With no rain to wash contamination in, the Withlacoochee and Santa Fe Rivers still look clean in the test results we have.

No new sewage spills have been reported this week in the Suwannee River Basin in Florida or Georgia.

As always, we can only advise with the results we have. Happy paddling, swimming, fishing, and boating this weekend.

The numbers in the chart boxes indicate E. coli levels as colony-forming units per 100 mililiters (cfu/100 mL), according to Georgia Adopt-A-Stream bacterial monitoring protocols:
Zero (0) is what we want to see and often we do on the Alapaha and upstream on the Suwannee Rivers.
From 1-125 is within long-term average limits according to U.S. EPA and Georgia and Florida state agencies.
From 126-409 long-term is not good, and is likely to make some people sick.
From 410-999 is likely to make some people sick; try not to get that water on you.
From 1,000 and up: high alert; best not to get close to that water without gloves; wash clothes afterward.

The letters before the numbers indicate the source of the datapoint, as in W100 means 100 cfu/100 mL found by a WWALS tester.
