Water Quality

The following report was commissioned to determine what aquatic plants, algae, and plant nutrients were present or changing in Fairview Lake,  Fairview, Oregon.  Researchers from Portland State University collected samples during the summer of 2008.  This report presents those data and interprets their meaning in a highly readable and understandable fashion.

The depth of Fairview Lake varies during the summer from 4.5 to 5.5 feet pretty much from shore to shore.  In clear lakes, sunlight has no problem reaching the bottom and encourages the growth of rooted aquatic plants down to 20 feet or so.  Fairview Lake, however, is usually very turbid due to high winds and the presence of common carp that disturb the soft silty bottom.  The turbidity limits sunlight and thus limits the growth of plants.  If aquatic plants were to become established, it is likely they would grow from shore to shore.

Algae grows very well throughout the lake during certain periods of the summer.  The researchers determined what types of algea and what levels of nutrients (chemicals) were present.

This is an excellent report and I hope that you will find it interesting and informative.
