Report: State's big rivers in big trouble
By Garance Burke
California's two longest rivers, the Sacramento and the San Joaquin, were named the nation's most endangered waterways by an environmental group that considers them threatened by outdated water management and poor flood planning.
American Rivers, a conservation group that compiles the annual list, chose the Sacramento-San Joaquin river system because its collapse could threaten the water supply of 25 million Californians, flood the state's capital and damage the delicate freshwater delta where the two rivers twine.
"The Sacramento-San Joaquin Delta is on the verge of losing important fish species, and the communities that surround it already don't have adequate protection from their levees," said Steve Rothert,
State water officials did not immediately comment on the new report.

It will be a news flash mainly for the other 49 states.
Many Californians are already well aware of the myriad problems in the Sacramento-San Joaquin Delta and its two main rivers. They've lived for several years with water shortages caused by the Delta's environmental problems, and with the threat of its declining fish populations, aging levees and problem plumbing.
Yet making the No. 1 slot on the group's 2009 list of the 10 most endangered rivers is a dubious distinction that both environmentalists and water users say will bring renewed urgency to finally solve these problems.
"It can't hurt," said Tim Quinn, executive director of the Association of California Water Agencies. "We keep telling the world this system is in crisis. It's in crisis for the fish and the water supply. So the more attention we can get ... the better off we're going to be."
American Rivers, based in
The Sacramento-San Joaquin Delta certainly satisfies both categories. A massive habitat conservation effort, called the Bay-Delta Conservation Plan, is expected by the end of this year and aims to both restore imperiled fish populations and improve water delivery.
More than 23 million Californians and 3 million acres of farmland depend on Delta water.
A key proposal in that plan is a controversial canal. Up to 50 miles long and 1,000 feet wide, it would divert a portion of the Sacramento River's flow around the Delta to directly serve water diversion pumps near

Environmental and water-supply problems have created urgency at the state level to reverse the Delta's decline. Federal interest, however, has waxed and waned.
Nine fish species are in steep decline in the Delta, the largest estuary on the West Coast of the
Once the largest salmon run on the West Coast, a crash in the fall-run last year is likely to require a ban on commercial salmon fishing for the second year in a row. Federal officials cite ocean conditions as the main culprit, but problems in the Delta also play a role.
This includes water pollution from farms and cities, predation by foreign species and water diversions. Massive state and federal pumps near
There are also imminent threats to people.
The Delta is a 1,100-mile maze of waterways formed by weak levees first carved out of the estuary shortly after the Gold Rush. The levees form 70 islands that host a rich farm economy and several historic towns.
Those levees don't meet modern engineering standards and are under constant attack from storms and tides. Recent studies estimate there is a 62 percent chance many will collapse in an earthquake in the next 30 years.
A flood that size would draw a surge of seawater into the Delta from
Phil Isenberg, a former
Isenberg was chairman of the governor-appointed Delta Vision Task Force, which last year wrapped up two years of study to produce a set of comprehensive recommendations to heal the Delta. Those proposals are now being debated both by state lawmakers and the Bay-Delta Conservation Plan.
Basic water scarcity and the need to improve governance of the Delta, Isenberg said, are key issues largely overlooked by American Rivers – and by policymakers.
"You have to face up to the question of whether we have not reached the limits of how much water can be exported from the Delta," he said. "Having us described as the most endangered puts a lot of additional focus on the debate, and I think that is immensely healthy. But behind all the recognition comes the tough political questions."
Rothert acknowledged the Delta presents a thornier set of problems than most waterways his group has highlighted over the past 23 years. Yet he believes the attention can help.
As examples, the group points to San Mateo Creek in Southern California, where a proposed freeway extension threatened
"We don't have a choice but to develop a workable solution," Rothert said of the
