Chapter 8: Impacting Streams and Rivers

back to previous page

Chlorophyll-a

The Pelican River inlets accounts for nearly ¾ of the total ChlA entering the Lake. Total inlet and outlet concentrations of ChlA range from 0.0 to 0.01 ug/L. One sample of total inlet ChlA concentration ranges approximately 0.05 ug/L. This may correspond with an algae bloom. ChlA loading from Bob Creek and Duck Lake is significantly less that from the Pelican River inlet.

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.
