launching of our collaborative, handmade Tule Reed Boat using native arts, skills and natural materials.


1) Harvesting Tule Reeds in Susuin Bay Marsh

2) Native Arts and Skills training sessions for children and adults

3) Building an 18 foot Tule Reed Boat at Point Reyes National Seashore (PRNS)

4) Launching the Tule Reed Boat at Tomales Bay State Park.

Watershed Preservation Network, Point Reyes National Seashore, and Mother Lode Musical Theatre partnered for the project and invited the general public to attend and participate in all four events through an extensive outreach program. Two Marin schools (K-5) were chosen to assist in building the boat, although the day of the boat building saw over 400 school children participate!

The Tule boat is housed and peroidically on display at the PRNS, as well as accept potential invitations for display at the Discovery Museum, Marin Museum of the American Indian, the Drake's Pageant and the California Academy of Arts and Sciences.


The Tule Reed Boat Project is a unique collaborative process of rediscovery of Native American skills, arts and traditions and early California history and life-styles. Hands-on training and participation allows for participation by all ages, cultures and peoples. Our knowledge can be expanded as we help teach each other and learn together.

There was a significantly broad representation of various community groups participating: Inter-Tribal Council, Miwok Archaeological Preserve of Marin, Native American elders and storytellers, California Indian Storytelling Association, paleotechnologists, native skills artists, Drake Navigator's Guild, California History scholars, interpretive rangers from Tomales Bay State Park and Point Reyes National Seashore, Marin Schools, as well as the general public.


Expression of the arts and culture through building a Tule Reed Boat as a community project created a lasting legacy of enlightenment, knowledge and cooperative spirit, as well as a wonderful natural art piece – the Tule Boat. Every aspect of the project was interactive, and gave participating members of the public direct experience learning and creating with highly artistic native crafts. The art activities included the following: storytelling, textile arts, use of native plant materials, native skills and techniques, graphic arts, visual arts, photography, digital video, and drama, dance and music.

Over 800 children and adults particpated throughout the four month project in four separate events!"
