Floridan Aquifer Groundwater Pumping –Dr. Bob Knight 2026-05-09

1 Reply

Published with permission, here is what Dr. Bob Knight ferreted out from USGS and the WMDs about groundwater pumping.

You’d think they would publish this information, but since they didn’t, WWALS is.

These slides (PowerPoint or PDF) don’t say anything about Water First North Florida (WFNF), the WMD and JEA plan to pipe treated wastewater from Jacksonville into the Suwannee Basin, but this is the groundwater background to WFNF.

He sent these slides to various environmentalists on May 9, 2026, with this note. I asked him later in person if he minded WWALS publishing. He said go ahead.

Attached is an updated summary of Florida groundwater wells, permits, and reported extraction quantities from the Floridan aquifer. All data were provided by the water management districts and the USGS. But the summaries of those reams of data are my work and may not be complete and accurate in all cases. Surprisingly, the WMDs have differing data bases and few detailed summaries of these data. For now, I believe these may be the best data summaries out there. Historically (up to 2015) Richard Marella formerly with USGS reported a lot of Floridan aquifer detailed/summary data every five years. That important contribution ended in 2015 and there is no sign that it will be picked back up by the state or the USGS.

The inconvenient truth is that all groundwater extractions reduce spring flows and that data analysis indicates that the ratio is almost one to one. Measured spring flow reductions closely mirror these reported pumping totals and differ widely from groundwater flow model estimates.

Please let me know if you have any questions.

Best wishes,

Bob

Phase II Water Shortage and Springs Protection Awareness Month Proclamation @ SRWMD 2026-03-10

Update 2026-03-10: SRWMD livestreams its meetings on YouTube. This one will be here: https://www.youtube.com/watch?v=RXdoI5qrgXQ

There is nothing on the SRWMD Board agenda about Water First North Florida (WFNF) for 9 AM this Tuesday, March 10, 2026. But there are several items related to that scheme to pipe treated wastewater from Jacksonville into the Suwannee River Basin.

If you can, please do go to the SRWMD meeting and speak. Don’t forget these other meetings:

The SRWMD agenda for tomorrow has a Public Hearing about declaring a Phase II Severe Water Shortage. That declaration is watered down, with few actual requirements. Although not as much as the Modified Phase II Severe Water Shortage already declared by SJRWMD, which appears to eliminate all mandatory water restrictions.

Also on the SRWMD agenda, perhaps ironically, are

  • a “Water Conservation Month Proclamation” and
  • a “Springs Protection Awareness Month Proclamation”.

And of course the monthly SRWMD Hydrologic Conditions Report, which will detail how bad the drought is.

Plus you never know what will be presented in “WATER RESOURCES, Amy Brown, Deputy Executive Director, 9. Water Resources Division Updates.” Continue reading →
