PRAB MEETING
Minutes
December 14, 1982
The Parks and Recreation Advisory Board came to order at
4 pm at the Continuing Education Building.
MINUTES: Minutes were approved as mailed.
BUSINESS:
1. Model Airplane Flying Club: Members representing the Model
Airplane Flying C ub were present at the Board meeting.
They wanted to stress to the Board that looking into the
future they feel they will have to leave their present
location and find another location more permanent. They
are still very interested in the flood plain out by
Industrial Park. The PRAB said that they are concerned
and are waiting for the City to determine what land will
be available to the Parks Department and then the Board
will need to make a master plan of the development of
that area.
2. Environmental Study Center: Hal Brown presented the data
from his study at Lake Fayetteville. The Board discussed
possible pollutants of the Lake with Hal. Hal is working
in cooperation with the University, Health Department and
Sanitation concerning the problem. The Board discussed
having an Open Forum with Hal and other specialist about
eutrophication of Lake Fayetteville.sometime in February.
Hal Brown reported that he would like his classes to help
plant approximately 4,000 pinie:trees around the perimeter
of the Environmental Study Center. They need the Parks
assistance in plowing the area before planting the trees
in January. Diiector-_Dale Clark said the Parks Department
would have the ground ready.
3. Lake Ordinances: Motion Melton/Knight: To add to the Lake
Ordinances under #1. ,..."The Boat Docks will be closed
on December 24 thru January 14." This time will be the
boatdock operator's vacation time.

EUTROPHICATION
• The Plague of Plenty
What do the homeowners of Northwest Arkansas, area agri-business,
and Fayetteville's beleaguered sewage treatment plant have in common?
All have been identified in published reports as point and non -point
sources for pollution of our area waterways, particularly Beaver Lake.
The predicted global environmental crisis of the eighties, water qual-
ity, has found an early locus in our region, as we are confronted by-
the complex ecological problem called eutrophication. This report will
explain some of the symptoms of eutrophication, its development, and
its consequences.
Like many other environmental problems, eutrophication is a natural
process unbalanced by man's activities. In undeveloped areas, a eu-
trophic lake is an old lake entering the final stages of a natural
aging process that has taken thousands of years. With its abundance
of life and food, the ancient lake is "well nourished" as the meanings
of the root words eu and trophein imply. The nourishment, organic nu-
trients most commonly encountered as fertilizer and household clean-
ser, is critical to eutrophication, for the lake ecosystem responds
I to organic nutrients with definite shifts -in plant::and-animal'.popuia-
tions.
Phytoplankton, micro-
scopic plants that sup-
port a free-floating com-
munity, react quickly to
increased nutrient loading
of the water. Their lux-
urient growth, analogous
to fertilized gardens, is
an "algal bloom". Tiny
invertebrates, the zoo -
plankton, graze on the
algae and flourish.
Some blooms are haz-
ardous to livestock and
humans. Primitive blue-
green algae can become
trapped at the surface,
forming a stinking scum
that is toxic and corrosive.
' II
from The Water Naturalist
• Although blooms of individual "nuisance" algae are a spectacular symp-
tom of eutrophication, changes in other populations more directly por-
( 1 tend the lake's demise and succession to swamp, marsh and climax eco -
1 ) systems. Bacteria feed directly on the organic nutrients, breaking
down fats, carbohydrates and proteinaceous compounds, and utilizing
oxygen dissolved in the water to support this metabolism. As the
level of dissolved oxygen falls, susceptible forms of higher animal
life suffocate. Fish kills are a symptom of this advancing eutro-
phication and oxygen depletion.

from Arkansas water: Tilly wait for the Crisis?
This rich supply of dead organic material supports tremendous growth
of the bacteria and allied decomposer organisms. The bottom of a eu-
trophic lake has been described by one author as a "putrifying ooze
composed of the disintegrating bodies of plankton organisms or de-
tritus". The bottom muck, or benthos, eventually fills the lake,
which terminates as a viable body of water.
Eutrophication, the plague of plenty, is the natural aging process
of a lake accelerated by man's activities. Septic tank and field
leakage, fertilizer washed by rains, and sewage plant effluent are a-
mong the main causes of accelerated eutrophication. All of these
practices introduce phosphates, nitrates, ammonia and other organic
nutrients into our water. Area lakes are threatened with drastically
shortened lifespans by the "plenty" man dumps into them.
