California begins study of canal's effect on delta

The study is designed to see whether a "peripheral canal," an engineered waterway that would go around the most environmentally sensitive area of the delta, is a viable solution to some of the delta's troubles.

Back in 1982, there was an epic political fight over the question of a similar canal that was eventually rejected by California voters. The study is supposed to take 30 months, which seems like a long time for a region in crisis.
