Water Alert

The U.S. Geological Survey WaterAlert service sends e-mail or text (SMS) messages when certain parameters, as measured by a USGS real-time data-collection station, exceed user-definable thresholds. The development and maintenance of the WaterAlert system is supported by the USGS and its partners, including numerous federal, state, and local agencies.

Water Quality Monitor Network In Ohio

Stream water-quality characteristics provide scientists and water managers with a better understanding of the effects of natural and anthropogenic (human) activities on streams and ecosystems. The USGS operates a network of near-real-time water-quality monitoring stations that provide data for temperature, specific conductance, pH, dissolved oxygen, and turbidity of surface water.
