On the Valley’s west side near Los Banos, something strange is happening this summer in the San Joaquin River — water.

The river has continued to flow to the Pacific Ocean throughout the first summer after an ambitious restoration effort began, sending a powerful signal about the project’s potential for success.

This end of the river has been dry in summer since Friant Dam was finished in the late 1940s.

By the end of 2012, officials are supposed to re-establish salmon runs, which perished after the dam was built. But officials need to learn a lot more about the river, 60 miles of which has not been wet year-round in decades.

Decision may have water implications for Stockton

Alex Breitler, Stockton Record

A federal appeals court ruled Friday that Central Valley steelhead were properly listed as a threatened species despite the fact they interbreed with rainbow trout, a decision that sides with fish agencies and environmentalists.

The ruling may have water supply implications for Stockton, said Kevin Kauffman, general manager of the Stockton East Water District.

Stockton East joined five other districts – South San Joaquin, Merced, Modesto, Oakdale and Turlock – in challenging the steelhead listing by the National Marine Fisheries Service.

Interested in learning more about what animals live in our watershed?

FLCR’s brand new “Common Animals of the Calaveras River” guides are now available to the public, free of charge!

Take this guide along with you on your boating trips, hikes, or simply in the dash of your car to identify birds, fish, a mammals that live in our watershed.. some of the animals you’ll see on the guide might surprise you!

Guides will be passed out to particpants at FLCR ‘s Monthly Riverwalk events, cleanups, and other activities.

These guides were made possible by a generous grant from the Resource Legacy Fund Foundation.

Every 2 years, the CA Water Resources Control Board revisits a “working list” of polluted rivers to help establish what is polluting our waterways and why.

Needless to say, the Calaveras River was included in the ever expanding list of polluted waterways in thier 2010 report.

They investigated the river all the way from New Hogan through Stockton, and developed a list of pollutants that will be included on the EPA’s “303(d) list”, which means that water quality standards have been exceeded and the indicated pollutant contributes to or causes the problem.

Here’s a basic list of pollutants they found in the Calaveras River from New Hogan all the way to Stockton  that are exceeding standards (Note: The lion’s share of the pollutants were found in the Stockton Diverting Canal to the San Joaquin River, and in parts of  the easter portion of the Delta waterways):

  • Organic Enrichment/ low dissolved oxygen (urban runoff/ storm sewers)
  • Diazinon (agriculture)
  • Mercury (resource extraction)
  • Chlorpyrifos (agriculture)
  • Pathogens (urban runoff/ storm sewers)

The City of Lathrop had to beef-up some of their levees to meet ACOE’s 200 year standards. So what do they do? They take those massive super-levees and put houses on top of them overlooking the SJ river. Anybody want some lemonade? – Jeremy

River Islands creating rare river view home sites

LATHROP – The only way historically to have a home in the Central Valley with a sweeping view of either the San Joaquin River or Sacramento River is to have a home elevated and hugging a levee.

That is about to change.

River Islands at Lathrop will have 900 of their 10,800 home sites atop the 300-foot wide super levee that is designed to protect against 200-year floods. They will have an unparalleled view of the San Joaquin River and distant vistas such as Mt. Diablo.
