“pump-out stations” in the Nations inland
waters, and all trash and specifically plastics
materials is to be deposited ashore. Larger
vessels must have a waste management
plan. As reminder to boaters, placards are
posted on boats 26 feet and longer, emphasizing
international marine pollution prevention
agreements, which prohibiting
dumping of trash and discharge of petroleum
based and similar destructive liquids
such as cleaning fluids.
Wake-related shore-line erosion is a
large problem and being combatted with
no-wake areas, and wider use of rip-rap
in use to stabilize the banks. The fines
for violating restricted operations such a
NO-WAKE zone continue stiff. No-motor
areas are being established by states in shallow
waters where marine life develops.
Most states specify maximum noise levels
with maximum noise levels and measured
at specified distances.
INVASIVE SPECIES
Invasive species are plants, animals, or
pathogens that are non-native (or alien)
to the ecosystem under consideration and
whose introduction causes or is likely to
cause harm.
Aquatic nuisance species (ANS) are nonindigenous
species that threaten the diversity
or abundance of native species, the ecological
stability of infested waters, and/or
any commercial, agricultural, aquacultural,
or recreational activities dependent on such
waters. (As defined by the Nonindigenous
Aquatic Nuisance Prevention and Control Act
of 1990 (Dec 29, 2000; PDF | 259 KB)).
Number of nonindigenous species in
selected ecosystems:
• San Francisco Bay/Inland Delta, CA—234
species (plus up to 123 others).
• Great Lakes—139 species
• Hudson River, NY—154 species
• Coos Bay, OR—67+ species
• Florida inland waters—154+ species
• Chesapeake Bay—120+ species
• Hawaii—4,465 species
• U.S. (OTA 1993)—4,500+
Aquatic Hitchhikers Can:
• Reduce game fish populations
• Ruin boat engines and jam steering
equipment
• Make lakes/rivers unusable by boaters
and swimmers
• Increase the costs of operating drinking
water and power plants
• Complicate dam maintenance and interrupt
industrial processes
• Reduce native species populations
• Degrade ecosystems
• Affect human health
• Reduce property values
• Affect local economies of water-dependent
communities
