Notes:
a. 1986 sampling results were taken from the 1987 Lake Cochichewiclz Watershed Plan.
b. ND means no data was available or collected.
C. For results reported as below the detection limit(i.e., <0.01),the mean was calculated by using the median of zero and the maximum potential value,which in this case is
the phosphorus limit of detection(0.01).
