Drought Takes it Toll on Crops - While Rivers see Below Normal Flows
By mid July, Exceptional Drought (D4)
expands its grip further northward to encompass Kingman and Harper
Counties, according to the latest U.S. Drought Monitor. Exceptional
Drought is the highest intensity on the scale of the U.S. Drought
Monitor. Severe Drought (D3) progressed eastward to cover the western
half of the Counties of Sedgwick and Sumner with the eastern part of these
counties increasing a category to D2 of Severe Drought.
Below normal streamflow is seen across Central, South Central, and southeast Kansas. See the latest USGS map of daily streamflow compared to historical flows for July 14th below. (Refer to http://waterwatch.usgs.gov) Below normal streamflow conditions have been prevalant over Central and South Central KS since the end of April.
The United States Geological Survey (USGS) river gaging site on the Chikaskia River near Corbin is experiencing much below normal flows at this time of year. The river stage on the afternoon of July 15th at this gage site was reporting 1.72 ft with a discharge flow of 1.1 cfs (cubic feet per second). The COOP observer at Caldwell sent in the picture of the Chikaskia river...showing many sandbars appearing with minimal water in the streambed. Compare this picture with the one on the right when the river was at 2.42 ft.
