WWALS Summary of FDEP chemical and biological tracers, Withlacoochee and Suwannee Rivers 2020-08-05

Here are the chemical tracer and DNA marker test results by the Florida Department of Environmental Protection (FDEP) that WWALS has frequently mentioned, for example in Current Situation of Water Quality Testing, Suwannee River Basin 2020-08-02.

Below, please also find a summary of those results by WWALS Science Committee Chair Dr. Thomas Potter.

Thanks to Katrina Yancey of FDEP for sending the data, and for acknowledging that FDEP has no objection to WWALS publishing it. I asked FDEP for whatever they wanted to include, and this is what they sent:

“Thank you for asking, we recently set up our new site so it may be helpful to state that more information may be found at DEP’s webpage for the Suwannee River Basin Sampling Locations (https://floridadep.gov/dear/watershed-monitoring-section/content/suwannee-river-basin-sampling-locations).”

The actual data is on the WWALS website.

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

Update 2020-08-18: Good upstream water quality, Little, Withlacoochee, Okapilco, worst Crooked Creek @ 2020-08-16

The Withlacoochee River looks good for boating, swimming, and fishing this weekend, according to the latest water quality testing results, despite a contamination incident earlier this week.

[Chart and Map]
Chart and Map

More than an inch of rain at Moultrie Monday washed E. coli down Okapilco River (as they call it in Colquitt County) and Wednesday Valdosta got very bad 2,800 cfu/100 mL E. coli on Okapilco Creek @ US 84 in Brooks County, and bad 400 on the Withlacoochee River @ Knights Ferry Boat Ramp in Lowndes County. See What do these numbers mean?

Yet downstream at Nankin Boat Ramp and State Line was good Wednesday according to Valdosta, and also good Tuesday and Thursday at State Line, CR 150, and FL 6 according to Madison Health, in data updated online by FDEP early afternoon Friday. WWALS testers Michael and Jacob Bachrach also got very good results Thursday at Knights Ferry and State Line.

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

So I’ve marked all Withlacoochee River “beaches” green on Swim Guide.

However, once again there was heavy rain at Moultrie, this time on Friday, so don’t be surprised if E. coli shows up on Monday or even Saturday on Okapilco Creek @ US 84 or Withlacoochee River @ Knights Ferry.

Meanwhile, heavy rains at Tifton way upstream on the Little River should be Continue reading →

Excellent water quality, Withlacoochee River, but raining now 2020-07-22

Update 2020-07-27: Alert bacteria level at GA 133, Withlacoochee River, Friday 2020-07-24.

Valdosta already reported downstream Withlacoochee River results for Wednesday! They are excellent: 30 cfu/100 mL E. coli for Okapilco Creek @ US 84, same for Knights Ferry and Nankin Boat Ramps, and 40 for State Line: all well below the 126 longterm average limit. Valdosta results for Friday and Monday were similar, so the longterm average is in fact excellent. Plus we have Thursday and Tuesday Florida results, none higher than 10 for any of GA 31 (State Line), CR 150 (Sullivan Launch), or FL 6 (Madison Blue Spring). All that backs up the zero WWALS tester Suzy Hall got at State Line Boat Ramp Saturday.

Upstream, the most recent results from Valdosta are 30 for US 41, 140 for GA 133, and 0 (zero) for US 84, which is as good as it gets.

However, the UGA station for Dixie, GA, on the west side of Brooks County, already reported more than an inch of rain. Not so much rain anywhere else, so we don’t know what that rain will wash to the waterways. WWALS will be testing this weekend.

All green to go, Withlacoochee River 2020-07-18

Update 2020-07-23: Excellent water quality, Withlacoochee River, but raining now 2020-07-22.

We don’t always get zero E. coli on the Withlacoochee River, but when we do, we like it!

That’s zero cfu/100 mL at State Line Boat Ramp Saturday, by WWALS tester Suzy Hall, and zero at FL 6 just above Madison Blue Spring Tuesday by Madison Health. With below 410 (that’s good) everywhere upstream in Valdosta Monday, Wednesday, and Friday results.

Plus, we have good results on the Alapaha River, thanks to WWALS testers Tasha Ekman LaFace and Suzy Hall.

[Green on Swim Guide, Withlacoochee River]

Yes, even Knights Ferry and Nankin Boat Ramps showed good results all week. We didn’t know that until today, but now we do, thanks to Valdosta PIO Ashlyn Johnson getting those numbers posted about 1PM today. Continue reading →

Lifted: Florida Withlacoochee River Bacterial Advisory 2020-07-15

Update 2020-07-20: All green to go, Withlacoochee River 2020-07-18.

Going by the good downstream Florida results FDEP posted yesterday for Monday, July 13, shortly before Tom Mirti announced those results in the SRWMD Board meeting yesterday, as he predicted, Madison and Hamilton Counties, Florida, Health Departments today lifted the bacterial advisory they posted last Thursday. Not much rain has fallen lately, so results will probably stay good downstream until the next big rain.

So I’ve marked State Line Boat Ramp and the Florida “beaches” green on Swim Guide.

[Green State Line and Florida in Swim Guide]
Green State Line and Florida in Swim Guide

We have good Valdosta Monday results for US 84 and upstream, but nothing downstream yet, so Knights Ferry and Nankin Boat Ramps remain red. Since there’s been no significant rain lately, and results are good upstream and downstream, chances are Knights Ferry and Nankin are also good, but we can’t change Swim Guide for them until we get new test results.

Bad Knights Ferry in Valdosta data down to state line, Monday and Wednesday 2020-07-08

This very high Valdosta Monday 1,600 E. coli data for Knights Ferry Boat Ramp and even higher 3,200 for Nankin Boat Ramp help explain the Florida high result downstream on Tuesday, which itself helped explain yesterday’s Florida bacterial alert for the Withlacoochee River.

[Valdosta Monday and Wednesday results]
Valdosta Monday and Wednesday results
For the complete WWALS composite spreadsheet of Georgia and Florida results and other context, see wwals.net/issues/testing/.

For how bad those numbers are, see What do these numbers mean?

Valdosta’s Wednesday Nankin result was better, and its Knights Ferry 570 result at least wasn’t as horrible, although that was still higher than the one-time sample 410 limit. Yet Okapilco Creek @ US 84 had actually gotten worse.

So we can hope the Florida downstream good results are a good indicator. But there could be more E. coli still coming down the Withlacoochee River.

WWALS testers are collecting samples today and tomorrow, so we shall see.

Meanwhile, we have to put Knights Ferry Boat Ramp back to red on Swim Guide, because that’s the most recent data we have for it. Nankin just barely squeaks by under 410, so it’s green like all the eight Withlacoochee River “beaches,” except Knights Ferry.

Thanks to Valdosta PIO Ashlyn Johnson for getting this Valdosta downstream data published. Maybe that can become standard practice, so people will have a better idea of river conditions before the weekend. This is in Valdosta’s own interest, since it usually shows Continue reading →

Data behind and after Florida bacterial advisory for Withlacoochee River 2020-07-09

Update 2020-07-10: Bad Knights Ferry in Valdosta data down to state line, Monday and Wednesday 2020-07-08.

Update 2020-07-10 13:00: FDEP Thursday data has been posted, with results back within normal bounds.

Today FDEP posted FDOH data from Tuesday, which shows 471 cfu/100 mL E. coli at CR 150 (Sullivan Launch). Presumably this is what provoked yesterday’s bacterial advisory for the Withlacoochee River from Madison and Hamilton County Health Departments.

[Bad at CR 150, increasing upstream]

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

Thanks to Valdosta PIO Ashlyn Johnson, Valdosta also published Wednesday data, which shows higher E. coli readings than usual, higher than the 126 geometric average limit, although still below the 410 single-test limit. See What do these numbers mean?

Update 2020-07-10 13:00: Actually, with the FDEP Thursday data, Swim Guide is all green again for the Withlacoochee River in both Georgia and Florida. And the Little River, too, since we have no updated data yet. We’ll have at least one datapoint collected today or tomorrow on that.

I was mistaken about the WWALS samples for Crooked Creek: those are being collected today, along with some others today and tomorrow. I still won’t be surprised if they’re high in E. coli, although since the rains seem to have died down, I also won’t be surprised if the contamination has already flushed downstream and maybe even been diluted.

But we don’t know. Especially that part about downstream of FL 6: nobody is testing down there.

Floridians, you may want to ask your statehouse delegation and FDEP and other appointed officials to fund and implement regular, frequent, water quality testing all the way to the Gulf. If Valdoosta, GA, can do it on forty river miles to the state line, the great state of Florida can do it.

Oh, and it would help if Valdosta would post its results to the state line a bit more speedily.

Possible bacterial contamination, Withlacoochee River, Hamilton, Madison Co. FL 2020-07-09

Update 2020-07-10: Data behind and after Florida bacterial advisory for Withlacoochee River 2020-07-09.

It’s a Florida Health Department advisory of possible bacterial contamination, so I have set the four Florida Swim Guide “beaches” to red: Sullivan Launch, Florida Campsites, Madison Blue Spring, and Madison Ramp. However, since the advisory only says “Elevated indicators of fecal bacteria” without saying what those indicators are, and I can find no actual data, I have left the Georgia “beaches” green for now: US 84 Landing and Knights Ferry, Nankin, and State Line Boat Ramps.

[Swim Guide: red Withlacoochee River in Florida]

Here’s the advisory, received today at 4:38 PM.

Until further information is known regarding possible bacterial contamination of the river, people in the area are urged to take precautions when in contact with the Withlacoochee River. The Florida Department of Health and the Department of Environmental Protection are conducting water sampling.

Indeed, little seems to be known.

I can only guess Madison and Hamilton Health Departments are concerned by all that rain upstream for the past week. That does usually wash E. coli into the Withlacoochee River. Continue reading →

Florida lifts Withlacoochee River advisory; more rain could mean more contamination 2020-06-11

Update 2020-06-16: All eight Withlacoochee River landings green 2020-06-14

Valdosta’s Wednesday Knights Ferry result is not pretty: 2,300 cfu/100 mL E. coli, far over the 1,000 alert limit. Previously, I said we wouldn’t turn Swim Guide green until we saw that result. Plus, much more rain fell Friday on Lowndes and Brooks Counties, Georgia. Also, Valdosta got 1,500 on Okapilco Creek at US 84, even worse than the 833 I got there that same Wednesday (see yellow highlighted area).

So, Swim Guide stays red for the Withlacoochee River in Georgia. But Swim Guide goes green for Florida; see below. See also below for the Little and Alapaha Rivers.

WWALS will test tomorrow. You can help.

Florida, and Upstream water quality tests for Lowndes and Brooks Counties, GA 2020-06-10

Update 2020-06-13: Florida lifts Withlacoochee River advisory; more rain could mean more contamination 2020-06-11.

The Withlacoochee River from the state line to the Suwannee River looked much better Wednesday, according to FDEP results.

Upstream on the Withlacoochee and Little Rivers and two out of three creeks in Brooks County, not so good, according to samples I took Wednesday.

Valdosta’s Wednesday results fill in US 41 (North Valdosta Road), GA 133, and US 84 on the Withlacoochee River. We await Valdosta’s Knights Ferry and Nankin Boat Ramp results.

Meanwhile, you can help.
