Los Angeles has a system of cement washways that move large amounts of rainwater to the ocean to prevent flooding that used to happen semi-regularly.
If they stored that water in reservoirs, they wouldn’t need to get so much of their water from the various aqueduct systems used today.
Such a system could effectively buffer the negative impact of droughts, while still serving the purpose of flood prevention during wet years.

- Rebelgecko 8y agoWould that exacerbate the problem of nasty runoff from agriculture? A large part of why the Salton Sea is the cesspool that it is is due to salt and chemical runoff from farms in the area.

- jandrese 8y agoPossibly, but it seems like the setup to a bunch of news stories about heavy metals in our almonds.
- jedberg 8y agoThey could literally just dam up the spillways for the washways, let the washways fill up with water, and then pump the water out of them into treatment plants during summer. Make the washways deeper to handle more water. It would cost money, but a lot of the infrastructure is already there.
