Methods: 

Dissolved oxygen and water temperature were measured using a HOBO datalogger secured inside a perforated PVC pipe attached to the south dam abutment.

Dissolved oxygen percent saturation was calculated using HOBOware software and barometric pressure data from Marshview Farm.

NOTES AND COMMENTS: HOBO dissolved oxygen loggers have a sensor cap that requires replacement every 7 months. If the logger is deployed when the sensor cap expires, no usable data is collected after that point.

FLAGS:
1 -- datalogger not deployed
2 -- datalogger malfunction
3 -- datalogger sensor cap expired

Maintenance: 

Measurements completed for year.
