Health Advisory, Withlacoochee River, State Line 2020-10-02

Update 2020-10-06 Two or more sources last Tuesday, advisory lifted Monday, Withlacoochee River 2020-10-05.

A Health Advisory was isssued today by Madison and Hamilton Counties, Florida, for fecal bacteria in the Withlacoochee River, apparently based on a too-high water quality test result at the GA-FL line on Thursday (yesterday). As that washes downstream, it’s probably best to avoid the river. Upstream, Valdosta reported a too-high reading at GA 133, and that is probably also washing down the river, so this is not a good weekend for boating.

GA 133 and Knights Ferry in 2.5 weeks of Valdosta and Florida water quality data 2020-09-24

Update 2020-10-02: Health Advisory, Withlacoochee River, State Line 2020-10-02.

Mostly all clear on the Withlacoochee River in a bunch of data Valdosta and FDEP posted recently, except a bad reading at Knights Ferry Friday a week ago, and yet again a problem at GA 133 this past Monday.

The latest (Wednesday by Valdosta and Thursday by Madison Health) indicates good quality for this weekend. Since there has been hardly any rain to wash anything into the river, all the WWALS Withlacoochee River “beaches” remain green on Swim Guide.

Happy boating, so far as we can see!

Valdosta’s new data goes back two and a half weeks downstream, and FDEP filled in Tuesday a week ago as well as this Tuesday and Thursday.

Bad far upstream and far downstream: Withlacoochee, Clyatt Mill Creek, Suwannee, Santa Fe 2020-09-21

Update 2020-09-26: GA 133 and Knights Ferry in 2.5 weeks of Valdosta and Florida water quality data 2020-09-24.

The most diverse set of testing data ever! It’s not bad upstream on the Withlacoochee River, but worse the farther down the Suwannee River, and, surprisingly, also the Santa Fe River.

[Rivers and Results]
Rivers and Results

Valdosta has reported for upstream on the Withlacoochee River for last Wednesday (good) and Friday (bad at GA 133, good at US 84).

Suzy Hall reported for WWALS at Clyatt Mill Creek (not bad, and thanks Langdale Company), and on the Suwannee River at Gibson Park (good for E. coli but very puzzling) and Anderson Spring Launch (good).

Loretta Tennant reported for WWALS on the Santa Fe River at Lemmons Ramp (alert!) and on the Suwannee River at Ivey Metropolitan Park in Branford (bad) and at Yellow Jacket Ramp between Manatee Springs and Fowlers Bluff (horrible). That’s enough to make us wonder if some of what’s getting into the Lower Suwannee River might be coming from the Santa Fe River.

We have no new data from FDEP or other Florida government agencies. Floridians, maybe you’d like to ask your elected and appointed officials for more water quality testing, especially downstream where we’re finding these bad results.

Meanwhile, all the WWALS “beaches” on Swim Guide remain green. That’s because we don’t have as beaches GA 133 on the Withlacoochee River nor as yet anything on the Suwannee River.

Update 2020-09-18: OK Withlacoochee River Quality, sewage spill Suwannee, FL, Suwannee River 2020-09-17

Sunday, Suzy Hall tested for WWALS at Sullivan Launch @ CR 15 on the Withlacoochee River, and got good results.

This despite a report of cows in a creek near the river just upstream in Hamilton County, Florida: that’s right, Florida, not Georgia.

Loretta Tennant’s WWALS results for the lower Suwannee were not so pretty.

And while Valdosta’s results for late last week corroborate those of WWALS and Madison Health, for Wedensday, September 2, Valdosta got bad results at State Line Boat Ramp.

Good downstream, but recurring GA 133, Withlacoochee River 2020-08-27

Update 2020-09-01: Valdosta concurs last week, but not week before, Withlacoochee River 2020-08-28

The good news: all WWALS results for Thursday were good downstream on the Withlacoochee River, and for Tuesday from Madison Health. So as far as we can tell, happy boating, swimming, and fishing this weekend on the Withlacoochee River.

The bad news: something is still getting into the Withlacoochee River above GA 133, and it does not seem related to rainfall. This bad news has been going on too long. It really needs to be resolved for the Troupville River Park.

Valdosta concurs: Withlacoochee River quality still looks good 2020-08-17

Update 2020-08-21 Looking clean downstream, Withlacoochee River 2020-08-20

Valdosta’s Friday and Monday results upstream and down concur with WWALS’ Sunday upstream results: the Withlacoochee River looks good for boating, swimming, and fishing. All such indications are merely advisory, of course, because water quality can change rapidly. There was rain upstream on the Little River Tuesday, but very little in Brooks County, so chances are good conditions will continue until there’s heavier rain.

Good upstream water quality, Little, Withlacoochee, Okapilco, worst Crooked Creek @ 2020-08-16

Update 2020-08-19: Valdosta concurs: Withlacoochee River quality still looks good 2020-08-17.

WWALS testers for Sunday after little rain found low water and good water quality upstream on the Little and Withlacoochee Rivers and Okapilco Creek in Cook, Lowndes, and Brooks Counties, Georgia, but very bad E. coli on Crooked Creek @ Devane Road in Brooks County.

[Green Swim Guide, pictures, results]
Green Swim Guide, pictures, results

Conn and Trudy Cole got 200 cfu/100 mL E. coli on the Little River @ GA 76 (Cook County Boat Ramp). That’s above the 126 long-term average limit, but still good enough to mark Cook County Boat Ramp green on Swim Guide. They remarked that’s the highest they’ve gotten there. Well, recently: back on April 25, 2020, after very heavy rain, they got 433, which is above the 410 one-time sample limit. That would be a red mark on Swim Guide, so it’s good they got 200 this time.

WWALS concurs, good to boat, Withlacoochee River 2020-08-06

Update 2020-08-15: Moultrie rain washed E. coli down Okapilco Creek; good now 2020-08-13

WWALS testers Jacob and Michael Bachrach also got good results from their Thursday samples: 66 cfu/100 mL E. coli at State Line Boat Ramp and zero (0) at Nankin and Knights Ferry Boat Ramps. Can’t get much better than that!

WWALS Testing Committee Chair Suzy Hall did remark that the Petrifilms for State Line showed quite a bit of other Fecal coliforms. But we can’t quantify those with the Petrifilm method, and we go by E. coli.

Of course, something else could have gotten into the river since Thursday. All of these results are always merely advisory.

But as far as we can tell, it’s a great weekend for boating on the Withlacoochee River!

[Good WWALS results, Knights Ferry, Nankin, State Line]

For context and the complete WWALS composite spreadsheet of Georgia and Florida results, see: https://wwals.net/issues/testing/

As you can see, the WWALS 66 at State Line was quite similar to the Madison Health 10. The Florida agencies use laboratories with more precision in their results than WWALS can get with Petrifilms: 66 is the lowest WWALS can show before zero.

These Thursday WWALS results at Knights Ferry, Nankin, and State Line corroborate what Valdosta got Wednesday at Knights Ferry, Nankin, and State Line, shifted downstream somewhat due to water flow and a day later. Note Valdosta got slightly higher results at Nankin Wednesday, and WWALS got slightly higher at State Line, which is about what we would expect from water flow.

Until the next big rain (or dumping or, we sure hope not, sewage spill), water quality will probably remain good.

GA 133 Friday bad again? But good everywhere else, Withlacoochee River 2020-08-06

Update 2020-08-08: WWALS concurs, good to boat, Withlacoochee River 2020-08-06.

The good news: all green for boating, fishing, swimming, etc. from Cook County Boat Ramp on the Little River @ GA 76 and on the Withlacoochee River from US 41 through the GA-FL line past Madison Blue Spring. Thanks to Madison Health and the City of Valdosta for testing, and to WWALS testers Trudy and Conn Cole for finding zero E. coli on the Little River @ GA 76 (Cook County Boat Ramp).

The bad news: last Friday, again there was massive fecal bacterial contamination in the Withlacoochee River @ GA 133, far higher than the 410 cfu/100 mL single-test limit and twice the 1,000 alert limit. See also What do these numbers mean?.

The better news: a usually reliable source tells me that GA-EPD has found the culprit and is dealing with it. And the culprit was not governmental; it was a private company. More on that when I know more.

[Map: All green on Swim Guide]
Map: All green on Swim Guide.

It’s really strange that such a high concentration of fecal bacteria at GA 133 did not show up downstream. Where did it come from? It’s not runoff: there was no rain, except way up at Skipper Bridge, which should have showed runoff contamination at US 41 before GA 133 if that was the source.

It’s not Valdosta or Lowndes County: they had no spills.

It’s almost like somebody dumped some septic tank or RV liquids into the river. Continue reading →

Twomile Branch and Withlacoochee River 2020-07-28

Update 2020-07-31: Just when you think it’s safe, nope, Withlacoochee River to GA-FL line 2020-07-29.

For Monday, July 27, 2020, Valdosta reports still slightly elevated bacterial counts at GA 133 on the Withlacoochee River, but nothing like the alert level of Friday. Yet counts at US 41 upstream and US 84 downstream remain completely normal. We can guess that rainwater coming down the Little River into the Withlacoochee diluted the contamination.

We don’t know where that Friday GA 133 contamination came from. Both Valdosta and Lowndes County say they did not spill any sewage, and the state of Georgia still reports no sewage spills in the Suwannee River Basin (ditto for Florida).
