Looks like we may finally see Action stage tomorrow on the Withlacoochee River above Valdosta @ Skipper Bridge Road. This is upstream from Valdosta’s Withlacoochee Wastewater Treatment Plant, so it’s a good thing that didn’t spill during Irma. The Alapaha River at Statenville peaked Tuesday and probably would be a fine ride (what shoals?) today. The New and The Santa Fe Rivers are still flooding, and that’s still raising the Suwannee River all the way to the Gulf, and there’s minor flooding all the way up at Fargo, so another surge of high levels may follow on the Suwannee. The I-75 Santa Fe River bridge never did close.
Update 2017-09-15: On the seventh day.
Hurricane Irma flooded the Suwannee River at White Springs, the Santa Fe River especially at Fort White, with a new record for the New River new Lake Butler. It did not flood the Withlacoochee or Alapaha Rivers.

Update 2017-09-15: On the seventh day.
Hurricane Irma is bringing flood levels on on most of the rivers in the Suwannee River Basin. Here are the gages with projections from downstream to upstream, since Irma is coming from the south. The images here are static to show this moment, but click on any image to go through to the live gage.

Salt water intrusion inland is worse than you think, including the “Apalachicola salinity feature” up to the GA-FL line and east through Lowndes County, with a special additional brackish Valdosta feature. Central north Florida is an island of fresh groundwater surrounded by entire saline Florida coast around from Alabama plus across to Brunswick, GA, then again from Savannah up past Charleston. South of Lakeland, FL the map is all red for saline.
Apparently using the data preliminarily mapped earlier in the Florida Well Salinity Study, geologists from three states connected the dots in Revised Hydrogeologic Framework of the Floridan Aquifer System in Florida and Parts of Georgia, Alabama, and South Carolina, By Continue reading
The crowd was very attentive to every word about wastewater and flood prevention, with officials from the City of Valdosta presenting in the first of a new quarterly WWALS speaker series. If you didn’t come, you can see and hear in these videos Henry Hicks about wastewater, Emily Davenport about flood prevention, Tim Carroll about solar power, and Sementha Mathews about how to get more information from Valdosta. WWALS Treasurer and acting Executive Director Gretchen Quarterman opened and closed the meeting.
Each talk had many small but important stories, so we will probably blog more posts about those. Meanwhile, here are the videos: see for yourself! Continue reading

Come hear about the $60 million in wastewater fixes Valdosta just finished, what remains to be done, and what they’re doing about flood prevention for the entire Suwannee River Basin in Georgia and Florida. You can ask questions in this first of a new WWALS Quarterly Speaker Series, and the people organizing this work will be there to answer:
- Henry Hicks, Utilities Director, about wastewater
- Emily Davenport, Assistant Director of Engineering, about flooding, and
- Tim Carroll, Valdosta City Council, about solar power for utilities.

Valdosta already had an airplane fly over Lowndes County and collect Light Detection and Ranging (LiDAR) data for flood mapping. Will Lowndes County step up and match Valdosta on this project that affects everybody in the county (and downstream into Florida)? Valdosta started this LiDAR project in March 2015, and Valdosta fronted the entire cost to get it done, we know because Valdosta Assistant Director of Utilities Emily Davenport and Valdosta City Council Tim Carroll told us at a meeting Valdosta held at the request of WWALS for interested parties downstream in Florida and from as far away as Atlanta.
On the agenda for the 8:30 AM Monday morning Lowndes County Commission Work Session, item 7.d. Continue reading
