But shutting down the pumps has not resulted in anything close to a “remedy.” Your logic is fallacious and illogical: “something’s wrong with my car so I will disable the gas and water pumps.” Usually in law there has to be a reasonable and demonstrable nexus or connection between the mitigation and the cause. I do not yet see one in this case. As you point out the causes of the smelt decline are unknown. So why shut down pumps especially after there is no recovery of the smelt? And in science you must have a control group. What if all the prior efforts to clean the Delta water is deleteriously affecting the food chain of the smelt? What if cleaner water makes it more difficult for smelt to hide from natural predators? Iatrogenic causes have not been eliminated (i.e., the remedy is the cause).
