Streams_TrendLikelihood_Results

Trend analysis results for water quality data collected through King County's ambient stream water quality monitoring program. Trends were calculated for all sites with at least 5 years of data. Trend results are based on Mann-Kendall–style pairwise slope estimation with censored-data imputation using a truncated log-normal distribution. Trend likelihoods reflect statistical probability rather than regulatory exceedance or causal inference. Results may be sensitive to data gaps, sampling frequency, and changes in analytical methods over time.
