Secchi Disk Transparency is a water clarity measurement and has displayed a slight trend of decreasing water clarity since 1984. On a positive note, the Secchi Disk transparency was relatively stable between 2014 and 2017 before varying widely the past two years.

Chlorophyll ɑ concentrations, a measure of microscopic plant life within the lake, display a trend of increasing concentrations since 1984. On a positive note, the chlorophyll ɑ concentrations have stabilized since 2010 with lower seasonal average values documented over the past two seasons. From this graph and the previous Secchi Disk Transparency graph, you can see the relationship between plant growth and water clarity; when plant growth goes up, water clarity goes down (2007 and 2009 are good examples).

Phosphorus is the nutrient most responsible for microscopic plant growth. The total phosphorus concentrations have oscillated over the years while the long‐term trend suggest a slight reduction (improvement) in total phosphorus concentrations Phosphorus data is often correlated with the amount of plant growth; increased phosphorous contributes to increased plant growth.
Water Color

Lake water color is a result of naturally occurring “tea” color substances from the breakdown of soils and plant materials. Color has varied annually and displays a relatively stable trend from 1985 to 2019.
