Much cleaner: Withlacoochee River 2021-04-29

Update 2021-05-03: Still clean Friday: Withlacoochee River 2021-04-30.

Despite a Quitman sewage spill last weekend, the Withlacoochee River was already much cleaner Wednesday, as found by WWALS tester Gus Cleary at Cleary Bluff below Allen Ramp. He got similar results for Thursday, confirmed by Valdosta’s upstream results for Wednesday, and Madison Health’s Florida results for Thursday.

How can this be? The massive upstream rains Saturday are coming down the rivers now, washing the contamination downstream and diluting it.

While Madison and Hamilton Counties, Florida, will probably leave their health alert in place until they get a second clean set of Florida results, I’d feel comfortable now with boating, swimming, or fishing in the Withlacoochee River.

I’d still wait a day or so for the Suwannee River downstream of the Withlacoochee.

We don’t have any new data for Knights Ferry or Nankin Boat Ramps (our usual testers are off this week, after discovering this problem Monday). So those two locations still show Continue reading

Health alert for Withlacoochee River 2021-04-27

Update 2021-04-30: Much cleaner: Withlacoochee River 2021-04-29.

Received 4:17 PM yesterday, April 28, 2021: “The Florida Department of Health in Hamilton and Madison counties have issued a health alert for the Withlacoochee River, April 28, 2021.”

That was after FDEP published the Madison Health downstream results for Tuesday, which, while not as bad as the WWALS results for Monday, were still above the 410 colony-forming units per 100 mililiter (cfu/100 mL) limit for of E. coli in a single sample.

The cause? Very likely agriculture, as in cattle manure, maybe horses, likely some wild hogs, plus cats, dogs, chickens, deer, and sheep. No, it’s almost certainly not the tiny and mostly-vacuumed Valdosta FOG Manhole sewage spill of Monday. Don’t be surprised if spills from elsewhere start showing up last on the GA-EPD Sewage Spills Report. But those still probably won’t be the main problem, given how widespread the contamination is.

The good news is still that Continue reading

Clean week despite rain, Withlacoochee River 2021-03-18

Update 2021-03-29: Still clean last week, filthy Friday before, Withlacoochee River 2021-03-26.

Update 2021-03-24: Withlacoochee River still clean, Florida bacterial advisory lifted 2021-03-23.

Surprisingly, the results Michael and Jacob Bachrach got today, for the samples they collected yesterday after the rains, were almost as clean as possible at Knights Ferry and State Line, and really as clean as possible at Nankin Boat Ramp: zero (0) E. coli.

This matches what Madison Health saw at the state line, Sullivan Launch, and FL 6 yesterday, presumably just before the rains. And with what Madison Health and Valdosta saw earlier in the week.

It’s surprising because we expected Continue reading

Florida needs water quality testing and sign posting

Florida needs to test our rivers all the way to the Gulf, several times every week, instead of depending on Madison County and the city of Valdosta and WWALS.

Jim Tatum caught me and Merrillee Malwitz-Jipson collaborating, probably about getting FDEP to do the DNA marker and chemical tracer tests that have been instrumental in showing most of the recent Withlacoochee River contamination has come from ruminants, of which the most numerous are cattle.

Calusa Riverkeeper John Cassani knows I bring up the need for statewide Florida testing at almost every weekly Waterkeepers Florida meeting, after he mentions testing where he is.

More contamination after big rains, Withlacoochee River 2021-03-04

As usual, the big rains washed more contamination into the Withlacoochee River, most likely mostly down Okapilco Creek from cattle in Brooks County, Georgia.

However, since the rains were Monday and Tuesday, by the time Madison Health and WWALS tested Thursday, much of it had already started washing downstream. By Thursday it appears to have already been flushed down to the state line and beyond by more rainwater. By now it’s probably down into the Suwannee River, where it may well have been diluted by even more rainwater coming down the Alapaha and Suwannee Rivers.

So above the state line the Withlacoochee is probably OK to boat, swim, and fish this weekend. It may even be safe below the state line by Saturday morning, although we have no data on that.

So on Swim Guide I’ve set red from the state line down into Florida, yet green at Knights Ferry and Nankin Boat Ramps, as well as green for Valdosta’s readings upstream Monday before the rains.

The 3,784 cfu/100 mL E. coli Madison Health got at Florida 6 Thursday is far higher than the 1,000 alert limit. But a year ago on Thursday, March 5, 2020, Madison Health got TNTC (Too Numerous To Count) at all three of State Line, Sullivan Launch, and Florida 6. Plus that Friday Valdosta got 4,600 at the state line and 25,000 at Knights Ferry Boat Ramp. So there is still ample room for improvement, but it’s possible that the Best Management Practices (BMPs) the Brooks County dairies have been implementing are starting to work. Continue reading

Clean downstream Friday Withlacoochee River 2021-02-19

Update 2021-02-26: Very clean Thursday, Withlacoochee River 2021-02-25.

Good news downstream on the Withlacoochee River!

Madison Health reported good downstream numbers for Thursday, February 18, 2021, despite more than an inch of rain at every gauge we follow. WWALS testers confirmed that for Friday, with good results from Nankin Boat Ramp to below Allen Ramp. It looks like rainwater from upstream is finally diluting and washing down the contamination downstream rain put into the river.

We also see no obvious signs of contamination from the last Sunday and Monday Tifton sewage spills, which is not unexpected since they were so far upstream. We don’t know what effect the one upstream of the Little River might have had on Reed Bingham State Park, because we have no volunteers to test that stretch.

The weather is looking good for the Mayor’s Paddle from Troupville Boat Ramp to Spook Bridge on Saturday, February 27, 2021. It didn’t rain yesterday, and the only rain predicted for the next week is for Monday. So risks of contamination are low. However, the rivers are very high, still expected to be ten feet higher than we’ve ever paddled that stretch before. That’s not necessarily a problem for paddling, because it’s a long wide stretch with no real risks of getting lost in the floodplain, no deadfalls, and few overhanging branches. However, we will have to check to see if we can even get in by land at Spook Bridge and the midpoint, not to mention at Troupville Boat Ramp. The US 84 gauge prediction is 107 feet NAVD 88 for Thursday, which is about 27 feet higher than when we rescheduled Thursday three weeks ago. We will go look and let you all know. Continue reading

Very bad, GA-FL line and downstream, Withlacoochee River 2021-02-11

Update 2021-02-13: Better, Withlacoochee River 2021-02-12.

I’d avoid the Withlacoochee River for a few days if I were you. Apparently the Tuesday rains did wash more manure out of Brooks and Colquitt Counties down Okapilco Creek into the Withlacoochee River.

Valdosta’s Wednesday results upstream of Okapilco Creek were only slightly elevated, but Madison Health’s Thursday downstream results were very high. The WWALS Thursday samples had a technical glitch, so we don’t know about Knights Ferry or Nankin Boat Ramps, but they were probably pretty bad. We hope to have Friday results soon.

Meanwhile, I would not want to get that river water on me until the upstream rainwater dilutes and washes down the contamination, which will probably take a few days. Unless, of course, it rains harder and washes more in.

Bad Friday after rain, Better Sunday, Withlacoochee River 2021-01-24

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.

Apparently the Withlacoochee River is clean again, although we do not have many datapoints yet. Be warned more rain is expected today. Continue reading

Withlacoochee advisory lifted; more FDEP DNA marker and chemical tracer data 2021-01-12

Update 2021-01-21: Clean Withlacoochee 2020-01-14 and Suwannee River tests 2021-01-18.

It’s lifted: the bacterial advisory from Madison and Hamilton Health Departments, because of two successive good sets of results from Madison Health on the Withlacoochee River, the lastest for Tuesday. And Valdosta got good results upstream for Monday. All of which corroborates the Thursday Madison Health, Friday Valdosta, and Saturday WWALS results.

We also have more DNA marker data from FDEP, for Wednesday, January 6, 2021, which shows continued high ruminant DNA marker results on the Withlacoochee River, this time for Horn Bridge at the State Line, plus CR 150 at Sullivan Launch, and FL 6 just above Madison Blue Spring. Plus some clarifications of what I wrote in the previous blog post.

Before we get into all that, happy boating, swimming, and fishing on the Withlacoochee River! Continue reading

Contaminated Withlacoochee, Alapaha, Suwannee Rivers 2021-01-04; cleaner 2021-01-09

Update 2021-01-14: see clarifications and updates in Withlacoochee advisory lifted; more FDEP DNA marker and chemical tracer data 2021-01-12.

The Withlacoochee, Alapaha, and Suwannee Rivers were contaminated with E. coli Monday, January 4, 2021, all the way from US 41 at North Valdosta Road to US 90 below the Withlacoochee River Confluence, and probably farther downstream, according to Valdosta, Madison Health, and FDEP data for that day. We also have preliminary DNA marker results from FDEP.

The culprit? Ruminants. The only ruminants numerous enough to cause the sky-high DNA marker results for the Withlacoochee and Suwannee Rivers? Cattle.

This is a good example of how when testing happens upstream and down, we can all tell what is going on. Florida needs to fund frequent, regular, closely-spaced water quality testing from the state line to the Gulf. Continue reading
