YOUR ORGANIZATIONS’ NAME STREAM MONITORING RESULTS – 201X
Name of presenter Date of presentation
WHY DO WE MONITOR OUR WATERS? To help preserve and protect
Wisconsin’s over 15,000 lakes and 86,000 miles of rivers.
Educate citizens about the status of our water
Obtain water resource data useful for DNR and local decision-making
Advocate for management and protection of our water
Characterize a stream or region
Assess long-term water quality trends
More data on streams for state and federal reporting
Assess potential of streams to support trout
Restoration
DATA USE EXAMPLES
WHERE WE MONITOR
WHAT’S MONITORED?
WHAT’S MONITORED -- LEVEL 1
Water temperature Transparency Macroinvertebrates Habitat Dissolved Oxygen Stream Flow
WHAT’S MONITORED -- LEVEL 2
Continuous temperature pH Dissolved Oxygen Transparency
Varies among projects Projects have included:
E. coli monitoring Crayfish survey Treatment plant outfall thermal
assessment Specific conductance and
chloride Phosphorus Stream flow methods
comparison Other research projects with
DNR biologists
WHAT’S MONITORED – LEVEL 3
Warmer water holds less
oxygen than cold water
Dissolved Oxygenis necessary for all plants and animals.
Lower levels can cause death or distress to
animals.
Turbid or cloudy water hinders light
penetration necessary for plant
growth and production of
dissolved oxygen.
Turbid or cloudy water heats up
faster
Transparency or Water Claritycan be a useful indicator of
runoff from construction sites, industrial discharges & other
sources
Temperaturechange affects all aquatic life

OUR RESULTS: TEMPERATURE

OUR RESULTS: CONTINUOUS WATER TEMPERATURE
OUR RESULTS: CONTINUOUS WATER TEMPERATURE
OUR RESULTS: CONTINUOUS WATER TEMPERATURE
OUR RESULTS: TRANSPARENCY (CLARITY)
Turbidity can affect:– Sight feeders– Water temperature– Plant growth
(therefore oxygen production)
OUR RESULTS: TRANSPARENCY 12, Plant growth hindered 8-20, Brook trout use more
energy to find food; decline in distance over which they can detect prey
15-30, Decline in distance over which rainbow trout can detect prey
30-60, Decline in distance over which bluegill can detect prey
25, Salmonid gills irritated, ability to find food declines; perch growth & foraging declines
40, Brook trout growth rates decline, increase in macroinvertrbrates floating freely downstream

OUR RESULTS: DISSOLVED OXYGEN
D.O. levels below 2 mg/L generally don’t support aquatic life
D.O. below 4 or 5 mg/L won’t support life for long.
D.O. above 7 mg/L is preferable for trout

OUR RESULTS: PH
OUR RESULTS: PH
10 samples below 6 in 20 streams in six counties (Adams, Eau Claire, Milwaukee, Ozaukee, Price and Wood)
12 samples above 9 in eight streams in seven counties (Adams, Douglas, Eau Claire, Marquette, Milwaukee, Ozaukee, and Price)
OUR RESULTS: MACROINVERTEBRATES- BUGS
A way to rate water quality based on organisms that live in the water.
How Healthy is the Stream? Excellent, 3.6+ Good, 2.6 - 3.5 Fair, 2.1 - 2.5 Poor , 1.0 - 2.0

OUR RESULTS: FLOW
The volume of water moving past a cross-section of stream over a set period of time
Measured in CFS= cubic foot per second
Defines the shape, size, and course of the stream
