About this gauge

USGS gauge 02485735 sits on the Pearl River and reads everything draining 3,130 square miles of the Middle Pearl-Strong basin. Its datum sits 233 feet above sea level NAVD88. Daily flow has been on record here since 2020, 6 years of it.

Where this gauge sits in the drainage

Pearl River at Ross Barnett Reservoir, MS sits immediately upstream, so dam releases rather than rainfall set the flow here. One gauged site sits upstream of here. The closest is Pearl River at Ross Barnett Reservoir, MS, reading 3,050 square miles. This gauge adds the 80 square miles that drain in between. Downstream the next reading comes from Pearl River at Jackson, MS at 3,171 square miles, so what passes this gauge is about 99% of the water measured there.
