*Data acquired over a 15-yr period (1994-2009; data missing in 2003) was used to determine annual 95% upper confidence limits (UCL) and 95% lower confidence limits (LCL) of the mean for each variable/reach/episode/stratum. Estimates of the 95% upper and lower confidence limit for the year of interest (e.g., 2010; a year outside the 15-yr period), along with the median, were compared to the 15-yr annual extremes to determine unusual conditions. Estimates where the median was higher than the highest annual 15-yr UCL or lower than the lowest annual 15-yr LCL were "low" or "high," respectively. Estimates where the LCL was higher than the highest annual 15-yr UCL or the UCL was lower than the lowest annual 15-yr LCL were "very low" or "very high", respectively.
