Perhaps the biggest threat to the quality of recreational waters
is recreation itself.
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

(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.

Lakes and Navigation
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

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.
