Bad Friday and Saturday water quality results, Withlacoochee River 2020-07-11

Update 2020-07-14: Bad Friday and Saturday water quality results, Withlacoochee River 2020-07-11.

Not looking good downstream on the Withlacoochee River. Madison Health unusually tested on a Friday, and found too-high E. coli results at Florida 6, just above Madison Blue Spring: 414 cfu/100 mL. Saturday, WWALS results at Knights Ferry Boat Ramp were horrible: 5,233. Nankin Boat Ramp results were merely too high: 600. State Line Boat Ramp was within acceptable limits Saturday, but that contamination probably washed down that far by Sunday and well into Florida by this morning.

Thanks to WWALS testers Michael and Jacob Bachrach for collecting those downstream Withlacoochee River samples, and to Suzy Hall for providing the results. See also What do these numbers mean?

Friday Conn got 2,100 on Crooked Creek at Devane Road. Remember, Crooked Creek runs into Okapilco Creek downstream of US 84. That 2,100 is actually lower than many results we’ve seen at that location, and Crooked Creek has much less flow than Okapilco Creek. So that number is not enough to account for the 5,233 downstream of Okapilco Creek on the Withlacoochee River at Knights Ferry Boat Ramp the next day. Did it come from somewhere else, such as upstream on Okapilco Creek?

This map may help with understanding where all these places are.

However many places the E. coli came from, there is reason to believe that the most likely sources are cattle.

Meanwhile on Saturday, upstream WWALS testers Conn Cole and John S. Quarterman found good results on the Little River at GA 76 (Cook County Boat Ramp) and GA 122 (Folsom Bridge Landing), as well as at GA 122 on the Withlacoochee River (Hagan Bridge Landing). Friday Conn Cole aso got good results on Okapilco Creek at US 84.

Plus, Valdosta’s Friday results for US 41, GA 133, and US 84 are all good. Valdosta did get a high Fecal coliform result for US 41, but we go by E. coli. Thanks to Valdosta PIO Ashlyn Johnson for getting these Valdosta Friday results published this morning.

Back downstream, you don’t even have to count the blue-with-bubbles colonies to see Continue reading

Clean Little and Withlacoochee Rivers to GA-FL line 2020-07-03

Update 2020-07-10: Data behind Florida bacterial advisory for Withlacoochee River 2020-07-09.

Update 2020-07-09: Possible bacterial contamination, Withlacoochee River, Hamilton, Madison Co. FL 2020-07-09.

Thanks to new WWALS testers Michael and Jacob Bachrach assisting Suzy Hall, results for samples taken Friday, July 3, 2020, are all green for Knights Ferry, Nankin, and State Line Boat Ramps on the Withlacoochee River. The samples I took upstream were also good: zero for Hagan Bridge Landing at GA 122 on the Withlacoochee River, and 333 for Folsom Bridge Landing at GA 122 on the Little River.

Suzy did remark, “The mosquitoes got a little annoying at Nankin!”

There was quite a bit of rain Friday, but almost all upstream on the Little River and upstream of Okapilco Creek at Moultrie (or Okapilco River, as Colquitt County calls it). While there was heavy rain at US 84 on the Withlacoochee River at the east side of Brooks County, meanwhile on the west side of Brooks at Dixie there was not much rain. So if we’re lucky, not much Continue reading
