Live river conditions for fishermen
RiverWatch pulls live USGS gauge readings from monitoring stations across South Georgia rivers. You'll see gage height, flow rate, and water temperature updated throughout the day. Use it to pick which river to fish, decide whether to launch a boat, or simply check conditions before you head out.
Every South Georgia river that matters to fishermen is here. The app shows you current conditions at each gauging station, trends over the past few hours, and links to local forecast data. One glance tells you whether the river is fishing or flooding.
Open the map and look for your favorite river. Each station shows current water level and flow. Tap a marker to see detailed readings, recent trend, and whether conditions are suitable for your activity. Higher numbers mean more water; lower numbers mean shallower, slower flow. Your local forecast is linked so you can see if rain is coming.
USGS (waterdata.usgs.gov) maintains real-time gauging stations on major rivers and provides updates every 15 to 60 minutes depending on the station. Weather forecasts come from the National Weather Service (forecast.weather.gov). Water conditions are also cross-referenced with NOAA tide and current data (tidesandcurrents.noaa.gov). Maps use OpenStreetMap so you can see the layout around each access point.
How often does the data update?
USGS stations report every 15 to 60 minutes, depending on the river. RiverWatch refreshes the data on your screen automatically, so you always see the latest readings available.
Why don't I see a specific river?
The app shows rivers with active USGS monitoring stations. Not every creek or small stream has a gauge. If your favorite fishing spot isn't listed, the closest monitored station upstream will give you a good idea of overall conditions.
What do the numbers mean?
Gage height is measured in feet above a reference point; flow rate is cubic feet per second (CFS). Higher CFS means faster, heavier flow. Your app will highlight whether conditions are good for fishing or not suitable for launching boats.
