Construction
of a new culvert and wing barriers to route the western arm of the
Town Branch of the West Fork of the White River under Beechwood
Avenue at its intersection with 18th Street in southwest Fayetteville,
Arkansas, shows the damage that heavy machinery can do to a streambed
in wet weather. Every increase in silt and other pollutants decreases
the ability of the stream to maintain fish and other life, damaging
the stream all the way to Beaver Lake, Northwest Arkansas' main
source of drinking water. The wet, black soil in the photo appears
typical of one of the types of absorbent or hydric soil in Northwest
Arkansas wetland areas. Federal and state storm-water regulations
are designed to protect such watersheds, but enforcement is difficult
and best-management practices require careful planning and complete
cooperation of developers. Training of all operators of heavy machinery
in the reasons for the rules could help a great deal.
