Much of the torrential rain that fell on Southern California this week flowed right into the ocean, just like it did before the state's epic drought.

That seemed like a good idea for many years, as storm drains provided a crucial defense against flooding. But with California entering what may be a fifth year of drought, people are more likely to see a rapidly disappearing flood as a wasted opportunity

The State Water Resources Control Board approved a broad plan Wednesday for capturing more rain. The regulator is launching a road show this month to explain how it will dole out $200 million for projects to collect rain, part of a water bond voters approved in 2014.

Still, many believe more can be done, through projects large and small.
