Darby
Creek Watershed Stream Buffer Widths In the spring and summer of 2004 the buffers along all streams were examined to inventory current buffer conditions. A combination of a driving survey and aerial photography were used to calculate actual buffer types (trees or grass) and widths. The information was recorded in GIS to create maps and statistics on riparian buffers. The following figure summarizes the vegetated buffer widths in the entire watershed.
Figure 80 defines the width of grassed buffers in the Darby
Watershed. County maintained ditches
are not included in the totals below. Nearly
61 miles of county maintained ditches have a grassed easement of 10 feet.
Over 27 percent of the watershed has a 100 foot wooded
buffer or greater on either side of the stream.
There are several areas in the watershed that have over 1,000 feet of
wooded buffer along Little and
This stream buffer analysis explored both the width and type of buffer (forest or grass) in the Darby watershed. The following section describes stream modifications that were also recorded during this same research inventory of stream buffers in 2004.
