Caption: The Chart displays the frequency of turbidity readings <100 NTUs at the Eldridge Station on Sonoma Creek in 2001 and 2002. This dataset is taken from the larger set of all turbidity frequencies, where the majority of readings fell between 0 and 100 NTUs. The largest number of values fell in the 10 to 19.99 NTU bin (10,297 readings, or 1,716 hours, in that range). Turbidity readings >25 NTUs have been shown to impair salmonid feeding (Siegler et al. 1984). Data provided by the Sonoma Ecology Center. Click Info Links for more information.
