Update 2021-01-29: Very bad, health advisory, Withlacoochee River 2021-01-28.

As expected, the big rains Friday caused contamination on the Withlacoochee River, according to Valdosta’s upstream data for US 41, GA 133, and US 84. Everything was clean the day before, both upstream and down. We don’t know about downstream again until I tested Sunday. While Knights Ferry, Nankin, and State Line Boat Ramps were not as clean as we like, they were well within the one-time test limit of 410 cfu/100 mL E. coli. So it appears that if the downstream sites were contaminated Friday, most of that had already washed away in the rest of the rainwater by Sunday.
