All too high: One Mile Branch, Hightower Creek, and the Withlacoochee River, upstream and down.

The worst result in Valdosta Utilities’ Friday water quality results was at North Valdosta Road (US 41), upstream from most of Valdosta.

All were above the 1,000 cfu/100 mL alert limit.

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

There’s a 30% chance of rain today, then mostly sunny Monday and Tuesday.

Friday I said I wasn’t doing daily water quality reports after good Thursday results, but we’d best not ignore these

This is a prime example of why frequent water quality testing, especially by the City of Valdosta, is very useful. Nobody would have known about this contamination without these tests.

I’d avoid the Withlacoochee River for a few days at least, for paddling, fishing, swimming, or boating. Try the Alapaha or the Suwannee River upstream from the Withlacoochee, or farther downstream, or the Santa Fe or Ichetucknee.

Thanks to Valdosta Utilities for posting their test results on their website, even on a holiday Saturday. So far as I know, Valdosta is the only wastewater permit holder in Georgia that puts its water quality results on its own web pages.

The Florida agencies stopped water quality testing for the Withlacoochee River after they got several consecutive good results. After these Friday Valdosta results, maybe Florida wants to think again.

While the river gauges do not really show it, CoCoRaHS volunteer precipitation reporting shows Valdosta for Friday once again getting heavy rain that did not fall elsewhere.

Here is the WWALS composite spreadsheet with all these results, plus rainfall from river gauges:

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.

As previously mentioned, Valdosta Utilities and Valdosta Stormwater do not seem to agree on creek names. WWALS uses the names from Stormwater Division’s Master Stormwater Management Plan.

Valdosta Utilities also uses the St. Augustine Road culverts as an upstream testing location for Sugar Creek. Actually, that’s upstream of Sugar Creek, but that location is on Hightower Creek.

Here you can see where One Mile Branch and Hightower Creek separately flow into Sugar Creek.
