Are the rivers rising? 2024-10-01

Somebody asked: has the Suwannee River crested after Hurricane Helene? Yes, upstream from the Alapaha River (Nobles Ferry Gauge) and downstream from the Santa Fe River (Rock Bluff Gauge). In between (Nobles Ferry to Branford Gauge) it’s still rising, although nowhere near Action Stage.

The Santa Fe and New Rivers were mostly unaffected by the storm.

The Little, Withlacoochee, and Alapaha Rivers are or were all in flood upstream, rapidly heading downstream.

So if you must go boating, the Santa Fe River or the Middle Suwannee River are your best bets. But if you can, stay off the roads and let emergency vehicles, road crews, and utilities work.

Details below, taken from the NOAA National Water Prediction Service. NOAA is the first option in River water levels in the Suwannee River Basin 2024-08-07.

The most extreme Suwannee River water level rise was into Major Flood during the storm, at the Above Gopher River Confluence Gauge, which got both rainfall and storm surge.

There was risk of flooding way up the Suwannee River past Branford, but that has receded now.

The purple-colored rivers and streams on the NOAA map are high, matching the stretches with gauges with high or rising water levels.

The Little River has peaked, but is still in Minor Flood near Adel and on GA 122 near Hahira (Folsom Bridge), now dropping fast.

The Santa Fe River at Three Rivers Estates is in Action Stage and predicted to keep rising for a week. The Santa Fe River at Worthington Springs is rising, almost into Action Stage. The other Santa Fe River gauges were mostly unaffected by the storm.
