This week’s On The Radio segment discusses Iowa’s 2016 Water Summary Update, released by the Iowa DNR in October.

Transcript: Iowa’s 2016 Water Year, which ended on September thirtieth, is the third wettest year on record in 144 years.

 This is the Iowa Environmental Focus.

 The Iowa Department of Natural Resources recently released its most recent Water Summary Update. The report provides an overview of the status of Iowa’s water resources and significant events that affect water supplies using four categories: precipitation, stream flow, shallow groundwater, and drought monitoring.

 The most recent update is a snapshot of the state’s water resources from August 31 through October 10. The update reveals that average statewide rainfall was 6.29 inches or 2.91 inches above average, making it the rainiest September since 1986.

 “The 2016 water year, which began in October 2015, and continued through September of this year, surprised Iowans with major unseasonal events including flooding on Thanksgiving last year, rainfall in January, and major flooding in September. While perhaps unexpected, these are consistent with early predictions from climate scientists that global warming will be characterized by increased variability of weather patterns. For Iowans, this implies that we have to be vigilant and prepare year round. Always stay tuned to the current weather conditions and forecasts.”

Streamflow was also found to be above average throughout the state. Following heavy rain events at the end of September in the Cedar and Wapsipinicon River basins, peak streamflow in several locations was found to be the second-highest in recorded history. These values were only topped by the historic 2008 flood.
