Swift Creek @ Suwannee River Water Quality Testing 2025-06-21

We had heard a report from Wednesday of a fish kill on Swift Creek, apparently at the Suwannee River.

So yesterday three of us went there and tested the water. We didn’t see any dead fish, and the Swift Creek Confluence doesn’t look much like what was in the Wednesday report video, so we’re not sure where that was.

We tested for E. coli, which was pretty clean, pH, which was slightly towards the base end, and Dissolved Oxygen (DO), which was low, but not fish-killing low. Probably it’s worth testing again.

Swift Creek comes down from the huge phosphate mine north of White Springs, which has previously gotten the mine’s owner into trouble with the U.S. Environmental Protection Agency (EPA).

A clean river is what we like to see, and the most recent bacterial tests show the Withlacoochee River clean. You can help us keep determining when it is clean.
