Global Croplands, Suwannee River Basin

You can see on these maps that the Suwannee River Basin is massively agricultural, except where it’s forestry or swamp or other wetlands. Thus it’s no wonder that most of the nitrate runoff problem here is due to agriculture, as shown in the Basin Management Action Plans (BMAPs).

Basin Wide, Maps

WWALS Science Committee Chair Tom Potter points to this Global Croplands map to illustrate the BMAP issues. The question remains of whether agricultural best management practices as advocated in the recent BMAP meetings will be sufficient to deal with the problem, considering they haven’t decreased it in the past decade.

Suwannee River Basin Maps

Update 2019-02-13: And a version with Landings. See also Water Trails, with more detailed maps and access points.

Nobody seems to have done this, so we did: a map of the Suwannee River Basin, with the major watersheds and the Estuary shaded, and all the major rivers, plus many of the creeks. Bonus: springs! Narrow, Suwannee River Basin Click on this link for an interactive google map of the Suwannee River Basin.

The river traces come from USGS and Chris Graham. The watershed boundaries are from USGS. The springs are from the Florida Springs Institute, plus four Georgia springs collected by WWALS.

The eight-digit hydrologic unit codes (HUC8) for the Suwannee River Basin are: Continue reading →

Lead TMDL Evaluation for Three Segments in the Suwannee River Basin 2016-06-01

Rivers Seven Days After Irma 2017-09-17

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.

Where nobody lives in the Suwannee River Basin

Obviously nobody lives in most of the Okefenokee Swamp or the Osceola National Forest, but also most of Clinch County is unpopulated west of the Swamp, as is much of the Gulf coast along the Suwannee River Estuary, from Cedar Key north to Horsehoe Bay, plus large parts of Dixie and Lafayette Counties west of the Suwannee River.

Update 2017-06-20: As someone pointed out, rangers do live in the Okefenokee Swamp, presumably in the white area along the access road.

Cedar Key is the island at the bottom of the map, and from a bit north on the Gulf Coast you can follow Continue reading →

Suwannee River: standard for dissolved organic matter

A primary objective of the WWALS Science Committee is to compile published scientific literature for the Suwannee basin. We are doing this using online search engines including the University of Georgia System Galileo program and Google Scholar. Remarkably, our searches have identified thousands of published scientific papers and reports that link to the keyword, “Suwannee”. Examination of many revealed that they describe research using dissolved organic matter isolated from the Suwannee River near Fargo, GA. This is the material that gives the water its special color.

Delineation of Spring Protection Areas

These figures tell the story of springsheds in a coastal lowland karst plain such as much of the Suwannee River Basin. Maybe you already know all this, but if you don’t, these pictures may help make sense of Springsheds and Water Withdrawal Permits in the Suwannee River Basin.

Videos: Coal Ash meeting in Valdosta @ WWALS 2017-03-01

The Georgia legislature did nothing but appoint a study committee, but you can see why they should do more, in these WWALS videos of the coal ash meeting in Valdosta that was organized by Rev. Deacon Leeann Culbreath of Georgia Interfaith Power & Light (GIPL). Thanks to Rev. Floyd Rose for the venue at Academy of Excellence on Lee Street.

The Valdosta Daily Times covered this meeting, but did not mention the local landfill, which was a major topic of my presentation, as you can see in my slides. The Mayor of Valdosta disclaims any control over that landfill and the Lowndes County Commission expressed no interest. Nevermind both city and county governments have Continue reading →

Only Valdosta and Tifton spilled sewage in Georgia in Suwannee River Basin in January 2017

GA-EPD’s Atlanta office sent their entire sewage spill database for January 2017 in response to an open records request from WWALS. For the Suwannee River Basin, I see only the known ones by Valdosta, plus a spill from Moultrie’s Carlton Woods Lift Station into the Ocholockonee River, with 36000 gallons, which matches the amount we got directly from Moultrie. That Ochlockonee spill is still not in the Suwannee River Basin.

The Georgia Environmental Protection Division (GA-EPD) Southwest office in Albany handles the other sewage treatment operations in the Suwannee River Basin in Georgia, and that Albany office already told us by telephone that they had no reported spills other than the Tifton spill into the New River which I had gotten directly from Tifton. So I think we can conclude there were no other sewage spills into the Suwannee River Basin in Georgia in January 2017 other than the ones from Valdosta and Tifton.

Interestingly, Valdosta with its 2.2 million gallon Withlacoochee Wastewater Treatment Plant (WWTP) leak (and three manhole spills) was not the winner. Continue reading →

SRWMD responds about NFRWSP; come to Alachua Tuesday 2017-01-17

SRWMD did post responses to comments from WWALS and others on the North Florida Regional Water Supply Plan (NFRWSP). A week before the planned NFRWSP adoption, same as for the agenda for the joint SRWMD-SJRWMD meeting next Tuesday in Alachua. After OSFR and WWALS posted critical blog posts, SRWMD Executive Director Noah Valenstein sent us and others an offer to meet this Friday in Live Oak to discuss. While many (including me), thanked him for his collegial offer, nobody took him up on it. See you in Alachua Tuesday (facebook event).

Below are Noah Valenstein’s letter and my response. Continue reading →
