
heavily shaded, leaf litter is
important

shredders / collectors are
abundant
Mid-order Streams

less shaded, algae more
important

grazers abundant
Large Rivers

not shaded, phytoplankton
present

W HAT IS THE CONNECTION BETWEEN
LAND USE AND WATER QUALITY ?
WATER
QUALITY
• Regulated through Clean Water
Act (1972)
• Waters of U.S. must be
“fishable and swimmable” by
1983
• Eliminate all pollution discharge
to waters by 1985
Cuyahoga River, June 22 1969

T HERE IS NO SINGLE DEFINITION OF
CLEAN WATER .
H OW
DO WE USE WATER ?
• Beneficial uses:

Drinking water

Agriculture

Industry

Recreation

Fisheries and
other aquatic life

Aesthetics
H OW
DO YOU KNOW IF
YOU HAVE CLEAN WATER ?
P OINT S OURCE P OLLUTION
• 25% of pollution in the U.S.
• Direct discharge from industry,
sewage treatment plants, etc.
• Easier to identify due to “end of
pipe”
N ONPOINT S OURCE P OLLUTION
•
75% of Pollution in the US
•
General runoff of water contaminated by poor land
use, homes, streets, air, etc.
•
Difficult to identify

WATER Q UALITY ?
•
Maintain the natural habitat for wildlife, native plants,
and your community
•
Support designated uses of waterbody

Fishable

Swimmable
•
Protect and maintain cultural significance
•
Protect drinking water (public health)
•
Esthetically pleasing
W HAT M EASURES ARE PART OF

Some critters aren’t suited for
certain situations and know when
to get out!
C ITIZENS Q UALITATIVE
H ABITAT E VALUATION I NDEX
•
The following all contribute to habitat and combine to
give a final score:

Substrate

Fish Cover

Stream shape and human alterations

Riparian area and local land use

Depth/Velocity

Riffles/Runs
H ABITAT E VALUATIONS
T HE R OLE
OF
F LOW …
•
Helps provide clues to interpret water quality data
•
Channelization
•
Amount of impervious surfaces
•
Affect on pollutant loads & erosion
•
If pollutant increases in high flow, then guess NPS because
concentration increases with runoff
•
If pollutant decreases with high flow, then guess PS because it
is being diluted

•
Chemistry – just a snapshot in time
•
Macroinvertebrates:
•
DO WE MONITOR

Not very mobile

Spend extended period in the water

Have different levels of tolerance to pollution
Macroinvertebrates provide idea of water quality over
extended period of time

W HY W E M ONITOR
•
Identify pollutants and sources
•
Establish baseline data
•
Document changes and trends
•
Measure effectiveness
•
Inform stakeholders
•
Assess use attainment
•
Provide information and data to support modeling
•
Characterize watershed
M ONITORING C HALLENGES
•
Failure to evaluate data regularly
•
Lack of collateral information
•
Poor institutional integration
•
No planned study design


Upstream / downstream

At bottom of watershed

Multiple sites
Physical location

Safety

•

and access/property rights
roadside parking, rocky inclines, high flow conditions, bacteria consideration
Best habitat available

should be characteristic of stream reach, yet should aim to ‘level the playing
field’ between sites
W HEN TO M ONITOR
•
Based on sampling goals/objectives
•
Before and After
•

Monitoring before and after a large rain

Useful for determining types of pollutants washed into stream
after rain and reveal changes that occurs as result of new land
use
Change Over Time

Monitoring the same site twice each year for period of 5 years

Useful in identifying trends and picking up unusual situations

TAKE
HOME THOUGHTS
•
Everything is connected
•
Use long-term thinking
•
Look for the big picture and relationships
•
Focus on object observations, not on blame
•
Consider how pre-existing and popular opinions inform
decisions
•
Gather all the data that you can
