Suwannee River Basin Maps

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!

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.

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.
