Symbols show calibrated K & C1 (+- 1 Standard Error) with C0 = 4 ppb (STA's & Reservoirs), C2 = 200 ppb (STA's), C2 = 0 ppb (Reservoirs)

Higher values of C1 reflect indicate less phosphorus storage in biomass and more rapid response to pulse inflow loads.

Higher values of K indicate higher average removal rates at a given water column concentration.

Rodman Reserv. clusters with STA's, but is not representative of CERP designs because of high hydraulic load and length/width ratio.

Enhanced STA cells are managed to promote submersed vegetation or out-perform standard emergent cells for unknown reasons.

STA calibrations are preliminary.
