Latest observation

What this gauge represents: This gauge measures conditions on Meramec River at its USGS monitoring location in St. Louis County; conditions elsewhere on the waterway may differ.

How to read these numbers
Streamflow (ft³/s or CFS)

How much water moves past the gauge each second. Higher numbers mean more water is moving downstream.

Gauge height (ft)

The water-surface height at this gauge. It is useful for tracking rises, falls and flood thresholds, but it is not the river's total depth.

24-hour change

How much the latest reading has risen or fallen compared with roughly 24 hours earlier.

Historical median

The typical streamflow for this date based on USGS historical statistics. A multiple such as 3× means current flow is about three times the historical median.

NOAA flood stage

Official action and flood thresholds where available. These levels are specific to each gauge location.

Gauge height and flood stage are station-specific. A 12-foot reading at one gauge should not be directly compared with 12 feet at another.
