2. At dam: TP = 5 + 740/[dam height (ft)] Upper lake segment
Prediction equation as applied to upper lake segments in Ozark Highlands
At dam: TP = /[dam height (ft)]
Upper lake segment
Depth coefficient (z) = [dam height]/[lake depth at dam]
TP = /[z*(depth at sample site)]
Reference Criteria: 26 ug/L
