But yeah, Water use in LA has to be a tough balance. I essentially spent 2002 in LA every 3 weeks -- so I guess I kinda "lived there". Mostly at hotel near the Airport I tried to explore when I could and noted the ditches and runoff areas.

But I started to get wrapped-up in the Politics, and everyday stuff that goes on there -- it's complicated -- lots of issues on the Ballot! (off-topic, but interesting to me).

I was really impressed by the desalinization plant that converts salt water into drinking water. Further, the intricate system that brings water to the city from the mountains is amazing on such a large scale. If you fly in from the right direction, you can follow the aqueducts from the air -- good stuff.

Ah yes, maybe some of those roads of water were Mulholland's originals :

I know the latest in Orange County is a system to convert waste-water into drinking water. I know that may repulse people, but the Science behind it makes sense and is completely safe. Recycling at its best!

Here in MO, we have the "Stream Team", which I belong, to test and clean-up local streams to evaluate runoff toxins -- which looks like what people at the link are attempting: to restore bodies of water (the LA River) to the natural state instead of a concrete basin. The water quality has to be terrible, but during the rainy moments, it must serve a purpose.

Not sure, what do you think about it? Seems to be necessary, but hazardous.

We need the LA River for flood control, but we need water like mad. Anything that we can do to recapture runoff is a winner to me. From my POV, just getting the quality up to gray-water status is enough to help. Here is the LA River revitalization plan from April 2007 :

This is the part I like in Chapter 4 :

Chapter 4 - Revitalize the River

(Page 3 of 22)
Goal: Enhance Flood Storage
Recommendation #4.1:
Identify opportunities for peak flood storage outside the channel to reduce flow velocities in the River to sub-critical (less than 12 feet per second) levels. This will support the maintenance and reestablishment of vegetation.
Recommendation #4.2:
Identify opportunities for selective acquisition of additional rights-of-way to expand the River’s floodplain.

...

Goal: Restore a Functional Riparian Ecosystem
Recommendation #4.13:
Create a continuous functional riparian corridor that provides habitat for birds, mammals, amphibians, reptiles, invertebrates, and fish within the channel bottom.
Recommendation #4.14:
Connect this corridor to other significant habitat and migration routes along the tributaries and into the mountains.
Recommendation #4.15:
Improve water quality and provide fish passages, ladders, and riffle pools that would support desirable fish species, including steelhead trout if feasible.
Recommendation #4.16:
Bio-engineer the River’s edge where feasible to create and restore wildlife habitat along the upper reaches of the River.

Ultimately, stored water could be used for irrigation or infiltration. Other downstream areas may offer selective benefits (for example, the Spreading Grounds, or Taylor Yard), but the associated land areas are much smaller, and consequently would accommodate less water unless basins were quite deep.

If you could restore the LA River, you could have a complement to the
