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

One of the easiest decisions for California voters on the June 5 ballot should be Proposition 68. Vote yes on the $4.1 billion bond plan to fund parks and water projects throughout the state. The ballot measure is the first statewide parks and water bond to appear before voters since 2006, when the $5.4 billion Proposition 84 was approved by 54 percent of voters. Prop 68 would authorize $2.83 billion for parks projects that would fund everything from building Bay Area hiking trails to upgrading California’s 110 state parks.

One of California’s foremost experts on freshwater fish believes there may be hope for restoring native salmon to abundance – but there’s a catch: California must build the controversial Delta tunnels, he says. “The expected costs are tremendous and there is a lot of concern over that, but our paper is about what’s good for fish,” said Peter Moyle, a professor of fisheries with the University of California, Davis Center for Watershed Sciences. “Will the Delta tunnels be good for fish or not? I think they will.”

Most Americans are familiar by now with the concept of recycled wastewater. We all may not be completely comfortable with the concept of reusing treated sewage, but most of us have at least heard about it, and in some communities we know that it helps parks and street landscaping thrive. A handful of communities practice what is known as indirect potable reuse, which means using highly refined treated wastewater to recharge groundwater or a reservoir. This water is processed again in a conventional drinking water treatment plant before being delivered to customers.
