Hurricane Idalia heading for Suwannee River Basin 2023-08-29

Update 2023-08-29: Georgia declares State of Emergency for Hurricane Idalia 2023-08-29.

Hurricane Idalia is now Category 1 and is headed a bit farther west, taking it straight up the Suwannee River Basin.

Cat 1 means sustained winds of at least 74 mph, up to 95 mph. Inland it will probably rapidly degrade to a Tropical Storm. That still means 39-73 mph winds.

Before landfall, Hurricane Idalia may strengthen to cat 2 (96-110 mph with extensive damage) or cat 3 (111-129 mph with devastating damage).

I’m going out and securing anything that might turn into a projectile, even though I’m about a hundred miles from the Gulf Coast.

For those who are tired of being warned: this is a hurricane. It’s much better to be prepared than sorry.

I drove up from Gainesville yesterday, and there were already rain gusts strong enough to buffet my car and to cause everyone on I-75 to slow to 45 MPH. When the wind gets up to 50 MPH, you don’t want to be driving, even if you don’t run into flooding or bridges out. At 74 MPH, you want to be inside something solid. Continue reading →

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.

Hurricane Dorian expected this weekend 2019-08-31

Update 2019-08-29: All Amtrak trains and Greyhound buses from Virginia to coastal Georgia cancelled for Sunday and Saturday, and flights even if not canceled are absurdly expensive at this late date, so I’m not leaving for Virginia today; I’ll be staying here for the duration. And these cancellations indicate Amtrak and Greyhound at least are considering Dorian something to worry about.

Hurricane Dorian is expected to be category 4 (130-156 mph winds) when it lands Monday somewhere on the east coast of Florida, and we could see tropical storm winds (39-73 mph) in Cedar Key Saturday and in Valdosta Sunday.

Videos: Parker Pond water withdrawals, BMAPs, Valdosta, and Testing @ SRWMD 2019-05-14

The deputy went in to see what the ruckus was about. It was Lu Merritt, Mike Roth, Jim Tatum, Mike Kern, and then me, in extensive discussion about a water withdrawal permit request, that Jim Tatum called Words of Truth to the Suwannee River Water Management District (SRWMD) Board.

On the agenda for that Monday, 14 May 2019:

20. Approval of New Water Use Permit 2-001-234425-1, Authorizing a Maximum 0.1462 mgd of Groundwater for Agricultural Use at the Parker Pond Project, Alachua County

I was actually there for this later item:

30. Valdosta Wastewater Update

In interaction with Tom Mirti, I confirmed that FDEP is doing DNA and sucralose (human waste marker) testing monthly at the GA-FL line on the Withlacoochee and Alapaha (not Alapahoochee) Rivers, and at the Withlacoochee Confluence with the Suwannee River. However, SRWMD has no plans for doing complementary weeks.

I found the public relations method research by Katelyn Potter to be fascinating.

Bradford BOCC 2018-09-04

All the public speakers were against the phosphate mine. Before the Commissioners decided, Merrillee Malwitz-Jipson spoke about rain, the Chemours mine, and how what Bradford County does affects her business downstream. (I think Stasia Rudolph also spoke before I got there.) After some confusion on timing, afterwards Marc Lyons reminded them Citizens Against Phosphate Mines (CAPM) is ready to sue, and Kate Ellison said she hopes this means we will all see the consultant’s report before the public hearings. I sent a letter and a resolution the previous day and gave them paper copies.

The actual decision was much better than expected. While some Commissioners wanted to hold Continue reading →

Gornto Road, Valdosta, access to Withlacoochee River 2018-01-24

It could use some markers to keep people on it and off private property, and maybe some loaner kayak wheels, but there is public access to the Withlacoochee River off of Gornto Road in Valdosta.

Videos: Surprise phosphate mining discussion at Bradford County, FL BOCC 2017-07-20

The regular attendees said there would be no fireworks this time. Yet it was a very interesting meeting, especially once the County Attorney asked for scheduling a date to select the consulting engineer about the phosphate mine. The Commissioners and staff discussed August 8 in the morning or August 17 in the evening. Public comment preferred the latter. The County Attorney strongly advised they go ahead and decide when so there will be plenty of time to advertise it. The decision: Thursday evening, August 17, 2017.

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 →
