Klamath River Emergency Dilution Flows Not Required in 2017 From the Bureau of Reclamation: The Bureau of Reclamation announces that Klamath River emergency dilution flows will not be required in 2017 to mitigate the effects of a parasite called Ceratanova shasta (or C. shasta) on outmigrating juvenile salmon.
The winter-spring flows were conducted on multiple occasions during February and March 2017, after which Reclamation shifted its focus to planning for implementation of emergency dilution flows, which the court ordered to be implemented between April 1 and June 15 if certain disease thresholds were exceeded.
Specifically, the court ordered Reclamation to utilize up to 50 thousand acre feet to implement emergency dilution flows if: C. Shasta spore concentrations exceed 5 spores/liter (non-specific genotype) based on quantitative polymerase chain reaction at any sampling station, or Prevalence of infection of all captured juvenile Chinook salmon exceeds 20 percent for the preceding week at the Kinsman Rotary Screw Trap site.
These flows would be required until June 15 or until 80 percent of juvenile salmon had outmigrated if either of the preceding two thresholds were exceeded.
Clear Lake is also home to the Clear Lake Hitch, a federally-endangered fish, and holds environmental significance for the surrounding region’s plant and animal life.
“This Committee and the maintenance of a healthy Clear Lake will be a community effort,” said Assemblymember Aguiar-Curry.
Aguiar-Curry represents the 4th Assembly District, which includes all of Lake and Napa Counties, parts of Colusa County, all of Yolo County except West Sacramento, Dixon in Solano County and Rohnert Park in Sonoma County.
