Update 2020-07-30: Twomile Branch and Withlacoochee River 2020-07-28.
Valdosta reports very high fecal bacterial results for Friday at GA 133 on the Withlacoochee River: 1,410 cfu/100 mL E. coli and even higher for Fecal coliform. We don’t know what caused that: GA-EPD did not report any spills that day, and has not yet put up a new Sewage Spills Report for today. I am checking with the obvious suspects.
GA 133 on the Withlacoochee River west of Valdosta, east of Troupville Boat Ramp on the Little River.
On the Withlacoochee River, GA 133 is marked by the white circle, with the US 41 bridge at top right and the US 84 bridge towards the lower left, in this WWALS map of the Withlacoochee and Little River Water Trail (WLRWT).
Here is a chart of the data and recent rainfall. Note not much rain upstream on the Withlacoochee River. If the contamination came from upstream, it should have shown up first at US 41. Although conceivably it might have passed by US 41 on Thursday between samples.
One thing is for sure: whatever it was, it did not come from Brooks County.
Thanks to Valdosta PIO Ashlyn Johnson for posting this new data this morning.
