Chapter 8: Impacting Streams and Rivers

back to previous page

Ortho Phosphorus

The Pelican River accounts for over half of the total OP entering Pelican Lake . Generally the concentration of OP coming into the Lake mimics that exiting. The OP concentrations seem to correspond at the inlets, with from Spring Creek. Given one site, the OP concentrations of the other inlets sites are not usually radically far off. The total OP entering and exiting the lake is approximately the same. This means that eutrophication is limited and in equilibrium. OP Loading from Bob Creek and Duck Lake is much less than Spring Creek and the Pelican River .

Notice the difference between the concetration and the loading. Loading is a better estimate of what is impacting the stream and lake because it combines both concentration and the volume of water (flow). Loading is calculated in lbs/day, while concentration is calculated in mg/L.
