Temperature
& Oxygen Profiles

Temperature & Dissolved Oxygen Profiles

Most recent late summer (Aug. 1 - Sept. 7) temperature and dissolved oxygen profile plots

 



Temperature and Dissolved Oxygen profile Contour Plots
Displayed only for lakes with profile data collected in at least 5 months from May - Oct.
 

 

Temperature and Dissolved Oxygen Profile Data

Late summer only (Aug. 1 - Sept. 7); limited to eight most recent profiles

Units: Temperature (TEMP) = °C; Dissolved Oxygen (DO) = mg/L

Trophic and Water Chemistry Data

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
