Apparently the biggest slug of Valdosta sewage passed the state line on December 26, 2019.
Thanks to Chris Mericle for forwarding the December 25 and 26 data from the Suwannee River Water Management District (SRWMD), which I think is getting from from the Florida Department of Health (FDOH). I’ve combined those data in a table with the numbers from December 24, and ordered them from north (upstream) to south (downstream).
Here are the preliminary Valdosta Spill results for the FCOLI-MF and ECOLI-18QT samples we received on 12/26/18:

[2019-12-26:] The 10 mL and 50 mL FCOLI plates for the sample from Withlacoochee River @ CR 150 and the 50 mL FCOLI plate for the sample from Suwanee River @ US 90 had confluent negative growth. This amount of negative growth on a plate can outcompete the target bacteria so they were not used in the calculations to determine the final counts for these samples.

So it looks like the big lump Suzy Hall detected at 4,966 cfu/100 mL E. coli at Knights Ferry on Saturday, December 21st, the same day Sara Jay got 533 cfu/100 mL at the Little River Confluence that same Satruday. Suzy got even higher numbers, 6,767 cfu/100 mL, at Knights Ferry on Tuesday, December 24th, which is the same day FDOH saw counts start to rise at the state line.
Given the much lower counts I saw for December 27th, with Knights Ferry down to 300 cfu/100 mL, it looks like the main mass has passed the state line.
WWALS will continue to test. If FDOH keeps testing daily, we won’t need to in Florida, but we will in Georgia.
Meanwhile, Hamilton County, Florida, put up warning signs two weeks ago, like this one at Florida Campsites on the Withlacoochee River, and even upstream on the Suwannee from the Withlacoochee Confluence, at Suwannee River Campsites.
Valdosta still has not put any signs downstream of Sugar Creek on the Withlacoochee River. There’s still this one river caution sign at Troupville Boat Ramp, upstream on the Little River from its Confluence with the Withlacoochee River. just west of Valdosta.

Someone has decorated that signpost with flowers,
like the crosses you see at highway wreck sites.

Each bacterial test costs $6 for Petrifilms alone.
WWALS is spending about $40 a day on Petrifilms after this Valdosta spill.
