We use water
to boat on, fish in, and dip our toes into. Even the water that
is not cleaned for our consumption still needs to be clean. Explore
more about how recreation affects water quality.
Recreation
Who
controls how much and what type of recreation is allowed on public
waterways? How important is it to preserve these areas for future
use?
Recreational
waters are vulnerable to the same pollutants that threaten all water.
Perhaps the biggest threat to the quality of recreational waters
is recreation itself.
Threats to
Recreational Waters
The
sheer volume of boats, jet-skis, and swimmers increases the potential
for pollution. Increased activity of any kind can affect sensitive
ecological areas including habitat that wildlife relies on for nesting
or spawning. The type of recreation can also threaten water quality.
While swimming and fishing can be relatively safe and harmless,
boats and jet-skis are powered by gas and oil that can leak into
the water. They also kick up waves, which speed up the natural
erosion
of banks, contributing
sediment to the
waterway.
Although ATVs
(all-terrain vehicles) are used on land, they also present a threat
to water quality. The powerful vehicles tear up the land, exposing
dirt to erosive forces like wind and water. The erosion not only
hurts the landscape, but the dirt and sediment can move into waterways,
impairing water quality.
What
do you think?
What
responsibility do people who enjoy land and water-based activities
have to preserving the environment and water quality? Is there
a way water quality can be maintained while still allowing these
activities?

Jet-skis
Banned by the National Park Service
As
of April 20th, 2002, the National Park Service is banning
personal watercraft (such as jet-skis) from all but 21 of their
379 national parks, recreation areas, and seashores.

Great
blue herons are majestic birds that can trace their ancestors back
to the time of dinosaurs. How have they survived for so long?

Lakes and Navigation
Many
hydrologic modifications made to rivers in order to support commercial
navigation have affected the functions of natural river systems.
Dams were constructed to even out the seasonal changes in water
flows, creating vast lakes behind them.More

Nonpoint
source pollution targeted by EPA
According to the environmental protection agency, or e-p-a, there
are more than 20,000 u.s. lakes, streams and rivers that fail to
meet current water quality standards, as defined by the clean water
act of 1972.
