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 →

Tifton Sewage Spills 2021-02-16

Update 2021-02-26: And more Tifton spills, two days later; Tifton Spills, Little River, New River 2021-02-18.

Update 2021-02-21: Nothing obvious related to the Tifton spills in downstream testing; see Clean downstream Friday Withlacoochee River 2021-02-19.

The City of Tifton spilled three places, for a total of 35,500 gallons of raw sewage, Sunday and Tuesday, February 14 and 16, 2021. Why? “Wet weather.” It’s true that an inch of rain fell on Tifton Saturday, an inch and a half Sunday, and almost another inch Tuesday.

Any spill is too many. However, these were all so far upstream that probably will not show up in any of the downstream water quality testing currently going on. It would be good to get some testing on the Little River between Tifton and Reed Bingham State Park to see if Tifton Spills reach that park.

One spill location was repeated: Agrirama Lake, which drains into the Little River. Tifton previously spilled there in 2015, 2016, and 2018. See 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 →

Better, Withlacoochee River 2021-02-12

Update 2021-02-18: Not looking good, Withlacoochee River 2021-02-16.

WWALS samples Friday for Knights Ferry, Nankin, and State Line Boat Ramps were all well below the 410 one-time E. coli limit. So State Line was way below what Madison Health got for Thursday. I’m happy to have guessed wrong. So far as the most recent data we have, the Withlacoochee River is good to boat, swim, and fish at least as far as the GA-FL line.

But remember, it rained again today upstream. And there’s probably more manure that can be washed down Okapilco Creek into the Withlacoochee River. 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 →

Spook Bridge, Knights Ferry, Nankin, State Line: all good, Withlacoochee River 2021-01-31

Update 2020-02-06: Clean Forty Miles, Withlacoochee River 2021-02-04.

All my Sunday tests, from Spook Bridge (just below US 84) to State Line, were good, well below the 410 cfu/100 mL one-time E. coli limit. Spook Bridge and State Line were below the 126 average limit. But there are two catches: rain and downstream. So I wouldn’t go boating, swimming, or fishing until I see more test results. The Madison and Hamilton Health bacterial advisory is still in effect, and will probably remain so until they see two sets of clean Florida tests.

The catch: the contamination Suzy Hall’s Sunday WWALS test still showed Saturday at State Line must have washed downstream. We have no new tests from Madison Health yet. They probably tested today (Tuesday), so maybe we’ll get those tomorrow. Continue reading →

Bad State Line, Withlacoochee River 2021-01-30

Update 2021-02-02: Spook Bridge, Knights Ferry, Nankin, State Line: all good, Withlacoochee River 2021-01-31.

Suzy Hall tested for WWALS Saturday at State Line Boat Ramp on the Withlacoochee River, and got 500 cfu/100 mL, which is well above the 410 one-time test limit. So I’d still avoid boating, swimming, and fishing in that water. I tested at four sites Sunday, so we’ll see if there’s any improvement. But beware more rain fell Sunday, so probably stay off the river for a few more days.

Suzy’s Saturday result is lower than the Thursday State Line results by the Duncans for WWALS and by Madison Health, but still not good. The Swim Guide map is unchanged. Continue reading →

Very bad, health advisory, Withlacoochee River 2021-01-28

Update 2021-02-01: Bad State Line, Withlacoochee River 2021-01-30.

Best avoid the Withlacoochee River for a few days. It rained more Wednesday than last Friday, and this time something definitely washed into the river, confirmed Thursday by both WWALS testers Josh and Angela Duncan and by Madison Health, published by FDEP. Madison and Hamilton Health have published a health advisory for the Withlacoochee River.

Given that more rain is expected Sunday, it might be prudent to stay off the river until sunny next week. Continue reading →
