Most all of the PRK's water runs straight out into the ocean where it could be captured and used for irrigation, turf and other uses instead of using potable water for those purposes.

I don't mean to be rude, but show me the data.And also? Show me where to store MORE water. My brother had an idea to use GIANT rubber bladders in 50 to 100 feet of water. Water would stay cold and being out of the sun, would have little incentive for 'growth'....
And Please do NOT forget the (not a theory) aspect of Unintended Consequences. Channeling a rivers output into storage has already been shown to have generally ill effects. Just Look at the Colorado River which reaches the Sea Of Cortez maybe 2x per decade. Mexico is reallly angry and the space between where the river 'ends' in the USA and the former outlet is now Stinkin' Desert.
My 3/4 Wit brother in law is in favor of building a canal from IDAHO to use some of what he perceives to be surplus water. Good idea!
One last minor point. SanDiego water storage is in a couple dozen reservoirs. Some fairly small while the San Vicente is pretty good sized.....see picture.....Water stored now is about 45% of capacity......

I saw where some guy was cutting city curbs to allow rain water to flow back into the soil to prevent it running out into the ocean.
Cutting city curbs is illegal, but the results of the free irrigation reversed the laws and it started to become a thing. This increases ground water and also increases available evaporation for rain.
This is a variant of my idea by preventing it from entering the cement drainage systems in the first place.

Fact remains that I get only So Much rain in any given year. I checked 'the map' and see that my back yard, which now has a deep buried pipe (5' diameter or more?) runs along what was at one point a 'seasonal strream'. I've walked the pipe from end to end and it starts uphill at a big dip where the inlet is located. This is a drainage for several hundred vacant acres. Soil is of VERY low porosity, which I infer by the fact that after a day of LIGHT rain, water flows for the next week or more.
Following the pipe thru the neighbors yards, it goes UNDER a 4 lane street (was 2 when I moved here in about '87) , makes a 90 degree LEFT and pops out in the swamp on the South and West edge of the Guajome Park. I've explored ALL the trails and than some, finding a few water control half-dams and such to direct flow. The LOW SPOT of the lake, had a relieve of 50 feet or greater width Under Hwy 76 which flows out to the San Luis Rey River. I've walked the entire perimeter and that is THE low spot. The rest si a lot higher, forming a large depression At least 2 stand pipes, maybe 25 feet tall are to the north, but I can't imagine the water EVER getting that deep, especially since the underpass at the highway was finished.
There is a small UPPER lake which most people visiting the park never see. And no real way to get TO it except at one spot.
Attached image is of the park, showing one of my walks.....a elevation trace OF my walk is the inset.
People ARE ignorant. Wash Cars? Hose Driveways?

The water bladder idea is interesting at first blush until it gets punctured.
I saw where someone had a solar farm floating on water. I assume the water was to cool the panels to increase their efficiency and keep them from getting too hot, but water and electricity don't mix too well. If it was salt water, even worse and the salt corrosion would severely shorten the life of the solar panels.

ONE anchor drag and your bubble is burst.
When I pointed that out to my brother? We never did agree.
As for Solar on water? I get it. Sealing problems are epic. I can think of a couple solutions, at least one of which involves positive air pressure forcing the joins dry. You could also locate the solar 'farm' o shore and use a water to water intercooler to pump a more benign solution as panlel cooling.
Ocean water a couple hundred yards off shore is hardly ever over 65f which gives plenty of Temp Delta making panels more efficient.
Still too many people!

Just look at all of the massive cement lined drainage systems (that Hollywood routinely includes in their movies, Terminator, The Core, Grease, ...) through out the LA basin. It is dry all year long except for rainy season and runs straight out into the ocean.Same goes where I live. There is a cement lined artery system that runs through out neighborhoods and out to the ocean. If it had levies placed in it, the water could be kept and used for irrigation until empty. Easily 3 stories deep.
The local wildlife use the remaining pockets of water until the low spots are dried up so it would also extend the water supply for the wildlife.
The cement lined reservoirs are already there, they are just missing the stepped levies. No redirection of rivers necessary.

SoCal gets no more than a foot of rain per year. that's gonna be a big year.
a foot of rain is as much ass 10x that in SNOW.
Do the math and than multiply by some factor LESS than one.
Also? Don't forget that Rainwater from the streets of almost any large city is really a form of pollution. Oil? Gas? Tire dust? Animal / Pet waste? Industrial?
Treating the oceans as an Infinite Sewer is probably a bad idea.
I won't even hazard a guess as to the possibilities of treatment and storage.
TOO AMANY PEOPLE...
Too much is never enough
Wonder how much chum it generates.
