Best for the top of the page to explain why these graphs matter.

"In North Georgia, our mountain streams can change in a heartbeat. Whether it’s a summer thunderstorm in the Blue Ridge or a scheduled release on the Chattahoochee or Toccoa Tailwater, knowing the flow is the difference between a productive day and a wasted drive. Use our real-time gauges below to track CFS (Cubic Feet per Second) and water temperatures across our favorite local waters."

Best placed next to or under the graphs to help beginners interpret the data.

• CFS (Cubic Feet per Second): This measures the volume and speed of the water. High CFS usually means swifter currents and stained water—perfect for streamers. Low CFS often requires a stealthier approach and lighter tippet.
• Water Temperature: Trout are most active when water is between 12°C and 18°C (54°F–65°F). If the graph shows temps climbing above 20°C (68°F), it’s time to give the trout a break and head to higher elevations or target warm-water species.
• Gage Height: This tells you the physical depth of the water at the sensor. It’s your best indicator for whether a stream is safe to wade or if you should stick to the banks.

The Chattahoochee River (Tailwater)

"Managing the 'Hooch' requires a close eye on the gauges. Because this is a bottom-release tailwater, water temperatures stay cool year-round, but water levels can fluctuate significantly based on power generation at Buford Dam. Use the graph below to monitor the turbidity (clarity) and discharge rates. For the safest and most productive wading, look for stable low-flow periods, and always keep an eye on the rate of rise if you're fishing the shoals."

The Toccoa River (Tailwater)

"The Toccoa's flow is dictated by the Blue Ridge Dam. Check the CFS graph below before heading out—stable flows are the 'goldilocks' zone for dry fly action, while rising water often triggers a predatory streamer bite."

North Georgia Freestones (Amicalola, Chattooga, Toccoa Headwaters, etc.)

"Unlike tailwaters, our freestone streams rely entirely on rainfall. These graphs help you spot 'the drop'—that sweet spot after a rain when the water begins to clear and the fish start feeding aggressively."

• Spring: Watch for sudden spikes in CFS. Runoff can make wading dangerous, but the edges of the high water often hold the biggest fish.
• Summer: Pay close attention to the temperature graph. In the heat of July, look for the coolest water on the chart to find active fish.
• Winter: Look for "stable and steady" lines. Dramatic drops in temperature can lock down the bite, while a slight warming trend can trigger a mid-day hatch.
