Station: Station A Eldridge

Station Name: 
Station A Eldridge
Station ID: 
STA
Collected Data Types: 
Stream Flow
Collected Data Types: 
Stream Sediment Monitoring
Collected Data Types: 
Stream Temperature

Sonoma Ecology Center's automated data collection station at Station A (STA) measures stream depth, stream temperature, stream turbidity, and rainfall.

The station, installed by SECSonoma Ecology Center is a not-for-profit organization located in the Sonoma Valley. http://sonomaecologycenter.org with the assistance of EME Systems of Berkeley, California, uses ab OBS-3 turbidity probe, a separate water temperature and depth sensor, and an OWL2c datalogger to take measurements of the listed parameters. Readings are made at 15-minute intervals to coordinate with the stream flow reading from the U.S.G.S. guage at Aqua Caliente bridge site (station SCG, River Station 9.0+530).

Stream Flow at Station A

Water depth data has been collected Sonoma Ecology Center at Station A for various periods. This could be converted to stream flow if needed for future analysis.

At this time the raw data has been quality controlled but not processed. All parameters collected (stream temperature, depth, turbidity, and weather data) are archived together. See this record for accessing Station A Raw Data: http://knowledge.sonomacreek.net/StationARawData.

Stream Sediment and Turbidity Data at Station A

Pictured above is a graph plotted from data from samples taken at Station A in hydrologic years '02-'04, calculating the relationship between turbidity-meter reading (NTUs) and suspended sediment in mg/l from dried and weighed samples. This relationship allows us to continue monitoring of sediment using the less labor-intensive turbidity method. Since that graph was published we have collected more of both types of samples and plan to add them into the relationship equation to increase confidence in it.
