Local Lawmakers Reestablish Lake Lanier Caucus to Address Water Taste, Odor

State Rep. Matt Dubnik and Sen. Drew Echols moved this week to reestablish the Lake Lanier Legislative Caucus in response to recent complaints of musty, earthy and foul-tasting water drawn from Lake Lanier and the Chattahoochee River, lawmakers said. The caucus, which Dubnik led previously, aims to bring state, federal and local partners together to investigate causes and solutions.

"Collective action is needed to examine the causes and effects of the recent taste and odor issues that impact millions of users of water from Lake Lanier," Dubnik said; he is chairman of the House Appropriations Subcommittee on Education and identified himself as the caucus’s returning chair. The formal Lake Lanier Legislative Caucus will convene members who represent areas around the lake and work with municipal partners such as the City of Gainesville and advocacy groups including the Lake Lanier Association.

Sen. Drew Echols, a Gainesville Republican and caucus co-leader, said constituent contact has surged. "Our emails and phones have been blowing up just about the taste of the water in Lake Lanier and the city of Gainesville in particular for my district," Echols said, framing the reconstitution as a direct response to community complaints from Hall County, north Fulton County and Forsyth County representatives. Echols added the caucus intends to "bring in Congressman McCormick. We've got to bring in Congressman Clyde, as well as the Corps, EPA, and EPD."

The Senate press release accompanying the announcement identified two compounds as primary culprits: geosmin and 2-methylisoborneol (MIB). Those naturally occurring organic compounds, produced by microorganisms such as algae and bacteria, are responsible for imparting a musty, earthy taste and odor to water, the statement said.

Local authorities and water experts have told elected officials that, despite the off taste and smell, the water is considered safe to drink. Public works officials in north Fulton County attributed similar changes in smell and taste last October to annual turnover in the Lake Lanier–Chattahoochee River System. At the same time, state-level water planning efforts are already underway: a three-year federally funded study by the Georgia Water Planning and Policy Institute is in progress, and a $2.5 million federal grant directed to the Georgia Water Planning and Policy Center is slated to fund upstream work with farmers to reduce sediment and nutrient runoff.

Caucus leaders said their work will span immediate taste-and-odor responses and longer-term policy: examining water quality and safety, lake levels and economic impacts, pollution reduction, boating safety and debris removal, ensuring long-term water supply for growing North Georgia communities, and protecting recreational access. Public hearings and coordination with federal partners were specifically mentioned as planned next steps.

With Lake Lanier central to tourism and local economies, Dubnik and Echols framed the caucus as a means to restore confidence and craft legislative and operational fixes. The group’s first meetings and membership roster are expected to provide the next concrete steps as lawmakers press utilities and agencies for test results, treatment plans and timelines to resolve odor and taste concerns.
