What other
factors influence
our lake levels?
26. Helping to Educate Minds and Changing Hearts
Why are many of Florida’s lakes and
rivers a dark color?
B. The soil makes the water
appear to be a dark
color.
C. Tannins released from
decomposing plant
material stain the water a
dark color, like a tea bag.
A. The water is polluted.
D. None of the above.
27. Helping to Educate Minds and Changing Hearts
The correct answer is C.
Tannins released from
decomposing plant material stain
the water a dark color, like a tea
bag.
28. Helping to Educate Minds and Changing Hearts
You’re correct.
It is part of the natural process for tannins to be
released and the river’s ecosystem and
inhabitants are adjusted to a dark water
system.
29. Helping to Educate Minds and Changing Hearts
Who lives in a watershed?
A. Only those people who live next to
a water body.
B. Everyone
C. People who live
within 5 miles of
a water body.
D. None of the
above.
30. Helping to Educate Minds and Changing Hearts
The correct answer is B. Everyone
lives in a watershed.
32. Helping to Educate Minds and Changing Hearts
What contributes to algae blooms in
a river?
A. Overfertilizing lawns and landscapes
B. Stormwater draining into waterways
C. Warm temperatures
D. All of the above
E. None of the above
33. Helping to Educate Minds and Changing Hearts
The correct answer is D. All of the
above.
34. Helping to Educate Minds and Changing Hearts
You’re right.
Everyone needs to be careful to:
Follow label directions when using fertilizers
Not apply near or along the edges waterways
Use slow-release fertilizers
Apply only the amount needed by the plants
35. Helping to Educate Minds and Changing Hearts
How can you and your dog help

A. Don’t walk your dog near a waterway.
B. Collect the dog’s waste in a plastic bag and
put it in a storm drain.
C. Pick up after your dog and
dispose of the waste properly.
D. All of the above.
E. None of the above.
36. Helping to Educate Minds and Changing Hearts
The correct answer is C. Pick up after
your dog and dispose of the waste properly.
Proper disposal means placing it in a trash can
not down a storm drain.
37. Helping to Educate Minds and Changing Hearts
Right answer.
Remember, proper disposal means placing it in
a trash can not down a storm drain.
38. Helping to Educate Minds and Changing Hearts
What is the most COMMON way trash
enters our waterways?
A. After a rain, trash moves to a storm drain
and empties into a water body.
B. Trash blows out of a trash can or dumpster.
C. Trash is thrown directly into a water body.
D. All of the above
E. None of the above
39. Helping to Educate Minds and Changing Hearts
That’s not right. The correct
answer is A. After a rain, trash
moves to a storm drain and
empties into a water body.
40. Helping to Educate Minds and Changing Hearts
You’re right.
It is important that only rain go down a storm
drain.
Pick-up any litter you find.
Never put lawn clippings or used motor oil
down a storm drain.
All storm drain eventually lead to our
waterways.
41. Helping to Educate Minds and Changing Hearts
What is the relationship between
leaky car fluids and a river otter?
A. Both can be found in
the river.
B. Both can be wet and slippery.
C. Both are brown.
D. All of the above

The correct answer is D. All
of the above.

Editor's Notes
Confined on the east by the Lake Wales Ridge
Confined on the west by a series of low parallel ridges—Same ones that confine Little Creek basin and serves as a watershed divide
Drains into Lake Louisa
Because of the flat topography, water comingles with several basins
The average channel slope south of 474 is 0.6 ft./mile

Eutrophic = well nourished
Eutrophication occurs naturally over hundreds of years
Human activities can greatly speed up this process
Excess nutrients
stimulate growth of
plants and algae
Most abundant nutrients are nitrogen & phosphorus
Nutrients are contained in fertilizers, pet waste, leaves, debris & some detergents
A lake that’s too well nourished may become hypereutrophic and have algae blooms
It is part of the natural process for tannins to be released and the river is called a dark water system.
In these systems, sunlight is limited in how deeply it can penetrate through the water. Sunlight is important for photosynthesis. Photosynthesis helps to place oxygen in the water and is important for the health of a river.

A watershed is the land area that water moves through and drains into a body of water.
When it rains water runs downhill into small creeks that run into bigger streams and then into rivers until it reaches the ocean.
We all live in a watershed, no matter where we live. And we all have an impact on the river.
When it rains water runs downhill into small creeks that run into bigger streams and then into rivers until it reaches the ocean. The St. Johns River watershed is made up of many smaller watersheds such as the Black Creek, Oklawaha, or Wekiwa watersheds.
We all live in a watershed, no matter where we live. And we all have an impact on the waterways.
In warmer weather, algae blooms can occur.
They are often caused by the overuse or misuse of fertilizers on landscapes.
This fertilizer and other sources of nutrients run into our waterways after a rainfall.
It is important that only rain go down a storm drain.
Pick-up any litter you find.
Never put lawn clippings or used motor oil down a storm drain.
All storm drain eventually lead to our waterways.
Both river otters and leaky
car fluids, such as oil,
gasoline, or antifreeze, can
be found in our waterways.
By maintaining our cars properly and repairing leaks as soon as possible, we can prevent these types of pollutants from getting in our waterways.
