Graph Legend: Secchi symbols = average Secchi Disk Transparency Values; tick marks = maximum and minimum values for each year.

**Table Legend:**

**Color**: Color (SPU), **Alk**: Alkalinity (mg/l CaCO₃), **SpCon**: Specific Conductivity (\(\mu\)S/cm), pH: pH (standard units)

TP = Total Phosphorus (\(\mu\)g/L) – EC: Epilimnion Core, SG: Surface Grab, BG: Bottom Grab, PG: Profile Grab

**SDT** = Secchi Disk Transparency (m) – **Min**: minimum value, **Avg**: average value, **Max**: maximum value, n: number of months with Secchi readings per year, b: number of times Secchi disk was observed touching the bottom of the lake per year
**Chl** = Chlorophyll-a (\(\mu\)g/L) – **Min**: minimum value, **Avg**: average value, **Max**: maximum value
