Hamilton County Planning Commission wants conditions on Nutrien phosphate mine permit renewal 2023-03-28

Update 2023-04-13: More materials: Hamilton County Planning Commission on Nutrien phosphate mine permit renewal 2023-03-28.

Update 2023-04-12: The County Commission meeting will be April 18th.

The Nutrien Phosphate Mine in Hamilton County, Florida, is up for renewal by the Hamilton Board of County Commissioners on Tuesday, April 28 18, 2023, at 6 PM. There will be a Public Hearing. Since time to speak will be limited, best to send written comments in advance.

The renewal request has already been reviewed by the Planning and Zoning Board (PNZ), on March 28, 2023. PNZ recommends renewal with some conditions.

Private landowners, a number of whose property is inside the mine boundary, object that some of Nutrien’s plans for disposal of waste such as clay will adversely affect those landowners’ businesses as well as wildlife and waters.

Dennis J. Price, P.G., of Hamilton County filed a page of questions.

Bienville Outdoors filed a a request to find other options for settling areas.

Maybe you would like to comment on effects of this mine on the Suwannee River, Swift Creek, the Floridan Aquifer, or public health.

Gibson Park to Suwannee River State Park, swim view Five Holes, 2022-08-13

A summer saunter on the iconic Suwannee River, with swimming in viewing the connected sinks and springs of Five Holes.

According to the Park, Five Holes is closed for renovation, but we have permission from Park Manager Matt Phifer to swim in view Five Holes on this outing.

There may or may not be swimming through some of the holes if you know what you’re doing. If the water is low like now, you can see through and it will be a walk through. But there are no dark spots; the main danger with swimming is banging your head.

When: Gather 9 AM, launch 10 AM, end 2 PM, Saturday, August 13, 2022

Put In: Gibson Park Ramp, 6844 SW CR 751, Jasper, FL 32052. Right bank, west side of the river. From Jasper, Hamilton County, FL, travel southwest on Right bank. SW CR 249 to SW CR 751; turn left and boat ramp is on the right in Gibson Park.

GPS: 30.437637, -83.094031

Take Out: Suwannee River State Park Ramp

Bring: the usual personal flotation device, boat, paddles, food, drinking water, warm clothes, and first aid kit. Also trash pickers and trash bags: every WWALS outing is also a cleanup. Mosquitoes can be bad at dusk so come prepared.

Free: This outing is free to WWALS members, and $10 (ten dollars) for non-members. You can pay the $10 at the outing, or online:

US 41 Little Alapaha River Bridge

Actually, there is a US 41 Little Alapaha River bridge, and it may even be historic. So that’s five bridges across the Little Alapaha River, four above the Swallet, and one below, before its Confluence with the Alapaha River.

[Composite US 41 Little Alapaha River Bridge]

The US 41 bridge is the first bridge listed by bridgereports.com for Hamilton County, mislabled as “US-41 (SR-6 & 25) over ALAPAHA RIVER OVERFLOW”. But at 30.52389, -83.01550, it’s much closer to the Little Alapaha River.

At more than a mile east of the Alapaha River, that’s a bit far to be overflow. Continue reading →

Groundwater considered important: WWALS to EPA 2022-02-07

WWALS sent EPA some comments on groundwater, which is very important here above the Floridan Aquifer in south Georgia and north Florida.

WWALS also signed on to comments by Waterkeeper Alliance and SELC, but SELC wrote almost nothing about groundwater, and there was more to say than was in the WKA comments. Those other comments are on the WWALS website.

The WWALS comments should appear on regulations.gov, Docket number EPA-HQ-OW-2021-0602, with Comment Tracking Number kzd-8bdc-p6xf, after EPA finishes reviewing it. Here they are in PDF and inline below.

Little Alapaha River, Swallet, Bridges, Source, Mouth 2022-02-07

Update 2022-02-09: US 41 Little Alapaha River Bridge.

During Sunday’s paddle on the last stretch of the Alapaha River, people got curious about a distributary which turned out to be the Little Alapaha River absorbing water from the Alapaha River.

Cold but well worth it, said the nineteen paddlers let by Shirley Kokidko on the WWALS paddle from US 41 on the Alapaha River to the Suwannee River. Plus a distributary that turns out to be the Little Alapaha River. And the Alapaha River Rise, where Alapaha River water from the Dead River Sink comes back up 20 miles and three days later, slightly upstream on the Suwannee River.

Sullivan Slough and Blue Sink by Amanda Davis 2022-01-18

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.

Blue Sink, Sullivan Slough –Susan Liden 2021-01-18

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!

Chervil Drive Distributary, Withlacoochee River 2022-01-13

Update 2022-01-21: Blue Sink, Sullivan Slough –Susan Liden 2021-01-18.

Another Withlacoochee River distributary to a sinkhole! This one revealed by WWALS member and archaeologist Tom Baird. I’m calling it Chervil Drive Distributary because we don’t know any more traditional or official name for it. It’s downstream from the Chitty Bend East Distributary and on the other side of the river.

Another interesting feature is further down river on the right bank about a mile above Madison Blue Springs. At flood, water pours through a gap in the limestone bank and floods a large channel that goes back to a deep sink. The weight of water in the past broke through the ceiling of a cavern and created a beautiful, clear, good-sized swimming hole. It was evidently a popular swimming and picnic spot in the past. Don’t know the correct name of the feature; my wife and I call it “Thanksgiving Spring”, because we found it while hiking around one Thanksgiving Day. However, it’s not a spring (no water comes from it), but an opening to the water table. Nice and cool on a hot day. J

Chitty Bend East Distributary, Withlacoochee River –Shirley Kokidko 2022-01-07

Update 2023-08-27: Pictures: Sullivan Launch to Florida Campsites, Withlacoochee River 2023-07-15.

River scout Shirley Kokidko went to investigate Mystery: Withlacoochee River Distributary 2021-01-01 and came back with these pictures from Friday, January 7, 2022.

Remember: it’s not safe to paddle in there.
