Importance of Dissolved O2

• Like terrestrial animals, fish and other aquatic
  organisms need oxygen to live.
• Oxygen also is needed by virtually all algae and
  all macrophytes, and for many chemical reactions
  that are important to lake functioning.

3
Elberta Crate

• The Elberta Crate Regional Storm Water Facility
  is a retention pond for urban storm water.
• Some pollutants and trash carried along with
  storm water are diverted and contained.
• During heavy rainfall events, the storm water
  bypasses Elberta and flows directly to Munson
  Slough and Lake Munson.

4
Lake Munson

• For years, Lake Munson has ranked as one of
  Florida's most polluted lakes.
• Storm water carrying pollution from streets and
  lawns flows from FSU and much of central
  Tallahassee south to Lake Munson and then into
  sinkholes where it enters the aquifer.
• Lake Munson has recently undergone a restoration
  process to improve recreational value.

5
Lake Henrietta

• The Lake Henrietta basin, located upstream of
  Lake Munson.
• Historically provided storm water treatment for
  the natural flow through the system.

6
Lake Bradford

• The Florida State University Reservation is a
  73-acre facility, with 10 active acres, located
  on beautiful Lake Bradford.

7
Research Problem

• Measure the level of dissolved oxygen within
  water in Lake Munson, Lake Bradford, Elberta
  Crate, and Lake Henrietta over a period of 4
  hours.

8
Hypothesis

• The amount of dissolved oxygen in the lakes will
  be lower during the morning, due to lower
  temperatures, reduced photosynthesis, and
  consumption of O2 during the night.
• The amount of dissolved oxygen in Lake Henrietta,
  Elberta Crate and Lake Munson should be lower
  than Lake Bradford because of cultural
  eutrophication.

9
Procedure

• Three samples of water were collected and tested
  for dissolved oxygen levels at three different
  times of day at each lake.
• Each lake was tested on a different day though we
  tried to ensure that weather conditions were as
  similar as possible for testing.
• The water temperature was recorded before each
  trial.

10
Results(on average)
11
Conclusion

• The amount of dissolved oxygen tended to increase
  or stay the same as the time of day progressed
  for all lakes except Lake Bradford.
• The reason for the decrease of dissolved oxygen
  during the night time is because photosynthesis
  occurs only during day time.

12
Improvements

• Collect more samples to get a better spread of
  the data.
• Schedule testing on days with the exact same
  temperature or perform all tests at the same
  times and on the same day.
