Coalition response...While this study acknowledges other factors that impact the fish populations, it continues to lay the primary blame on pumping operations in the Delta that send water to 25 million Californians and to farms that produce a healthy and safe food supply. It ignores reports that indicate that losses for salmon from predators are greater than those numbers salvaged at the Delta pumps. Salmon populations are well-documented to cycle up and down and have gone through three of these cycles since 1983. Interestingly, a four-year average of exports volumes leading up to high population versus low population shows that export volumes really don't matter. Exports were almost exactly the same over the years that population peaked as they were when populations were low ---4.85 maf for the high populations and 4.92 maf for the lows, or one and a half percent difference. Clearly, something else is affecting salmon beyond exports.
No one is denying that the numbers are startling to the casual observer. However, the study authors ignore the fact that Environmental Protection Agency officials denied endangered status to splittail, one of the fish species touted in the study, because of its high population. EPA biologists repeated their findings when discounting the high numbers salvaged at the pumps in 2011. In summary, the authors use numbers they select to support their position that the pumping of water from the Delta should be curtailed. This reasoning does not help to resolve the water issues we face today in California.
