Update 2024-10-06: Clean Withlacoochee River, but some stretches flooding, and more rains coming 2024-10-04.

Valdosta’s Wednesday water quality samples show the Withlacoochee River clean after Hurricane Helene. Valdosta’s Wednesday a week ago samples corroborate clean before Helene, matching WWALS testing.

There are no new WWALS test results, because none of us have had electricity, which is needed to incubate the samples at 95 F for 24 hours. Two WWALS testers have power back, so maybe some new results soon.

The weather report is sunny for the next week, although you never know what might blow in off the Gulf or the Atlantic.

Many national, state, and local parks are closed, especially on rivers.

Upstream rainfall now running downstream is causing widespread river flooding. See separate report on the Alapaha River.

If you can, please stay home until the power and road situations are better.

Afterwards, there will be plenty of more opportunities for pleasant paddles and chainsaw cleanups.

Clean Withlacoochee River After Hurricane Helene 2024-10-02 Despite Upstream Spills: Tifton (huge), Sycamore (tiny), Valdosta (small).

No new sewage spills were reported in the past week in the Suwannee River Basin in Florida.

But three cities spilled in Georgia: Tifton (three huge spills), Sycamore (one tiny spill), and Valdosta (one small spill due to a tree falling on a lift station). See separate report.

With the hurricane rains, some contamination may have washed into the rivers. And there may have been sewage spills elsewhere not yet reported.

However, like after Hurricanes Idalia and Debby, it looks like the rain has diluted anything that did get into the rivers.

For context, see: https://wwals.net/issues/testing

The numbers in the chart boxes indicate E. coli levels as colony-forming units per 100 mililiters (cfu/100 mL), according to Georgia Adopt-A-Stream bacterial monitoring protocols:
Zero (0) is what we want to see, and often we do, on the Alapaha and upstream on the Suwannee Rivers.
From 1-125 is within long-term average limits according to U.S. EPA and Georgia and Florida state agencies.
From 126-409 long-term is not good, and is likely to make some people sick.
From 410-999 is likely to make some people sick; try not to get that water on you.
From 1,000 and up: high alert; best not to get close to that water without gloves; wash clothes afterward.

The letters before the numbers indicate the source of the datapoint, as in W100 means 100 cfu/100 mL found by a WWALS tester.
