Water is the most critical resource issue of
our lifetime and our children's lifetime.
The health of our waters is the principle
measure of how we live on the land.

20. THE ROCK RIVER
COALITION
“Our mission is to educate and provide
opportunities for people of diverse interests to
work together to improve the environmental,
recreational, cultural, and economic resources of
the Rock River Basin.”
23. WHAT DOES THE ROCK RIVER
COALITION DO?
Citizen Stream Monitoring
Citizen Wetland Monitoring – restoring and
monitoring Zeloski Marsh
Restoring the Rock – participating in developing the
Rock River Recovery Plan
Water Star Wisconsin -- to honor municipalities who
do outstanding work
28. What is monitored?
1. Temperature
2. Dissolved oxygen
3. Biotic Index
4. Flow – velocity
5. Transparency
6. Habitat Information
29. Why Temperature?
Affects metabolic rates of aquatic species
Affects the amount of oxygen that can be
dissolved in the water
Affects sensitivity of organisms to disease,
parasites and pollutants
30. What can cause temperatures to rise?
Suspended solids (from runoff)
Runoff from warm pavement
Industrial discharges
31. WHY DISSOLVED OXYGEN?
Plants and animals need
dissolved oxygen to survive.
Without dissolved
oxygen
fish and macro-
invertebrates leave the
area or die
32. FACTORS THAT AFFECT AMOUNT
OF DISSOLVED OXYGEN
Warm water
Cold water
High levels of sediment Clear water
Excessive organic materials A lot of wave action
34. FACTORS THAT COULD DECREASE CLARITY
Runoff from
construction sites
Runoff from
agricultural fields
35. WHY MEASURE STREAM FLOW
Defines the shape, size and course of the stream.
Integral to habitat.
36. Decreased flow -- withdrawals for
irrigation, domestic or industrial
purposes
Dams and channelization
Increased flow -- due to runoff
37. WHY BIOTIC INDEX?
Indicator species –
Poor-quality streams
will gradually lose
pollutant-sensitive
animals until only the
pollutant-tolerant
species are left

that a small group of thoughtful,
committed citizens
can change the world;
indeed, it's the only thing
that ever has.

What does this mean….Water quality is affected by land use
Whose Responsibility is Clean Water? Clean Water is Everyone’s Rresponsibiltiy
For each 10°C (18°F) rise in temperature the metabolic rate doubles colder water greater amount of oxygen that can be dissolved in water
limiting factor for growth and fish health D.O. minimums vary for different waterbodies: Trout streams in spawning season: 7 mg/L Trout streams outside of spawning season: 6 mg/L Fish or aquatic life waters: 5 mg/L Limited forage fish waters: 3 mg/L Limited aquatic life waters: 1 mg/L
