Exploring Freshwater Streams:
Cherry Creek and Bear Creek Trisha McNiff
BIOL 2081005 Tucker 04/23/2013 Introduction
On April 6th 2013,
our Biology II lab evaluated the health of two freshwater streams in the
Both creeks flow to the South Platte River but are situated in different environments
(urban and suburban) which cause variance in biotic and abiotic indicators of stream health.
presence or absence of bioindicators is dependent on the water chemistry.
Through the study of stream health,
we can gain insight on the stress that humans cause to freshwater habitats.
I think that Bear Creek is healthier than Cherry Creek because it is in a less urban environment
and is less affected by human influences.
If the stream is unhealthy,
there will be fewer
organisms inhabiting it.
The presence or absence of bioindicators depend on the water
Urban stream syndrome is the term used to describe a stream located in an urban
environment that has undergone high levels of stress from city runoff (N.
A Benthological Society 2005).
Urban streams can be adversely affected by the increasing amounts of contaminants,
