After I wrote the Sunday story about the water pumps at the Sacramento-San Joaquin River Delta, federal leaders tweaked their analysis of the delta smelt problem this winter.
The picture is still not good for this protected species, but it’s not quite as bad as it looked in early February. It might help keep the pumps running to provide water for farm and city customers later this year.
The federal analysis released last week says smelt deaths at the pumps are actually only 64% of the total allowed for the year, not 76% as had been reported.
Two numbers had been adjusted since I first reported on the smelt. The number of fish allowed to die at the pumps was increased from 305 to 362. And the number of fish reported to have died at the pumps is now 230, not 232.
