Senate Committee Passes Bill to Put Moratorium on Suction Dredging
Yubanet – 4/28/09
By the Sierra Fund
Suction dredging disturbs fish habitat, putting endangered species such as Coho salmon and green sturgeon at risk. In addition, repeated government studies have shown that suction dredge activities disturb and mobilize the mercury left behind from gold mine operations.
Gold miners in the 19th century used an estimated 26 million pounds of mercury to extract gold from ore in California, with an estimated 13 million pounds lost to the waters and soils of the Sierra Nevada and Trinity Mountains. Suction dredgers often encounter mercury and gold-mercury amalgam, which tend to fall into the cracks of the riverbed like gold. Dredgers collect the mercury and amalgam, and treat it to release any gold that may have amalgamated with the mercury. They then recover the mercury and usually store it, though some miners dispose of it in an unauthorized manner, such as pouring it back into the river, onto the ground, or in to municipal sewer systems.
Suction dredges re-suspend and "flour" mercury, increasing the surface area and making it more readily available for bacteria to methylate. Methylmercury has been a regulatory concern of the State for years due its known serious effect on human health.
"The rules that govern this practice are woefully outdated," noted Martin. California Department of Fish and Game (DFG) was ordered by the
The Sierra Fund has worked with the state's leading scientists as part of our Initiative to assess and address the impact of gold mining on our state. Our report, Mining's Toxic Legacy includes research developed by the US Geological Survey as well as SWRCB on the impacts of suction dredging.

Sacramento to get stimulus funds for flood-control

The largest share of the new funding, $14 million, will help pay for flood-safety improvements at 96 locations in the area, including slurry wall sections on the American River, a closure structure at Mayhew Drain, and modification of the
Another $4 million will go toward 3,000 feet of levee improvements on the South Sacramento streams project, while $3 million funds restoration of 55 acres of oak and riparian habitat along the
The funding comes via the U.S. Army Corps of Engineers from the American Recovery and Reinvestment Act. It is in addition to about $180 million previously announced for the
"These federal funds are addressing vital needs within our community, from rebuilding schools, to helping the homeless, to addressing public safety issues," Rep. Doris Matsui, D-Sacramento, said in a statement. #

Sacramento contractor wins bid for Folsom Dam flood-control work
Sacramento Bee – 4/28/09
By Matt Weiser
The project is a joint effort between Reclamation and the U.S. Army Corps of Engineers. It involves building a new 3,000-foot-long concrete spillway adjacent to the existing main dam so that
Expected to be completed by 2015 at a cost of $1.5 billion, it is
The contract with Martin Brothers Construction is the second in a series of major construction phases for the project. It includes additional spillway excavation, construction of a stilling basin coffer dam, relocation of a 42-inch water supply pipeline, and access roads. The work will be completed in fall 2010, to be followed by additional building phases.

Steelhead cut free in salmon program completion

Second-graders Jessica Christie and Tamia Crackel knelt on a rock on the edge of the
”Where'd it go?” Christie asked.
”It went right under that big rock,” answered Jeff Self, a volunteer for the resurrected Salmon in the Classroom program.
Pair after pair of students in Jake Habib's Dow's

The program aims to teach children about salmon and the environment they live in. As Self quizzed the class about the parts of a watershed, the students shouted out correct answers in unison, sometimes before Self finished the question.
Habib said the students checked on the steelhead every day, taking the temperature of the water, predicting when individual fish would hatch, keeping journals and playing games.
”The fish are huge this year,” Habib said, “just huge this year.”
Americorps members visited to do other salmon-based activities.
Self said that teachers are already inquiring about the program for the coming school year.
”Every time I go into a school it's like Christmas -- everyone is just super supportive,” Self said. #
