The revival of the San Joaquin River will officially begin with a shot of fresh water in October -- capping decades of courtroom battles and years of delicate negotiations over funding.

But the wrangling over the state's second-longest river is far from over.

Rio Mesa's 'litigation magnet'

Madera County plans in a vacuum, to the detriment of the entire region.
Sunday, Feb. 15, 2009 - Editorial in Fresno Bee


In the eyes of its developers and their supporters, the Rio Mesa area in southeast Madera County will one day be a sparkling new community of upscale homes and comfortable suburban living. In the eyes of its detractors, Rio Mesa is like watching an accident about to happen, and being too far away to help.

Dredge mining threatens salmon and other fish

An editorial appeared in the Fresno Bee today highlighting the dangers of dredge mining in California’s rivers and the environmental harm it causes along with harm to jobs and the economy.

Dredge mining in rivers does several harmful things: 1) It mixes up and returns potentially toxic material to the river flow. (Many rivers in California have mercury from gold mining in the 1800’s that have been embedded deeper into the sediment.) 2) The murky sediment returned to the rivers from the dredging makes swimming hazardous and unhealthy. 3) The disturbance of the river bottom also disturbs fish laying eggs. In particular salmon which lays eggs in the gravel bottom and young lamprey that can reside in gravel for up to seven years before maturing.

Extension sought for toxic discharge into the San Joaquin River

Map of Grasslands Bypass Project FeaturesThe San Luis and Delta-Mendota Water Authority along with the Bureau of Reclamation are seeking a 10 year extension to continue discharging 16,000 acre-feet of toxic water into the San Joaquin River. 

In November 1995, an interim project called the Grasslands Bypass Project was created to help prevent 50,000 acre-feet of toxic water from being discharged into the San Joaquin. For the past thirteen years the Grasslands Bypass Project has reduced the discharge of toxic water into the San Joaquin, but has not eliminated it.  Now, an extension is sought to continue the project for another 10 years even though it does not completely eliminate toxic water going into the San Joaquin River.

SACRAMENTO -- Three common pesticides are helping push the Pacific Coast's prized but imperiled salmon closer to extinction, a new federal report has found.

A 377-page draft study by federal fisheries experts contends there is "overwhelming evidence" that unfettered use of the pesticides is "likely to jeopardize the continued existence" of 28 salmon stocks off the West Coast.

Ammonia from Sacramento waste could hurt Delta ecosystem

After years of searching high and low for a culprit in the collapse of Delta fish populations, scientists are learning the problem may lie right under their noses.

The likely fish killer is ammonia, a common byproduct of human urine and feces.

Sacramento's regional sewage treatment plant is the largest single source of ammonia in the Delta. It discharges treated wastewater from nearly 1.4 million people into the Sacramento River near Freeport – without removing ammonia.
