Waderly combines real-time USGS stream gauges with weather, barometric pressure trends, and solunar activity so you know what the water is doing before you go. The "typical" comparison above is an approximation based on the historical daily median flow for this date at this gauge.
These nearby gauges are on the same named waterway, which makes them more useful for upstream and downstream context than unrelated creeks at the same distance.
Other gauges on St Marys River worth checking include ST MARYS RIVER AT FERRY LANDING NEAR FOLKSTON, GA (28.5 miles away). Same-waterway gauges are usually the best upstream and downstream cross-check when you are deciding whether conditions are improving or dropping out.
