In addition to "Standard" and "Custom" plots, HEC-EFM Plotter can also be used to investigate concepts like services provided (ecovalues) and seasonality (dates).


"Ecovalues" are measures of how flow regimes performed for each relationship. The figure below displays ecovalues for two flow regimes and shows that the Gaged flow regime (orange) provided generally higher and more consistent ecovalues. Ecovalues offer insights regarding ecosystem services provided and how those services differ between flow regimes.


"Date" is based on the day and month when the statistical parameters of a relationship are met. Dates offer insights regarding when ecosystem dynamics occur and how that seasonality differs between flow regimes. In
the figure below, dynamics associated with big bass winter habitat relationship tend to occur slightly earlier for the Gaged flow regime (green).
