Live water quality data from the Lake

Deploying the buoy
Dial-up Broadband QuickTime™

The display may take a minute or longer to appear. Please be patient.
See the limitations on the use of this data (below).


   

   

 
 

 

 

 

 

 

 
Note: During extended periods of hypoxia in the lower water layer of Onondaga Lake (when dissolved oxygen is < 2.0 mg/L), the dissolved oxygen probes at 12 meters and 15 meters are removed from the water quality instruments to prevent damage.

  The "NaN" (that is, "Not a Number") displayed in the dissolved oxygen dial indicates that the measured dissolved oxygen value is not available because the probe has been removed.

Disclaimer

Data obtained from Onondaga County's telemonitoring buoy is transmitted on 15 minute intervals to a receiving station at the Metropolitan Syracuse Wastewater Treatment Plant by radio frequency transmissions. The data is received and automatically processed for anomalous values through a software program before it is transmitted to the web site for viewing by the public.
 
Anomalous or incorrect data may still be transmitted, caused by mechanical problems or invalid readings from occurrences such as instrument fouling by biological materials, instrument malfunction due to flotsam and/or jetsam, unusually high battery drain, failure of solar energy panels and/or radio frequency noise transmitted with the data signal.
 
The data from the buoy (above) has not been reviewed or validated by WEP staff and, therefore, is considered to be provisional. WEP is not responsible, nor does it assume any liability, for any damages caused by inaccuracies in this data or documentation or as a result of the failure of the software to function in a particular manner.
 
WEP makes no warranty, expressed or implied, as to the accuracy, completeness, or utility of this information, nor does the fact of distribution constitute a warranty. Final data will be published yearly in the Onondaga Lake Monitoring Program's Annual Report when issued by WEP.
