Continuous Record Surface Water Monitoring

Continuous (15 minute interval) monitoring is conducted at nine primary tributary monitoring stations and three reservoir monitoring stations.  These stations are operated and maintained by the USGS and CWD for continuous measurement of stream and reservoir stage, discharge (eight sites only), temperature, and temperature-corrected specific conductance.  Precipitation also is monitored at the three reservoir stations, and wind speed and direction is measured at the Stony Brook reservoir.  Late in 2001, a more elaborate water quality monitoring system was installed at Stony Brook Reservoir which measures turbidity, temperature, specific conductance and chlorophyll-a at three different reservoir depths.

All continuous monitoring information is uploaded on a real-time basis to the USGS internet site, which can be accessed from the link below.
