Summary
instructions
and
information
- Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
- For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
- For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
- For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
- Not all sites have reports available for every water year.

INSTRUMENTATION - Q.W. - A YSI EXO2 Sonde multi-parameter monitor measuring Water Temperature, Specific Conductance, Dissolved Oxygen pH and Turbidity. The Sonde readings are checked against a calibrated field Sonde and compared to stream cross-section values at each site visit. After readings are compared, the monitoring sonde is either cleaned, calibrated, and replaced in the stream, or swapped with a newly calibrated Sonde.
