Description: Abstract - In-stream water quality regulations of California state that silvicultural disturbances must not increase turbidity levels more than 20 percent above naturally occurring background levels. These regulations fail to take into account the natural variation of turbidity and suspended sediment concentration along a short stretch of an undisturbed stream. At Janes Creek and Miller Creek in northwestern California, natural variations in turbidity and suspended sediment concentration along stream reaches of 292.6 and 110.6 meters were -.015 to 3.73 times that of the 20 percent man-induced increase tolerated by law.
