Flood Inundation Mapper (FIM) 2019-10-21

Valdosta and Lowndes County spent some money for LiDAR to map flooding extents at various Withlacoochee River water levels. The result is in the USGS Flood Inundation Mapper.

The map starts just below the Skipper Bridge Gauge on the new Skipper Bridge, down to the GA 133 Withlacoochee River Bridge. Too bad they didn’t go about a thousand river feet farther down to the Little River Confluence.

Here are some screenshots at various levels.

VSU Geology and ASA at Land Between the Rivers 2019-11-26

Two Geology Professors visited The Land Between the Rivers and wrote a letter about many projects they and their students can do there, at the site of Troupville Boat Ramp. This is more in-kind match for the GOSP grant pre-application.

Videos, Valdosta Wastewater and Flood Prevention 2016-10-27

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

Road Closures in 2009 Flood, Lowndes County, GA

Back in 2009, Lowndes County spent hundreds of times more in infrastructure repairs than the $40,000 that Valdosta is asking as a match to build an online flood warning map, beyond just fixing sewer system spills to dealing with the rest of the flooding problem. Map of roads closed At recent meetings, some County Commissioners seemed reluctant to authorize the request because the proposed map mostly covers subdivisions in Valdosta. But the entire county was affected by road closures in 2009, so maybe Commissioners could ask to expand the map to cover the whole county, which could also help find sources of the flooding problem. Sources and effects extend all the way to the edges of the county, as you can see in this a google map I built back then:

Roads closed in Lowndes County, Georgia, as of 9:38 a.m April 6th, according to the Valdosta Daily Times. This map shows locations and terrain. It’s a Google map, so it’s interactive: you can zoom and pan and change to satellite view, street map, street view, etc. Some of the locations are guesstimates from the cryptic descriptions in the VDT article. The one green blob is the one reopening mentioned in the article: “North Valdosta Road Withlacoochee River Bridge opened at 10 p.m. Sunday.”

That VDT article no longer seems to be online, but this one is. Jason Schaefer, VDT, 27 April 2013, What natural events cost Lowndes taxpayers, Continue reading

Lowndes County to match Valdosta funding for LiDAR flood mapping? 2016-07-11

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

Geological determinations about Sabal Trail and Suwannee River by Dennis Price P.G.

Sinkholes, springs, and caves abound where Spectra Energy wants to gouge its yard-wide Sabal Trail pipeline Figure 1. Location Map of Sabal Trail Pipeline through the heart of the Florida Springs Heartland, wrote a Practicing Geologist WWALS member to FERC, following up on his testimony in WWALS v Sabal Trail & FDEP.

Here is the text of the report by Dennis Price, followed by the images (PDF in FERC accession number 20151027-5034), all about the same area where WWALS board member Chris Mericle recently guided Hamilton and Suwannee County Commissioners to see for themselves. -jsq

Video: WWALS outings on Chris Beckham drive-time radio WVGA 105.9 FM 7:30 AM 2016-01-15

Here’s WWALS video of the radio interview this morning on WVGA 105.9 FM. It’s an invitation to tomorrow morning’s events, both at 10AM:

Chris also got me to say a few words about why WWALS formed in the first place, and why you should all join WWALS; it has to do with the 700-year flood in 2009.

Plus some plugs for Valdosta’s wastewater fixes and their recent LiDAR flight.

The one thing I realized on the way out I forgot to mention, the one item that caused me to schedule this interview, was the workshop at VSU February 27th about the Withlacoochee and Little River Water Trail, featuring the visual beauty of all WWALS’ rivers in an art exhibit and silent auction, the geology on display by Dennis Price, and the remains of past people and cultures still visible along the river by Tom Baird.

Looking forward to seeing you tomorrow morning on the Little River, or other WWALS members look forward to seeing you tomorrow morning on the Suwannee River. If not tomorrow, there’s plenty more to do on our beautiful south Georgia and north Florida blackwater rivers!

Here’s the video:

FERC, EPA rubberstamp Sabal Trail fracked methane pipeline: opposition continues –VDT

The FERC FEIS isn’t a permit, the Army Corps hasn’t issued a permit, GA-EPD is still considering an air quality permit for the Albany, GA air compressor, and it’s still possible to stop the GA-DNR easements for drilling under Georgia rivers including the Withlacoochee and Okapilco Creek. This is all regardless of whether FDEP issues its drilling permit for the Suwannee and Santa Fe Rivers. You can still help stop this invasion by the “Sinkhole Trail” of our local lands, water, and air.

Among the press recently by Politico, Law360, Natural Gas Intelligence, the Suwannee Democrat, the Ocala StarBanner, the Palm Beach Post, the Atlanta Journal-Constitution, Valdosta Today, and others, is this long local piece. Joe Adgie, Valdosta Daily Times, 20 December 2015, EPA reverses stand on impact pipeline would have on aquifer,

In addition, according to FERC, Sabal completed analysis of the subsurfaces where the pipeline is proposed.

That’s what FERC’s announcement of its Final Environmental Impact Statment (FEIS) said, but where is the LiDAR, as Continue reading

Who, beside the public,is checking the data Sabal Trail is providing? –Chris Mericle to FERC

WWALS board member Chris Mericle just asked FERC:

Why the huge discrepancy….? [W]hy should we believe that the information Sabal Trail provided anywhere is correct?

Chris pointing to tree that fell in sinkhole 30.4080314, -83.1609955 Apparently unlike FERC, Chris knows what he’s talking about, from on-the-ground observation to a local study by a geologist, to Sabal Trail’s own docuemnts.
