Thanks, Amanda Davis, for these pictures of Sullivan Slough and Sullivan Blue Sink.
Is it a sink or a spring? Probably a bit of each: a karst window, where the aquifer is exposed. So at high river water levels, the Withlacoochee River probably runs into it. At low river levels, water probably flows into the river.

Here’s where it ends up. Continue reading
Update 2022-01-28: Clean Rivers 2022-01-27.
I’d avoid the Withlacoochee River this weekend.
Bad E. coli levels upstream seen by Valdosta earlier in the week were still seen by WWALS upstream and down in Thursday samples. A too-high result at Hagan Bridge is heading downstream through Lowndes and Brooks Counties, Georgia. A too-high result at Knights Ferry is heading downstream to Florida.
The good news is no sewage spills have been reported this week. But it’s been raining yesterday and today, most likely washing more cattle and other manure into the river, down Okapilco Creek and from elsewhere.
If you want to paddle this weekend, I’d recommend the Alapaha River or upstream on the Suwannee River.

Valdosta’s downstream results for Monday and upstream for Wednesday were even worse than what WWALS got for Thursday. We don’t know about upstream Monday because Valdosta took a vacation. We don’t know about downstream Wednesday because Valdosta’s downstream contractor apparently hasn’t phoned home yet. Continue reading
Update 2022-01-21: Sullivan Slough and Blue Sink by Amanda Davis 2022-01-18.
Sullivan Slough is the real name of what we’ve been calling Chervil Drive Distributary, and Blue Sink is what local people call Chervil Drive Sinkhole.
Sullivan Blue Sink is where Withlacoochee River water ends up after flowing into Sullivan Slough, 0.83 miles downstream from Florida Campsites Boat Ramp, 0.73 miles upstream from the FL 6 bridge, and 0.83 miles up from Madison Blue Spring.
Traditionally, this has been a popular local swimming spot. However, the land containing the sink sold recently, so status is unclear now. We do have an offer from somebody with land nearby to tour the area.
Susan Liden sent these pictures. Thanks, Susan!
This one I think is particularly impressive. Continue reading
