Year 5 Annual Monitoring Report
Guilford County, NC
NCDWQ# 00-846
Dear. Mr. Schiller:
The Division of Water Quality (DWQ) 401 Oversight and Express Review Permitting Unit has
reviewed the Year 5 Monitoring Report for the above-referenced site. Our comments on the
report are as follows:
• Channel morphology appears to have maintained stability after five years of monitoring.
Both cross sections and longitudinal profiles have not shown significant changes from
year to year. The monitoring photos did show some herbaceous vegetation growing on
submerged mid-channel bars, but these may be a lingering effect from the droughts
experienced the previous years.
• Evidence of bankfull events have been documented almost yearly, indicating that the
stream maintains good access to its floodplain.
• Vegetative monitoring has shown that the site has exceeded the stem density criterion of
260 stems per acre, and planted areas have appeared to maintain good diversity in both
the stream riparian areas and the wetlands.
• All of the wells at the site met hydrology success criteria, exceeding 12.5 percent of the
growing season (consecutive days) with inundation or saturation.
• Beaver management activities were implemented throughout the 5th year of monitoring,
and no detrimental effects appeared to have resulted from the beavers downstream. It is

acknowledged that once monitoring has been completed, beavers will likely return to the
site.
This site has met the success criteria for both the stream and wetland component of the project.
DWQ feels that the monitoring has demonstrated that this site is trending toward success, that the
site has fulfilled the monitoring requirements outlined in the beginning of the project, and that
further monitoring is not warranted. Pending comment by the U.S. Army Corps of Engineers,
DWQ supports the closeout of this mitigation project.
Please feel free to contact Eric Kulz at [phone] if you have any questions regarding this
project or our comments.
