Ramp Radar shows you every public boat ramp and water access point in South Georgia, color-coded by the current USGS river level. Before you hitch up the trailer, one tap tells you whether launch conditions are good, risky, or closed. No guesswork, no wasted trips.
River levels change fast. A ramp can go from perfect to flooded or too-shallow in hours. Ramp Radar stays in sync with USGS monitoring stations so you see conditions as they are right now. Whether you're fishing, launching a kayak, or taking out the jet ski, you'll know the real status before you arrive.
Open the map and browse all ramps in your area. Green markers mean safe to launch. Yellow means marginal—water is high or low, and you should check the detailed reading before committing. Red means the ramp is not usable under current conditions. Tap any ramp to see the exact USGS gauge reading, recent trend, and whether conditions are rising or falling. The map works on desktop and phone, so you can check conditions from home or on the road.
USGS (waterservices.usgs.gov) provides real-time river measurements from gauging stations across South Georgia. Ramp Radar uses these readings to determine whether each ramp's water level is in the safe zone. Ramp locations come from OpenStreetMap and verified local access information, so you always know where you're going.
How often does the color change?
USGS updates readings every 15 to 60 minutes depending on the river. Ramp Radar refreshes the status whenever new data arrives, so the colors stay current throughout the day.
What if the ramp is marked red but I know people are launching?
Ramp status is based on a safe water-level range for launching and retrieving. If the river is running high or low outside that range, the status turns red as a safety warning. Always use your judgment and the USGS reading provided.
Can I see rivers outside South Georgia?
Ramp Radar focuses on South Georgia's main fishing and recreation areas. For rivers elsewhere, check USGS directly at waterdata.usgs.gov or contact the local state park or recreation area.
