Introduction To Tempe Town Lake

Map of Tempe Town Lake

  • Manmade lake
  • Built for flood control and recreational purposes
  • Today, Tempe Town Lake is home to boating, fishing, biking, and more
  • Tempe Town Lake is a good model for understanding larger reservoir systems, such as Lake Powell

Tempe Town Lake

sampling tempe town lake
Sampling Tempe Town Lake
  • Objective: determine seasonal variations in the chemistry of Tempe Town Lake
  • Method: sample Tempe Town Lake twice a week
  • Test the samples for Dissolved Organic Carbons, pH, Dissolved Oxygen, Alkalinity, and Conductivity

Filtration System

Kelly and Hartnett

dissolved organic carbon doc
Dissolved Organic Carbon (DOC)
  • Seasonal variations have been observed
  • DOC levels tend to “spike” during precipitation events

Dissolved Organic Carbon Concentrations

  • Decreases with rain events
  • Evaporation plays a role in conductivity levels
dissolved oxygen
Dissolved Oxygen
  • Varies seasonally
  • Multiple factors appear to be involved
  • Tends to remain fairly constant
  • Appears to be strongly influenced by temperature
  • Decreases when temperatures are cool, and increases when temperatures are warm
recent weather events
Recent Weather Events
  • Increased Precipitation in January 2010
  • The increased rain fall and river flow necessitated the lowering of the inflatable dams
  • Conductivity Concentrations Decreased
  • Sampling was increased to investigate the effects of precipitation on the biogeochemistry of the lake.
