Still clean last week, filthy Friday before, Withlacoochee River 2021-03-26

Update 2021-04-03: Little Rain, Still Clean, Withlacoochee River 2021-04-01.

WWALS testers Conn and Trudy Cole found the Little and Withlacoochee Rivers still clean at two spots Friday after the WWALS clean results over thirty river mils Thursday. Crooked Creek was dirty Friday as it often is; see below.

Valdosta upstream Monday and Wednesday data concurs: clean.

There was a bit of rain yesterday (Sunday), but not much, so cleanliness probably continues. Happy boating, swimming, and fishing!

The week before was not so clean after all. Continue reading

Clean Withlacoochee River 2021-03-25

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

Clean everywhere, according to five WWALS testers who sampled spots on 80 Withlacoochee River miles Thursday, plus two on the Little River and one on the Alapaha River.

The latest we have from Madison Health is for Tuesday, and from Valdosta is for Friday a week ago, but those were clean, too. There’s been little to no recent rain, so probably nothing bad has washed into the rivers.

Good news for this morning’s paddle from Troupville Boat Ramp to Spook Bridge that Scott James calls the Mayor’s Paddle.

Withlacoochee River still clean, Florida bacterial advisory lifted 2021-03-23

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

Update 2021-03-27: Clean Withlacoochee River 2021-03-25.

Better than expected! Madison Health not only found clean Withlacoochee River water at State Line, Sullivan Launch, and FL 6, they lifted the health advisory from back in February!

This is good news for the Mayor’s Paddle this Saturday, March 27th, from Troupville Boat Ramp to Spook Bridge. Very little rain is predicted before then, and river levels are also good. We will test again Thursday (tomorrow) just in case.

Apparently we were too cautious last week. If the rains last Thursday had any effect on the river, it all got diluted or washed downstream by Tuesday.

After the clean results from the Bachrachs and Madison Health Thursday, we also got for Friday the cleanest result from Gus Cleary downstream from Allen Ramp: zero E. coli. Also Friday, Valdosta’s upstream results for US 41, GA 133, and US 84 were pretty clean. 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.

All clear, Withlacoochee River 2021-03-11

Update 2021-03-19: Clean week despite rain, Withlacoochee River 2021-03-18.

A rare simple all clear for Withlacoochee River water quality: all good for boating, swimming, and fishing.

[Clean, good, go]
Clean, good, go

We seldom see test plates this clean. Gus Cleary got zero (0) E. coli colonies on any of his three test plates for Thursday, March 11, 2021. They don’t look much different from his control plate. Most importantly: no blue colonies with bubbles. That’s at his place downstream of Allen Landing.

Also for Thursday, Madison Health also got very clean results at State Line, Sullivan Launch, and Florida 6.

Upstream, the most recent we have from Valdosta is for Monday, but that was all clear at US 41, GA 133, and US 84. Since there has been no rain all week, probably the Withlacoochee River remains clean. Continue reading

Tifton, Ashburn spills, bad downstream 2021-03-03

Update 2021-03-13: All clear, Withlacoochee River 2021-03-11.

Tifton and Ashburn, Georgia spilled raw sewage, March 3, 2021, both from places that had spilled before. For once we may have actually seen some of that in downstream water quality results. But they could not have caused the extremely high test result at Knights Ferry Boat Ramp that same day, nor the bad results into Florida the next day: those were most likely the usual cattle manure.

[Ashburn, Tifton spills and water quality]
Ashburn, Tifton spills and water quality

The high Fecal coliform at US 41 and GA 133 on the Withlacoochee River that same Wednesday could have been from the Tifton spill on the New River upstream, and the high E. coli at GA 133, all in Valdosta’s thrice-weekly testing. It’s about 64 river miles from 2406 N. Ridge Ave. to US 41, and about 70 miles to GA 133, but with the rivers high and fast, it’s conceivable a spill that started in the early morning (or the previous evening) could have moved downstream that fast.

Or with rains over an inch closer upstream on the Withlacoochee River, something else may have washed into the river. Or both.

The only way to be sure would be DNA tests. Valdosta is supposed to be doing those as part of the Consent Order. We are looking forward to seeing results. Continue reading

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

Year in review: water quality testing, February 2020-2021

Suzy Hall, WWALS Testing Committee Chair, pointed out that bacterial water quality results a year ago were generally worse than recently.

Results were awful for Monday, February 17, 2020 on the Withlacoochee.

[Awful KF, Nankin, SL 2020-02-17]
Awful KF, Nankin, SL, 2020-02-17

Suzy Hall filed Nankin Boat Ramp for Monday, February 17, 2020, as TNTC: Too Many To Count. Yes, that is a technical term, and you can see why: how many blue colonies with bubbles would you count?

Knights Ferry Boat Ramp wasn’t much better, at 8,933 cfu/100 mL. The Georgia Adopt-A-Stream high alert level is 1,000; see What do these numbers mean?. We have seen worse, namely the 39,000 Valdosta result at GA 133 on December 10, 2019.

But that was plenty bad enough.

Also, Valdosta later reported an even higher result for Knights Ferry for that same Feb 17, 2020, and Madison Health got horrible for the next day at State Line, Sullivan Launch, and FL 6.

For Wednesday, FDOH found a hot spot 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
