Basin Trend Reports

SD1 is undertaking a long-term effort to collect and compile data that describes the water-quality conditions of Northern Kentucky (NKY) streams. This information is compiled at a basin scale and a watershed scale to relate in-stream conditions to watershed characteristics. Study basins are used to group NKY watersheds into four logical reporting units – East, Central, North and West.

Information Use

NKY watersheds represent varying conditions with respect to the amount of development as well as sources of stream pollution.

As a result of the differences between these watersheds, SD1 initiated a comprehensive monitoring program to collect in-stream water quality, biology, physical habitat and stream stability data to establish current conditions and long-term datasets for trend analysis.

Reports

Data collection for trend analysis began in 2012 and is based on a 4-year basin rotation cycle. Current basin trend reports represent data collected from monitoring periods covering 2012 – 2015 and 2016 – 2019. Monitoring efforts are in progress for the period covering 2021 – 2024 and once completed, each basin trend report will be updated with additional data.
