Our Mission: To protect and improve the health and environment of all Kansans. Outline and Streams: Reflections on 2019 that was...

• Provide a brief overview of the stream chemistry monitoring network and observed flows (and over the last decade).

• Provide a brief overview of select water quality parameters (sediment, phosphorus, and nitrogen), ranking their mean concentrations (1 lowest; 10 highest) over the last decade, partitioned by the 12 major river basins in Kansas.

• Highlight some of the observed impacts and benefits of the high flow events (2019).

The effects of flooding on aquatic and flood-plain ecosystems can have both negative and positive impacts. A negative impact (a significant fishkill) occurred (August 12, 2019) when fish became trapped in the receding floodplain waters along the (north of White Cloud, Doniphan Co).

Our Mission: To protect and improve the health and environment of all Kansans. Anecdotal Observations

Farmers were prevented or delayed in planting of their crops due to excessive rainfall and flooding (fall 2018); and, again in the spring through the summer months (2019).

Elevated stream flows persisted into October, November, and December (2019) suggesting there was considerable groundwater recharge (i.e., raising groundwater levels).
