The state really has to invest in reservoirs so that all that precious gift does not go to the ocean.

It never rains in Southern California? (Original Post)

They're looking to get the water into the aquifers underground. Reservoirs tend to lose by evaporation.

The worst part is that all this rain promotes heavy vegetation which becomes a fodder for the summer and autumn fires..

Capitol Journal: California should stop thinking about more dams. The state is brimming with them

California is already dammed to the brim. Every river worth damming has been. And some that werent worth it were dammed anyway.
Some old proposed dam locations were found to be earthquake-risky. Quake faults tend to frustrate reservoir planning in this state.
The fact is, however, there are nearly 1,500 dams in California. At least 1,000 are major, and 55 can hold 100,000 acre-feet or more of water. There are 36 reservoirs that can contain at least 200,000 acre-feet. Eleven are in the 1-million-plus category.
(snip)
Weve about used all the good dam sites.
And dams have become almost unaffordable.
Moreover, one dirty secret about dams a very major flaw is that they tend to silt up, gradually reducing a reservoirs capacity.
A 2009 UC Berkeley report estimated that about 1.8 million acre-feet of storage space had been lost to silt. It found that nearly 190 reservoirs had lost more than 50% of their original capacity.
(snip)
Former state Sen. Fran Pavley (D-Agoura Hills) told me two years ago that she tried several times to pass legislation appropriating money for silt cleanup. She also sponsored a bill requiring a state study. But the measures were killed.
I knew full well taking out silt would be quicker and less expensive than building a new storage reservoir, she said. But the priority was to build more dams.

(3,508 posts)4. 5 Ways California is Storing Water from Winter Storms
California is prioritizing groundwater recharge, stormwater capture, reservoir storage, water conveyance improvements and ambitious targets to build water resilience
State has committed more than $8.6 billion to build water resilience in the last two budgets and the 2023-24 budget proposal includes an additional $202 million for flood protection
SACRAMENTO California is taking urgent action to protect communities from climate-driven extremes in weather and expand the states capacity to capture storm runoff in wet years.
5 Ways California is Storing Water from Winter Storms
California isnt waiting to act were moving aggressively to modernize how we capture and store water to future-proof our state against more extreme cycles of wet and dry, said Governor Gavin Newsom. Were expediting projects across the state to maximize stormwater capture and storage above and below ground during times like these, reshaping our water systems for the 21st century and beyond.
Leveraging the more than $8.6 billion committed by Governor Newsom and the Legislature in the last two budget cycles to build water resilience, the state is taking aggressive action to prepare for the impacts of climate-driven extremes in weather on the states water supplies:
Advancing clear, ambitious targets to build drought and flood resilience, including increasing annual groundwater recharge capacity by 500,000 acre-feet
Fast-tracking groundwater recharge efforts by streamlining permits
Maximizing stormwater capture through new projects
Supporting reservoir repair and expansion to boost water storage above and below ground
Modernizing water conveyance Infrastructure across the state, including the Delta Conveyance Project
This budget funding includes $500 million that will be provided in 2025-26 to help ensure strategic water storage projects can be completed. In the 2023-24 state budget, Governor Newsom is proposing an additional $202 million for flood protection and $125 million for drought related actions.
FACT SHEET:
6 Ways California is Harnessing Winter
Storms to Boost Water Supplies
● California is boosting water supplies through groundwater recharge,
stormwater capture, reservoir storage, water conveyance
improvements and ambitious targets to build water resilience
● California has committed $8.6 billion to build water resilience in the
last two state budgets, and the 2023-24 budget proposal includes an
additional $202 million for flood protection
To help California cope with more extreme droughts and floods driven by climate
change, Governor Newsom and the Legislature have committed more than $8.6
billion in the last two budget cycles to build water resilience across the state and
protect communities on the front lines of extreme weather.
This budget funding includes $500 million that will be provided in 2025-26 to help
ensure strategic water storage projects can be completed.
In the 2023-24 state budget, Governor Newsom is proposing an additional $202
million for flood protection and $125 million for drought related actions.
The state is advancing targeted investments and aggressive action:
● Governor Newsoms Executive Order to capture and conserve more water
● Advance ambitious targets to build water resilience across the state
● Fast-track groundwater recharge projects
● Maximize stormwater capture
● Expand storage above and below ground
● Modernize conveyance infrastructure to capture more storm runoff

I love our state.
