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 →

Very clean Thursday, Withlacoochee River 2021-02-25

Update 2021-03-05: More contamination after big rains, Withlacoochee River 2021-03-04.

The Bachrachs got something we haven’t seen for a long while on the Withlacoochee River: zero E. coli in their water samples at Nankin and State Line Boat Ramps, for Thursday, February 25, 2021. Madison Health got almost as low numbers for the same day at State Line, Sullivan Launch, and FL 6. Madison Health got almost as low numbers for Tuesday, and new WWALS testers Gus Cleary got even lower at NE Withla Bluffs Way downstream from Allen Ramp.

Valdosta got clean upstream for last Monday and Friday a week ago, and Michael and Jacob Bachrach and Gus got clean downstream for that Friday.

So this has been a clean week, the cleanest we’ve seen in a long while. Apparently all that rainwater has finally diluted and washed downstream any previous contamination.

Happy boating, fishing, and swimming!

But beware: with the rivers in flood stage, if you’re not an expert, avoid them still. Even if you are an expert, wear your PFD and don’t go alone. 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 →

Not looking good, Withlacoochee River 2021-02-16

Update 2021-02-21: Clean downstream Friday Withlacoochee River 2021-02-19.

As usual, heavy rains washed contamination into the Withlacoochee River, first detected by Madison Health Tuesday at State Line and FL 6, although oddly Sullivan Launch @ CR 150 was within the one-time sample limit for E. coli.

The good news: with so much rain, the contamination will probably be diluted and washed downstream rapidly.

The bad news: more rain likely coming. And there’s more cattle manure that can wash down Okapilco Creek into the Withlacoochee River. Plus with the Withlacoochee River rising in Valdosta, and more rain falling on Valdosta and Quitman, will we see manhole sewage spills?

We hope to have WWALS results for today ready by tomorrow (Friday), and most likely FDEP will publish Madison Health results, as well. Possibly even Valdosta will publish their Wednesday results by Friday.

We also have a surprising spot check in Drexel Park, and Valdosta’s last week results, which fit with the Madison Health and WWALS results. 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.

Yesterday afternoon FDEP posted Madison Health results for Thursday, February 11, 2021, and they were very bad: Continue reading →

Advisory lifted, Withlacoochee River, but big rains Tuesday 2021-02-09

Update 2021-02-13: Very bad, GA-FL line and downstream, Withlacoochee River 2021-02-11.

Madison and Hamilton Health on February 10th lifted their bacterial advisory of January 18th for the Withlacoochee River, due to good Florida water quality results for Tuesday. But there were big rains Tuesday, so conditions may have already changed, and not for the better.

This was after Madison Health got clean results Tuesday (yellow highlights), matching clean results last Thursday, at the GA-FL line, Sullivan Launch, and FL 6. Continue reading →

Clean Forty Miles, Withlacoochee River 2021-02-04

Update 2021-02-11: Advisory lifted, Withlacoochee River, but big rains Tuesday 2021-02-09.

The Withlacoochee River tested clean at sites forty miles from US 41 to the state line on Thursday, February 4, 2021, in WWALS tests. We have no new data downstream, but chances are it was clean there, too. Plus the Little River at Troupville Boat Ramp was clean. The rains predicted for yesterday and today have been underwhelming, so chances are the Withlacoochee was clean into Florida, too. So according to the data we have, the Withlacoochee River is good for boating, swimming, and fishing at least from US 41 in Valdosta, Georgia, to CR 15 in Florida. Which serves us right, after we rescheduled the big paddle for today until February 27. It’s cold out there, though, and rain is still predicted.

However, the bacterial advisory by Madison and Hamilton Health has not been lifted. We now have four clean test results at State Line: WWALS, Valdosta, Madison Health, and WWALS again. But they probably won’t lift the Florida advisory until they get two successive clean test results themselves. Since more rain is predicted most of the coming week, don’t be surprised if they either don’t lift it for more than another week, or lift it and then issue another a few days later.

Thanks to WWALS testers Michael and Jacob Bachrach, who got zero E. coli at Knights Ferry Boat Ramp, 33 at Nankin, and 133 at State Line Boat Ramp. Only that last one is above the 126 average test limit, and still well below the 410 one-time test limit. Continue reading →

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 →
