If the delay between seeing a lightning flash and hearing thunder is 30 seconds or less, the thunderstorm cell is within 6 miles — seek shelter immediately. Always wait a full 30 minutes after the last clap of thunder before returning to open water.

Quabbin Reservoir is located in Massachusetts at coordinates 42.3592° N, 72.3000° W. These coordinates represent the hydrographic center point verified against the USGS Geographic Names Information System (GNIS) and National Hydrography Dataset (NHD).
Our real-time lightning radar monitors electromagnetic atmospheric discharges within a 30-mile radius of Quabbin Reservoir. Concentric safety rings indicate proximity: 5 miles (critical danger zone), 10 miles (15-minute arrival warning), 20 miles (basin caution), and 30 miles (perimeter monitoring). It tracks storm bearing, flash density, and evaluates the marine 30-30 safety rule.
The live radar overlay displays a real-time 6-frame precipitation loop powered by RainViewer and NOAA NEXRAD Doppler radar composites. It updates every 10 minutes to show incoming storms, rain, snow, and thunderstorm cells directly above Quabbin Reservoir. You can pause, play, or scrub the timeline using the controls in the top-right corner of the map.
Quabbin Reservoir features multiple shoreline access points. Launch sites typically provide concrete ramps, docks, and parking, though seasonal water levels and park permits may affect launch availability.
