One fish, two fish, smelt fish, true sitch

California has enough rainfall to address local droughts, claims CPC's water policy director Edward Ring—but the State regularly and wastefully dumps water into SF Bay to try to save the Delta smelt fish. Why, decades after this program began, is the smelt fish population no better off—while Bay Areans are being forced into strict water rationing? From a 9.4 newsletter.
For the last several years, as summer turns to fall, state and federal regulators reduce the amount of water that gets pumped south in order to help the Delta smelt, an endangered fish. This year is no exception. In what is referred to as the “Fall X2 Action,” the pumps are about to be throttled down again. Water agencies at the receiving end claim the reduction, set to last about two months, will cost them up to 400,000 acre feet.
The reason the state wants to let this much water escape into the San Francisco Bay is to improve habitat for the endangered smelt, but critics of this strategy claim that smelt haven’t been found in the area, making the action fruitless. They also claim that regulators have the authority to restore higher rates of pumping without requiring a protracted bureaucratic process.
To learn more details, refer to an excellent recent report by Don Wright, “Fall X2 Line.” It not only explains the immediate situation, it provides background information for anyone unfamiliar with the agencies and regulations involved.
Meanwhile, this situation invites some strategic questions that ought to dominate water policy dialogue in California, but don’t.
1. Why does state water policy continue to assume more flow through the delta will cause endangered and threatened species to rebound, when despite 20 years of continually escalating restrictions on water withdrawals, they can point to almost no positive results?
2. When will the state recognize the role of introduced predators that feed on salmon and smelt, and either remove limits on fishing these predators, or abandon efforts to save the weaker native species?
3. How can the legislature justify the estimated $7 billion cost to impose strict water rationing on every urban resident in the state in order to save 400,000 acre feet per year, when simply allowing the delta pumps to operate normally in September and October would supply an equivalent amount?
4. Why is the state unwilling to invest in practical water supply infrastructure that could eliminate water scarcity forever?
To that last question, our capacity to harvest storm runoff during the winter and spring storms is only limited by our lack of appropriate infrastructure, along with an apparent penchant to invest billions in low yield schemes such as urban water rationing.
For example, during the first three months of 2024, an astonishing 10.3 million acre feet flowed through the delta and out to the ocean. In the first quarter of 2023, the total was 13.3 MAF, whereas in Q1 of 2022, a dry year, only 2.0 MAF made it through to the ocean. When are we going to build the capacity to take the so-called “big gulp”? Imagine if we had pulled an additional 2-3 MAF out of the delta during both of those very wet winters. …
To turn around a regulatory apparatus fixated on rationing, California’s water agencies and water consumers would have better luck if they would agree on and aggressively promote specific, practical policy options. Collectively investing in the fish friendly delta diversions concept is an example of potentially game-changing infrastructure. It would involve creating a channel in an existing delta island, lining the bottom, and burying perforated pipes underneath a bed of gravel to withdraw fresh water during storms. With no impact to either current or fish, a 200 acre site could yield 15,000 acre feet per day.
