Live Oak Sinkhole 2025-08-25

A sinkhole opened in U.S. 90 in the middle of Live Oak, Florida, yesterday. FDOT says it’s fixed since yesterday evening.

But chronic overpumping of groundwater produces such cavities, and increasintly big rains wash them open.

How Humans Affect the Aquifer, a WWALS Webinar, by Dennis J. Price, P.G., 2025-06-19

Dennis Price, P.G., of Hamilton County, Florida, says, “I plan on going through the history of surface and ground water in the flatwoods in south Georgia and north Florida in the Suwannee River Basin. Historic water levels and how we have changed these levels. Changes beginning with forestry then farming, and population growth. Ideas for correcting the problems.”

This applies to the Floridan Aquifer proper and the other aquifers above it, all below the Suwannee, Alapaha, and Withlacoochee Rivers, the Okefenokee Swamp, and their tributaries.

When: 12-1 PM, Thursday, June 19, 2025

Put In: Register to join with zoom:

WWALS Board Member Janet Martin will give a brief introduction.
Questions and answers will be at the end.

Waterkeeper Alliance advocates EPA and USACE restore longstanding protections for the nation’s waters 2025-04-23

Suwannee Riverkeeper, among 64 U.S. Waterkeepers, joined Waterkeeper Alliance and Environmental Integrity Project in asking the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers to maintain and restore longstanding protections for the nation’s waters.

[Waterkeeper Alliance advocates EPA and USACE restore longstanding protections for the nation’s waters 2025-04-23]
Waterkeeper Alliance advocates EPA and USACE restore longstanding protections for the nation’s waters 2025-04-23

Most of this long comment letter is applicable to the Suwannee River Basin. For example, related to the ongoing Georgia attempts to define which rivers and creeks are navigable: “lUnder the agencies’ Pre-2015 Regulatory Definition, all tributaries to traditionally navigable waters, interstate waters, impoundments, and ‘other waters’ are categorically defined as ‘waters of the United States.’” For example, see Valdosta sewage into Sugar Creek and Quitman sewage and cattle manure into Okapilco Creek, both into the Withlacoochee River in Georgia, upstream from Florida and the Suwannee River.

The comment doesn’t mention the Floridan Aquifer, but there are mentions of “Large numbers of rivers and streams… that briefly flow subsurface and then reemerge as surface waters.” and river-connected “subsurface flows and springs” elsewhere. Subsurface flows are important in the Suwannee River Basin and the Floridan Aquifer.

The Florida Basin Managment Action Plans (BMAPs) supposedly intend to reduce by 85-95% the leaching of fertilizer nitrates through the soil and subsurface limestone into springs and rivers, causing algae blooms and crowding out native vegetation, to the detriment of manatees and other wildlife.

River water and groundwater interchange interacts with drinking water treatment 2025-03-26

We all drink with straws from the groundwater here in the U.S. southeast coastal plain.

So surface water interchange with groundwater produces problems for city and county drinking water treatment, and for E. coli contamination of private water wells. Continue reading

Pictures: Waterkeepers Florida, Santa Fe River and springs 2024-02-08

We saw many springs, divers, entrances to two big sinkholes (Little and Big Awesome Sucks), many turtles, some alligators, a wood stork, a cattle egret, a hawk, a great blue heron, and some buzzards, as well as many gar and other fish, more cypress knees than you can count, and one very old cypress tree, just below some less than scary shoals.

Perhaps most importantly, nobody was in a hurry to get anywhere. Everybody paddled leisurely, took in the sights, and socialized.

At one of our Friday morning Waterkeepers Florida (WKFL) zoom calls, Jen Lomberk, the WKFL chair, asked Suwannee Riverkeeper to organize an outing while we would all be in Gainesville for an annual conference. The nearest Suwannee River Basin River is the Santa Fe, so I called on Doug Jipson of outfitter Rum 138 to shuttle us, and Merillee Malwitz-Jipson of Our Santa Fe River (OSFR) to guide us. See also the pictures Merrillee sent.

Waterkeepers Florida consists of all 15 Waterkeepers of Florida,
https://www.waterkeepersflorida.org

Waterkeeper is the generic name that includes Riverkeepers, all licensed by Waterkeeper Alliance. Suwannee Riverkeeper and St. Marys Riverkeeper are Waterkeepers of both Florida and Georgia.

Eleven WKFL members showed up (some with more than one representative), which is about the usual percentage for the annual gathering. Some of them had never seen a blue spring before. We went to Gilchrist Blue Spring, Devil’s Eye Spring, Ginnie Spring, and numerous more, between Rum Island and FL 47 Ramp in Gilchrist County Santa Fe River Park.

Actually, we were going to put in at Rum Island County Park, but it was mysteriously closed that morning. So we put in at Merrilee’s private river access.

When we got to Rum Island, the work at the park was obvious: the incredibly ostentatious orange barrier at the swimming area.

Here are some video snippets:

Exploring the Santa Fe River: Origins –Joanne Tremblay 2023-11-03

Joanne Tremblay says, “I was inspired to create a visual of the river’s path so folks could get a better understanding of its changes it goes through before it becomes the spring-laden stretch that most are familiar with. All my own footage, paddles are a composite from my own at different times.”
