"We ended up getting three bids, which is what we needed," authority chairman Wayne Hawkins said.
As part of an effort to control invasive elodea that has taken hold along much of the channel, the river was lowered three feet on May 16 to allow bidders to inspect the area and offer proposals.
At the time, only two companies sent workers to Augusta, yielding only one bid. Since then, Hawkins said, two other bidders have emerged -- one from Statesboro, Ga., and another from Beaufort, S.C.
"They were close together, and the chemicals they proposed using were all EPA approved," he said.
The authority is scheduled to address the matter at its next meeting, at 9 a.m. June 16 at the Boathouse.
Removing the weeds is expected to improve water flow and aesthetics along the river's downtown portion.
Events held on the river include regattas and the annual Southern Nationals drag boat races.
