The swimming area of Claystone Park at Lake Tobesofkee reopened Sunday after a water test showed a normal level of the E. coli bacteria.
Macon-Bibb County spokesman Chris Floore said the test showed 57 colony forming units per 100 milliliters of water. The beach is open again effective immediately, he said.
The acceptable level is 190 units. A test Wednesday showed 249 units, then swimming was closed after a follow-up test that came back Friday showed the level at 548 units.
Floore said lake park rangers routinely check for E. coli. The elevated level, he said, may have resulted from rain earlier in the week that washed animal waste into the water.
