You are now in California and the U.S. category.

Flowing over 250 miles to from the high desert of southern Oregon through the Cascades Mountains before emptying out into the Pacific Ocean in northern California, the Klamath River and its Coho and Chinook salmon and steelhead runs were vital to Native American tribes for thousands of years before settlers arrived.

But within decades of their arrival there would be half a dozen dams constructed on the river, effectively blocking salmon and steelhead migrations on what was once the third-highest salmon producing river on the West Coast.

California faces major changes in its water supply. The sooner everyone realizes these changes are coming, the better the state will be able to cope with what lies ahead.

Today’s changes are driven by efforts to end groundwater depletion, by sea level rise and loss of snowpack, salts and nitrate accumulating in groundwater, new invasive species, population growth and California’s globalized economy and agriculture.

As promised a year ago, the state is at work restoring wildlife habitat in the Sacramento-San Joaquin Delta and Suisun Marsh, with six projects targeted for groundbreaking in 2016.

Through the Natural Resources Agency’s California EcoRestore program, state, federal and local interests are restoring tidal wetlands, blocking salmon from straying into dead-end irrigation channels and reconnecting rivers to their floodplains.

Environmental groups sued the Environmental Protection Agency on Wednesday to force new regulations on the disposal of waste generated by hydraulic fracturing.

The injection of hundreds of millions of gallons of wastewater from fracking into underground wells has been linked to numerous earthquakes in Kansas and several other states.

The suit calls for the EPA to update waste disposal rules that are decades old and precede the recent oil and gas boom made possible by fracking and horizontal drilling techniques.

Eldred Township is not the only place where people are protesting a proposed Nestlé bottled water extraction project. If approved, the beverage company would withdrawal some of 200,000 gallons of water per day at the site in Monroe County.

More than 280,000 members of the California-based Courage Campaign Institute, The Story of Stuff Project, Food and Water Watch, Care2, CREDO, SumOfUs and the Daily Kos have submitted comments to the U.S. Forest Service requesting the Forest Service not approve Nestlé’s new permit for water bottling in the San Bernardino National Forest, a press release from the groups said.
