Let’s say you owned a four-bedroom house, but one room was useless because of clutter. You’d probably eventually take a deep breath and clear out the crap. You’d reclaim the room. That’s pretty much the situation with many reservoirs in California. They’ve got too much gunk in them. And it’s crowding out space for water storage. But you don’t hear any deep breaths being taken in Sacramento. There’s no serious thought of removing the junk — silt, sand, gravel — and making more room for storm runoff.
