Monitoring Locations

Monitoring locations were chosen by the City of Santa Rosa, Trout Unlimited, and also by teachers from schools within the watershed as part of the Colgan Creek Restoration Project. These 8 locations will be monitored regularly by students and teachers for pH, water temperature,  air temperature, turbidity,  dissolved oxygen,  conductivity, nitrates, and phosphates . Their data will be uploaded into on-going graphs which can be found at the “Water Quality Test Data” hyperlinks provided with each location below.

TEACHERS: Download the data input form to take out into the field then please Submit Water Quality Data online.

Stream Gauges

stream gauge is an active, continuously functioning measuring device in the field for which a mean daily streamflow is computed or estimated and quality assured for at least 355 days of a water year or a complete set of unit values are computed or estimated and quality assured for at least 355 days of a water year.
