Land Use (L) and
Lake Concentration (P)
Phosphorus Loading

�L = W / As

�P = L / (11.6 + 1.2qs)


	The amount of phosphorus entering LPN W term was further manipulated to assign loading due to land-use effects independently from other sources.
	L is annual phosphorus areal loading in kg/m2/yr. This value comes from dividing the best estimate phosphorus loading W�s by the lake surface area (A sub s).
	P is the predicted phosphorus concentration in LPN. The areal loading is divided by the term 11.6 +1.2qs, which corresponds to the settling velocity of phosphorus and areal water loading in the lake.
