Model Form:

Funding to maintain the continuous water-quality monitor at this site ended on September 30, 2005.

Model Form #1

NO3 = - 1.73 + 0.797 log₁₀(Q) - 0.298 log₁₀(TEMP)

where:

NO3 is computed diss. nitrate, in milligrams per liter as nitrogen
Q is computed discharge, stage-discharge rating curve, in cubic feet per second
TEMP is water temperature, in degrees Celsius

Model Calibration
